Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource selection method, an apparatus, and a user equipment.

Background

Currently, mechanisms to support preemption in New Radio (NR) sidelink are available. For example, in the Mode2 resource allocation Mode, the resource pre-assignment mechanism is supported, that is, when the reserved resources of one UE overlap (e.g., partially overlap) with the reserved resources of other UEs with higher priority traffic, and the SL-RSRP measurement value of these UEs on the relevant resources is greater than a certain associated SL-RSRP threshold value, the UE with low priority traffic triggers the resource reselection.

Thus, after the Pedestrian Ue (PUE) is introduced, the preemption mechanism may cause the terminal device performing resource selection to preempt the resources of the PUE, thereby causing the performance of the PUE to be reduced. For example, in NR V2X, it is necessary to support communication between a PUE and a car ue (VUE), and if the PUE and the VUE use the same resource pool and the resource pool supports a preemption mechanism, preemption of resources of the PUE by the VUE or preemption of resources of the PUE by the PUE may cause performance degradation of the PUE with the preempted resources, and thus may cause performance degradation of data packets sent by the PUE in the system.

Disclosure of Invention

The embodiment of the application provides a resource selection method, a resource selection device and user equipment, so as to solve the problem that the performance of a PUE is reduced in a scene that the PUE supports a preemption mechanism.

In order to solve the technical problem, the present application is implemented as follows:

in a first aspect, an embodiment of the present application provides a resource selection method, which is applied to a UE, and the method includes: when the preset condition is met, determining an alternative resource set according to the resource information of the first resource in the resource selection window; selecting a target resource from the alternative resource set; wherein the predetermined condition comprises at least one of: the UE detects reserved resources of a first type UE, and the UE is the first type UE; the resource information includes at least one of: priority information, a measurement result, a measurement threshold, and a UE type of the UE to which the first resource belongs.

In a second aspect, an embodiment of the present application provides a resource selection apparatus, including: the determining module is used for determining an alternative resource set according to the resource information of the first resource in the resource selection window when the predetermined condition is met; the selection module is used for selecting the target resource from the alternative resource set determined by the determination module; wherein the predetermined condition comprises at least one of: the method comprises the steps that UE detects reserved resources of first type UE, wherein the UE is the first type UE; the resource information includes at least one of: priority information, a measurement result, a measurement threshold, and a UE type of the UE to which the first resource belongs.

In a third aspect, an embodiment of the present application provides a UE, including a processor, a memory, and a computer program stored on the memory and executable on the processor, where the computer program, when executed by the processor, implements the steps of the resource selection method according to the first aspect.

In a fourth aspect, the present application provides a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the steps of the resource selection method according to the first aspect.

In this embodiment of the present application, when detecting that the reserved resource of the first type UE and/or the UE is the first type UE, the UE may determine an alternative resource set according to resource information of the first resource in the resource selection window, and then select a target resource from the alternative resource set. Therefore, when the first type UE supports the preemption mechanism or detects that the first type UE is preempted, the first type UE can select or reselect resources based on the resource information of the first resource in the resource selection window, so that the probability of the first type UE that the resources are preempted is reduced, and frequent resource reselection by the first type UE is avoided, thereby reducing the energy overhead and performance loss of the first type UE, and further achieving the purpose of saving power.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Technical terms related to the embodiments of the present application will be explained below.

1. Side link (sidelink)

The LTE system supports sidelink for direct data transmission between UEs without using a network device, that is, data transmission between UEs is directly performed over an air interface. The data transmission is in the form of a broadcast. Sidelinks may also be referred to as sidelinks, or sidelinks.

It should be noted that sidelink, although it can be used to support basic security-type communication of vehicle (V2X), is not suitable for other higher-level V2X services. The 5G NR (New Radio) system will support more advanced sidelink transmission design, such as unicast, multicast or multicast, etc., so that more comprehensive service types can be supported.

The design of the LTE sidelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes), or V2X communication and the like. The internet of vehicles communication includes various services, such as basic security type communication, advanced (automated) driving, formation, sensor expansion, and the like. Since LTE sidelink supports only broadcast communication, and is therefore mainly used for basic security class communication, other advanced V2X services with strict QoS requirements in terms of latency, reliability, etc. will be supported by NR sidelink.

Among them, communication of V2V is supported in NR V2X.

2. sidelink resource allocation

The LTE sidelink design supports two resource allocation modes, namely a Scheduled resource allocation (Scheduled resource allocation) mode and an autonomous resource selection (autonomous resource selection) mode. The former is controlled by network side equipment and allocates resources for each UE, and the latter is selected by the UE autonomously. Wherein, LTE sidelink mode1 is a scheduling resource allocation mode of D2D, and LTE sidelink mode2 is an autonomous resource allocation mode of D2D; LTE sidelink mode 3 is the scheduling resource allocation mode of V2X, and LTE sidelink mode 4 is the autonomous resource allocation mode of V2X.

The basic working principle of the LTE sidelink mode 4 is as follows:

measurements are made within the detection window (sensing window), demodulation allocation (SA) and interference measurements are made within each detection TTI. Specifically, the UE performs resource selection according to the following steps:

1) excluding resources for the UE to send data.

2) And the terminal demodulates the received SA to obtain the reserved resources of other UE and excludes the reserved resources of other UE.

3) Energy detection is carried out in the sending window, RSSI (received signal strength indication) is measured, and resources with large interference are eliminated according to the measurement result.

4) Within the sending window, one subframe (subframe) is randomly selected from the 20% resource with the minimum interference for periodic resource reservation.

In addition, NR V2X defines two resource allocation modes, one mode1, for scheduling resources for the base station; the other is mode2, the UE itself decides what resources to use for transmission. At this time, the resource information may be from a broadcast message of the base station or preconfigured information. The UE may be mode1 and/or mode2 if it is operating within the range of the base station and has an RRC connection with the base station, and may only operate in mode2 if it is operating within the range of the base station but has no RRC connection with the base station. If the UE is out of range of the base station, it can only operate in mode2, performing V2X transmissions based on the preconfigured information.

For mode2 in NR V2X, the basic operating principle is as follows:

1) after the resource selection procedure is triggered, the TX UE first determines a resource selection window (where the lower boundary of the resource selection window is at time T1 after the resource selection procedure is triggered, the upper boundary of the resource selection window is at time T2 after the resource selection procedure is triggered, T2 is a value selected by the UE within a data delay (PDB) of its TB transmission, and T2 is no earlier than T1).

2) Before resource selection, the UE needs to determine an alternative resource set (candidate resource set) for resource selection, compare the RSRP correspondingly measured according to the resource in the resource selection window with a corresponding RSRP threshold (i.e. RSRP threshold), and if the RSRP is higher than the RSRP threshold, the resource is considered to be excluded, that is, if the RSRP is lower than the RSRP threshold, the resource may be included in the alternative resource set. The RSRP measured corresponding to the resource in the resource selection window is a value measured by the UE in a time slot where the SCI information of the resource is scheduled, for example, the RSRP may be a value obtained by measuring an SCI (or a Physical Sidelink Control Channel (PSCCH)) or a value obtained by measuring a physical Sidelink shared Channel (PSCCH) scheduled in the time slot where the SCI is located.

3) After the alternative resource set is determined, the UE randomly selects resources in the alternative resource set.

In addition, the UE may reserve transmission resources for the next transmission in the current transmission. And NR V2X supports a chained resource reservation manner, that is, one Sidelink Control Information (SCI) may reserve the current resource, may reserve two additional resources at most, and may indicate two reserved resources in the next resource. In the resource selection window, resources can be continuously reserved in a dynamic reservation mode.

3. Partial detection (Partial sensing)

Part of the detection in LTE V2X is designed mainly for power saving, and is to support communication in P2V, and the PUE supports two modes of resource selection. One is random resource selection; and the other mode is to perform partial detection first, select resources based on the result of the partial detection and perform semi-static resource reservation. The PUE selects which mode is configured by the RRC, and when the RRC is configured to support the resource selection of the two modes, the PUE determines which resource selection mode is adopted.

Specifically, the manner in which the terminal performs partial detection and performs resource detection is as follows:

wherein, as shown in FIG. 1, the PUE detection window is a window in the range of [ n-1000, n ]. Window A within [ n + T1, n + T2] within the selection window is the selection window of the higher-level configured PUE. The PUE detects SCIs sent by other terminals in the detection window B, and presumes the resource reservation condition of the other terminals in the window A according to the detected SCIs and the reservation period, and the PUE can exclude resources which do not meet the conditions in the selection window according to the information. And selecting at least 20 percent (20 percent of the window length) of the rest resources as a candidate resource set, reporting the candidate resource set to the MAC layer, and randomly selecting one resource from the candidate resource set by the MAC layer as the candidate resource of the PUE. The PUE makes periodic reservations for the selected resources, the reservation period being indicated in the SCI.

4. sidelink preemption (Pre-preemption) mechanism

In Mode2, the resource pre-projection mechanism is supported. The resources already reserved by one UE overlap (partially overlap) with the resources reserved by other UEs with higher priority traffic, and when the SL-RSRP measurement value of these UEs on the relevant resources is greater than a certain associated SL-RSRP threshold value, the UE with low priority traffic triggers the reselection of resources. The associated SL-RSRP threshold value may be a predefined or base station pre-configured fixed RSRP threshold. The fixed value may determine the threshold value X based on a mapping relationship between information such as priority, PDB, traffic type, QoS, and reliability of a service to be transmitted by the UE itself (i.e., the current TB) and the SL-RSRP threshold value.

The following will exemplarily describe a resource selection method provided by the embodiment of the present invention by taking UE as an example.

Fig. 3 shows a flowchart of a resource selection method provided in an embodiment of the present application, and as shown in fig. 3, the resource selection method may include steps 201 and 202:

step 201: and when the UE meets the preset condition, determining an alternative resource set according to the resource information of the first resource in the resource selection window.

Step 202: the UE selects a target resource from the set of alternative resources.

Wherein the predetermined condition comprises at least one of: the UE detects the reserved resource of the first type UE, and the UE is the first type UE; the resource information includes at least one of: priority information, a measurement result, a measurement threshold, and a UE type of the UE to which the first resource belongs.

In this embodiment of the present application, when the UE detects the reserved resource of the first type UE, the first resource includes the reserved resource of the first type UE.

It is to be understood that the predetermined condition may include at least one of: the UE detects the reserved resources of the first type of UE and a partial detection mechanism of the UE is enabled.

In the embodiment of the present application, when the partial detection mechanism of the UE is enabled, it indicates that the UE is a first type UE. When the UE is a first type UE (it may also be understood that when a partial detection mechanism is enabled), that is, when the first type UE executes the resource selection scheme, the first resource may include a reserved resource of the first type UE, or may not include the reserved resource of the first type UE, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the measurement result may include a measurement value. For example, the measured value corresponding to the first resource may include: reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), Signal-to-noise and Interference Ratio (SINR), Signal-to-noise Ratio (SNR), Block Error rate (BLER).

Optionally, in this embodiment of the present application, the first type UE may be a PUE, and the second type UE may be a VUE.

Optionally, the first resource may be a resource indicated in the SCI or the DCI, may also be a periodic resource indicated in the SCI or the DCI, and may also be an aperiodic resource indicated in the DCI, which is not limited in this embodiment of the present invention.

Optionally, in this embodiment of the present application, the resource information further includes enabling information, where the enabling information is used to indicate whether a part of the detection mechanism of the UE is enabled.

Optionally, in this embodiment of the application, when the resource information includes a UE type of the UE to which the first resource belongs, the UE may exclude the reserved resource of the target UE type based on the resource information and a predetermined exclusion rule. Wherein the predetermined exclusion rule includes excluding reserved resources of the target UE type; the target UE type may be the first type (e.g., PUE) described above.

Optionally, in this embodiment of the present application, before acquiring the resource information of the first resource in the resource selection window, the UE receives, in the resource detection window, at least one SCI corresponding to the first UE. Wherein, SCI corresponding to each first UE carries priority information; the first resources include reserved resources of each of the at least one first UE in a resource selection window. It is to be understood that the priority information includes priority information carried in the corresponding SCI of each of the at least one first UE.

It should be noted that the reserved resource of the UE in the embodiment of the present application may be understood as a resource reserved by the UE, and may also be understood as a resource occupied by the UE, which is not limited in the embodiment of the present application. For example, the reserved resources of the PUE may be referred to as resources occupied by the PUE; similarly, the reserved resource of the VUE can be referred to as a resource occupied by the VUE.

The UE in the embodiment of the present application may determine the alternative resource through at least three implementation manners.

First possible implementation (increasing priority of first type UE)

Specifically, the priority of the first type of UE may be increased, so that when the UE performs resource exclusion, the reserved resource of the first type of UE may be considered as an occupied resource, and then the reserved resource of the first type of UE may be preferentially excluded, thereby reducing the probability that the reserved resource of the first type of UE is preempted.

Optionally, in this embodiment of the present application, the priority information is used to indicate: the priority of the first type of UE is highest, and/or the priority of the reserved resources of the first type of UE is highest.

For example, in the case that the UE is a first type UE, the priority information is used to indicate that the priority of the UE is the highest. Thus, other UEs cannot occupy the reserved resources of the first type UE.

For example, when the VUE performs resource preemption, if the reserved resource of the PUE is detected, the VUE considers that the reserved resource cannot be occupied (i.e., excludes the reserved resource of the PUE). Of course, it can be considered as excluding the occupied resources of the PUE.

Optionally, in this embodiment of the present application, the priority of the first type of UE is set according to a first preset rule; wherein the first preset rule includes at least one of:

setting the priority of the first type of UE to be greater than or equal to the priority of the data packets transmitted by the UE,

setting the priority of the first type of UE according to a preset priority offset value,

the priority of the first type of UE is within a preset priority range.

For example, the UE may set or acquire the priority of the first type UE according to at least one of the following manners: 1. defining a priority offset value for a first type of UE; 2. and defining the value range of the priority of the first type UE.

For example, the priority of the first type UE may be a priority of a reserved resource of the first type UE, or may be a priority of a data packet transmitted by the first type UE. In one example, the priority of the reserved resources of the PUE may be set such that the priority of the reserved resources of the PUE is higher than the priority of other transmitted data packets, or such that the priority of the reserved resources of the PUE is within a higher priority range (e.g., the priority of the restricted PUE needs to be less than a predetermined priority).

It should be noted that the first preset rule applies to: all resource pools configured with P2V or V2P, or resource pools configured with the first preset rule (for example, if a certain resource pool is configured with the first preset rule, it is considered that the resource pool needs to use the rule).

Further, whether to map the priority of the first type UE according to the first preset rule in a certain resource pool may be explicitly indicated (for example, 1bit indicates whether the first preset rule is adopted in the resource pool, if 1, it indicates that the resource pool needs to perform priority setting according to the rule, and if 0, it indicates that the resource pool needs to perform priority setting according to other rules, but does not adopt the rule), or implicitly indicated.

Further optionally, in this embodiment of the present application, the preset priority offset value is related to a Channel Busy Rate (CBR) (e.g., a range of CBRs) of the UE; or, the preset priority offset value is predefined or configured by a high-level signaling or indicated by Downlink Control Information (DCI) or indicated by Sidelink Control Information (SCI); alternatively, the lower threshold of the preset priority range is predefined or configured by higher layer signaling or DCI or SCI.

The first preset rule includes a scenario in which the priority of the first type UE is set according to a preset priority offset value.

Example 1: the RRC may configure a corresponding P _ delta value (i.e., the above-mentioned preset priority offset value) for each CBR range. When the CBR is larger than the CBR threshold value, the P _ delta is 0, otherwise, the P _ delta adopts a configured value. Wherein the CBR threshold value is a value predefined by a protocol/configured by a network/preconfigured.

Example 2: the UE may obtain P _ pri according to the priority rule of the second type UE, and the priority of the first type UE is P _ pri + P _ delta. Wherein the priority rule of the second type UE may include: the priority is obtained from the SCI or from higher layer signaling.

Second possible implementation (priority exclusion of reserved resources for first type of UE)

Optionally, in this embodiment of the present application, the first resource includes: the reserved resources of the first type of UE and the reserved resources of the second type of UE. The step 201 may include the following steps 201 a:

step 201 a: and under the condition that the priority of the reserved resources of the first type UE is the same as the priority of the reserved resources of the second type UE, the UE excludes the reserved resources of the first type UE.

For example, when the UE detects the reserved resource of the PUE and the reserved resource of the VUE, if the priority of the reserved resource of the PUE is the same as the priority of the reserved resource of the VUE, the reserved resource of the PUE is preferentially excluded.

For example, assuming that the priority of the PUE is configured as the highest priority, the priority of the VUE may be set lower than the priority of the PUE, and there may be a case of being configured as the highest priority. For example, the priority is 0 to 7 from high to low, the VUE priority may have a configuration of 0 to 7, and if the priority of the PUE and the priority of the VUE are both set to 0, the reserved resources of the PUE may be directly excluded at this time.

For example, the UE may perform the first exclusion with the priority as the first class, and then perform the exclusion with the UE type as the second class in the same class of priority.

Illustratively, for the VUE as an example, the VUE performs resource exclusion based on priority, and then performs resource exclusion based on UE type. That is, the VUE may preempt the reserved resource of the VUE in the resource pool, and if the number of resources does not meet the requirement, preempt the reserved resource of the PUE. Specifically, resource preemption can be performed according to the priority of the PUE.

Optionally, in this embodiment of the present application, the step 201 may include the following steps:

step A1: and if the reference measurement value corresponding to any first resource is detected to be greater than or equal to the target measurement threshold, the UE excludes the any resource.

For example, taking the measured value as RSRP as an example, the following manner is adopted when the UE measures RSRP of the PUE and/or the PUE measures RSRP. For example, when the UE measures the RSRP of the PUE as RSRP _ real, the probability that the resource occupied by the PUE is selected by the UE can be reduced by increasing the reference RSRP measurement value of the reserved resource of the PUE when the resource exclusion is performed. For example, the increased reference RSRP measurement (e.g., RSRP _ real + RSRP _ delta) is compared to an RSRP threshold. Wherein the RSRP _ delta is a value predefined/preconfigured/configured by the protocol, or the value of RSRP _ delta is related to the CBR.

Optionally, in this embodiment of the present application, in a case that the measurement result includes a reference measurement value, the resource selection method provided in this embodiment of the present application may further include the following steps:

step A2: and the UE configures the detection parameters of the first type of UE.

Wherein the detection parameters include at least one of: a second preset rule of the target measurement threshold, a third preset rule of the reference measurement value, a measurement threshold offset value and a measurement offset value.

For example, the embodiment of the present application may preferentially exclude the reserved resources of the first type UE by defining or configuring a relationship between the UE priority and the target measurement threshold. For example, the measurement threshold is increased, the increase amount is beta _ threshold, e.g. the measurement value is increased, the increase amount is beta, the above beta value and beta _ threshold value may be protocol predefined, or RRC pre-configuration, or RRC/MAC CE configuration, or DCI/SCI indicated values.

In an example, taking the measured value as RSRP as an example, if the RSRP threshold value obtained according to the mapping rule between the priority defined by the first protocol version (e.g., R16) and the RSRP threshold value is RSRP _ th, when the UE performs resource exclusion, it may be determined whether the resource of the first type UE is excluded based on the RSRP threshold value RSRP _ th-beta.

Further optionally, in this embodiment of the application, when any of the first resources is a reserved resource of a first type of UE, the second preset rule includes: setting a target measurement threshold based on the first original measurement threshold and the first measurement threshold offset value; or, when the UE is a first type UE, the second preset rule includes: a target measurement threshold is set based on the second raw measurement threshold and the second measurement threshold offset value. It should be noted that, the first measurement threshold offset value and the second measurement threshold offset value may be positive values or negative values, which is not limited in this embodiment of the present application.

For example, the setting the target measurement threshold based on the first raw measurement threshold and the first measurement threshold offset value may include: and subtracting or adding a first measurement threshold offset value on the basis of the first original measurement threshold to obtain a target measurement threshold.

For example, setting the target measurement threshold based on the second raw measurement threshold and the second measurement threshold offset value may include: and adding or subtracting the second measurement threshold offset value on the basis of the second original measurement threshold to obtain the target measurement threshold.

For example, the original measurement threshold is determined by searching a table corresponding to the RRC based on the priority of the UE and the priority parameter of the priority corresponding to the reserved resource. For example, the first raw measurement threshold is obtained by looking up a table based on the priority of the UE and the priority corresponding to the reserved resource of the first type UE.

For example, when performing resource exclusion, the UE may obtain the used RSRP threshold (i.e. the above target measurement threshold) according to at least one of the following manners. Mode 1: when measuring the occupied resources of the first type of UE, the value of RSRP threshold is considered as the acquired RSRP threshold (i.e. the raw measurement threshold) minus the first measurement threshold offset value. Mode 2: when measuring by the first type of UE, the value of RSRP threshold is considered to be the acquired RSRP threshold (i.e. the raw measurement threshold) plus the second measurement threshold offset value.

Illustratively, the first measurement threshold offset value is predefined or protocol-specified or preconfigured or first bearer-configured or indicated by the first indication information; and/or the first measurement threshold offset value is related to the CBR of the UE. Wherein, the first carrier comprises RRC or MAC CE; the first indication information includes: DCI or SCI.

Illustratively, the second measurement threshold offset value is predefined or protocol-specified or preconfigured or second bearer-configured or indicated by second indication information; and/or the second measurement threshold offset value is related to the CBR of the UE. Wherein, the second carrier comprises RRC or MAC CE; the second indication information includes: DCI or SCI.

Further optionally, in this embodiment of the application, when any of the first resources is a reserved resource of the first type of UE, the third preset rule includes: obtaining a reference measurement value corresponding to the reserved resource of the first type UE based on the measurement value corresponding to the reserved resource of the first type UE and a first measurement deviation value; or, when the UE is a first type UE, the third preset rule includes: and obtaining a reference measurement value corresponding to any first resource based on the measurement value corresponding to any first resource and the second measurement deviation value. It should be noted that the first measurement offset value and the second measurement offset value may be positive values or negative values, which is not limited in this embodiment of the application.

For example, the obtaining a reference measurement value corresponding to the reserved resource of the first type UE based on the measurement value corresponding to the reserved resource of the first type UE and the first measurement offset value may include: and adding or subtracting a first measurement deviation value on the basis of the measurement value corresponding to the reserved resource of the first type UE to obtain a reference measurement value corresponding to the reserved resource of the first type UE.

For example, the obtaining a reference measurement value corresponding to any one of the first resources based on the measurement value corresponding to the any one of the first resources and the second measurement offset value may include: and adding or subtracting a second measurement deviation value on the basis of the measurement value corresponding to any first resource to obtain a reference measurement value corresponding to any first resource.

Exemplarily, taking the measured value as RSRP, when measuring the occupied resource of the first type UE, the reference value of RSRP is considered as RSRP plus an offset value; or, when the first type UE performs measurement, the reference value of RSRP is considered as RSRP obtained by measurement minus an offset value.

Illustratively, the first measurement offset value is predefined or protocol-specified or preconfigured or third carrier-configured or third indication information indicating; and/or the first measurement offset value is related to the CBR of the UE. Wherein the third bearer includes RRC or MAC CE; the third indication information includes: DCI or SCI.

Illustratively, the second measurement offset value is predefined or protocol-specified or preconfigured or fourth bearer-configured or fourth indication information indicating; and/or the second measurement offset value is related to the CBR of the UE. Wherein, the fourth carrier comprises RRC or MAC CE; the fourth indication information includes: DCI or SCI.

In an example, when the UE performs resource detection, if it is detected that the resource corresponding to the received SCI in the resource selection window is a reserved resource of the PUE, RSRP _ beta is accumulated on a measured RSRP result, which is used as a reference RSRP measurement value corresponding to the PUE (that is, RSRP measurement value is RSRP _ real + RSRP _ beta). Meanwhile, the UE acquires RSRP _ th (measurement threshold) according to priorities of the VUE and the PUE and corresponding to a table of priorities configured by RRC and RSRP threshold, compares the RSRP _ real + RSRP _ beta with the RSRP _ th, and excludes reserved resources of the PUE if the RSRP _ real + RSRP _ beta > is the RSRP _ th, otherwise, considers the reserved resources of the PUE as available resources at the current moment.

It should be noted that, in the embodiment of the present application, the first preset rule, the second preset rule, and the third preset rule may be predefined, may also be configured, may also be preconfigured, and may also be configured on the network side, which is not limited in the embodiment of the present application.

Third possible implementation (preference of unoccupied resources for the first type of UE)

Optionally, in this embodiment of the present application, the first resource includes: the reserved resources of the first type of UE and the resources not occupied by the first type of UE. The step 201 may include the following steps 201 b:

step 201 b: and the UE selects all or part of the resources which are not occupied by the first type UE as alternative resources according to the resource information.

Illustratively, the resources unoccupied by the first type of UE include reserved resources of the second type of UE.

Illustratively, in the process of resource selection by the UE, if the resource occupied by the first type UE and the resource occupied by the second type UE exist in the alternative resource set, the resource occupied by the second type UE is preferentially selected.

Exemplarily, the resource information further includes: information indicating that the first probability is lower than the second probability; the first probability is a probability that the UE selects the reserved resource of the first type of UE, and the second probability is a probability that the UE selects the reserved resource of the second type of UE.

For example, the difference between the first probability and the second probability is greater than or equal to a first threshold, where the first threshold is protocol-specified or configured or preconfigured by the control node.

Optionally, in this embodiment of the present application, when the UE is a first type UE, the reporting condition of the alternative resource set is: the ratio of the number of the candidate resource sets to the number of the resources in the resource selection window is greater than or equal to a second threshold.

For example, when measuring the RSRP of the PUE, the reporting condition is that a ratio of the number of resources in the alternative resource set to the number of resources in the resource selection window is greater than or equal to X% (i.e., the second threshold). Wherein the value of X% is less than a value defined in a first protocol version (e.g., R16); in the related art, X% defined in R16 is 20%.

Illustratively, the resource selection method provided by the embodiment of the present invention may further include the following steps:

step A3: and if the alternative resource set meets the preset reporting condition, reporting the alternative resource set.

For example, if the first type UE selects resources, a reporting threshold of an alternative resource set of the first type UE may be defined, and when the alternative resource set satisfies the reporting threshold, the selection process of the alternative resource set is ended, and if the alternative resource set does not satisfy the reporting threshold, the reporting threshold is increased, and resource selection is performed again until the selected alternative resource set satisfies the reporting threshold.

It should be noted that the reporting condition may be predefined, may also be specified by a protocol, may also be configured on the network side, and may also be preconfigured, which is not limited in this embodiment of the application.

Optionally, in this embodiment of the present application, the resource selection method provided in this embodiment of the present application may further include the following steps:

step A4: the UE receives the target signaling.

The target signaling comprises Downlink Control Information (DCI) or Sidelink Control Information (SCI) or high-level configuration signaling; the target signaling is used for indicating that the UE is the first type UE or that the first resource comprises a reserved resource of the first type UE. It will be appreciated that the above-described target signaling is used to mark the first type of UE or to mark reserved resources of the first type of UE.

For example, the target instruction is specifically used to indicate whether the UE is a first type UE or whether the first resource includes a reserved resource of the first type UE.

Illustratively, when a UE receives a special SCI, the SCI may be considered to be the SCI sent by the first type of UE. The special SCI may be an SCI including a special code point.

For example, the indication information carried in the DCI or SCI received by the UE in the resource detection window may be used to indicate whether the UE corresponding to the UE is the first type UE or indicate whether the reserved resource of the UE corresponding to the UE is a resource reserved by the first type UE. Further, the DCI or SCI may display an indication, for example, the DCI or SCI carries 1-bit indication information. The DCI or SCI described above may implicitly indicate, for example, that a predefined code point in the DCI or SCI is represented as scheduling information for a first type of UE.

It should be noted that the target signaling may be configured to the UE by the network side.

Optionally, in this embodiment of the present application, the step 201 may include the following step 201 c:

step 201 c: and the UE determines an alternative resource set according to the target information and the resource information of the first resource in the resource selection window.

Wherein, the target information is used for indicating: the UE selects and/or enables resources, or whether the UE supports a preemption mechanism; the above target information is carried in at least one of: RRC, DCI, SCI, configuration information of the resource pool.

It should be noted that the target information may be configured to the UE by the network side.

Illustratively, the UE enabling refers to enabling the preemption mechanism by the UE.

For example, the UE may determine whether to execute the resource selection scheme provided in the present application for resource selection according to or according to whether the resource pool enables the preemption mechanism, and/or whether the first type UE supports the preemption mechanism.

In one example, RRC pre-configuration or RRC or MAC CE configures whether resources of the first type UE can be preempted.

In another example, DCI or SCI may be used to indicate whether preemption mechanisms are supported/enabled. Further, the DCI or SCI may display an indication, for example, the DCI or SCI carries 1-bit indication information. The DCI or SCI described above may implicitly indicate, for example, that a predefined one or more codepoints in the DCI or SCI indicate that the resource may be preempted, and/or that a predefined one or more codepoints indicate that the resource cannot be preempted.

Illustratively, the target information may be configuration information, which may be a parameter of a resource pool or UE or a priority or BWP or carrier configuration or QoS.

In the resource selection method provided in the embodiment of the present application, when the UE detects the reserved resource of the first type UE and/or the UE is the first type UE, the candidate resource set is determined according to the resource information (at least one of priority information, a measurement result, and a measurement threshold) of the first resource in the resource selection window, and then the target resource is selected from the candidate resource set. Therefore, when the first type UE supports the preemption mechanism or detects that the first type UE is preempted, the first type UE can select or reselect resources based on the resource information of the first resource in the resource selection window, so that the probability of the first type UE that the resources are preempted is reduced, and frequent resource reselection by the first type UE is avoided, thereby reducing the energy overhead and performance loss of the first type UE, and further achieving the purpose of saving power.

Touch panel 1071, also referred to as a touch screen, may collect touch operations by a user on or near the touch panel 1071 (e.g., operations by a user on or near touch panel 1071 using a finger, stylus, or any suitable object or attachment). The touch panel 1071 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 110, and receives and executes commands sent by the processor 110. In addition, the touch panel 1071 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may include other input devices 1072. Specifically, other input devices 1072 may include, but are not limited to, a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, and a joystick, which are not described in detail herein.

Further, the touch panel 1071 may be overlaid on the display panel 1061, and when the touch panel 1071 detects a touch operation thereon or nearby, the touch panel 1071 transmits the touch operation to the processor 110 to determine the type of the touch event, and then the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in fig. 5, the touch panel 1071 and the display panel 1061 are two independent components to implement the input and output functions of the terminal device 100, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the terminal device 100, and is not limited herein.

The interface unit 108 is an interface for connecting an external device to the terminal apparatus 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the terminal apparatus 100 or may be used to transmit data between the terminal apparatus 100 and the external device.

Further, the memory 109 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The processor 110 is a control center of the terminal device 100, connects various parts of the entire terminal device 100 by various interfaces and lines, and performs various functions of the terminal device 100 and processes data by running or executing software programs and/or modules stored in the memory 109 and calling data stored in the memory 109, thereby performing overall monitoring of the terminal device 100. Processor 110 may include one or more processing units; alternatively, the processor 110 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 110.

The terminal device 100 may further include a power supply 111 (such as a battery) for supplying power to each component, and optionally, the power supply 111 may be logically connected to the processor 110 through a power management system, so as to implement functions of managing charging, discharging, and power consumption through the power management system.
