Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The resource allocation method provided by the present application can be applied to the application environment shown in fig. 1, where the base station 100 is in communication connection with the user equipment 200. The user device 200 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The base station may be, but not limited to, a macro base station, a micro base station, a small base station, and other types of base station devices, and the base station 100 may be a base station in a 5G network, a Customer Premise Equipment (CPE), and the like, and is not limited herein.

In an embodiment, as shown in fig. 2, a resource allocation method is provided, which is described by taking the application of the method to the base station in fig. 1 as an example, and includes:

s101, determining the physical layer priority of the DG service according to the scene type of the dynamic scheduling DG service; the physical layer priority characterizes a priority degree of the service data processed in the physical layer of the user equipment UE.

The Dynamic Grant (DG for short) service may be an uplink DG PUSCH service scheduled by the base station to the UE through DCI. The scenario type of the DG service may be an eMBB service scenario, a URLLC service scenario, or an eMTC service scenario, which is not limited herein. In an eMB service scene, higher transmission rate can be realized by adopting larger bandwidth and increasing baseband rate, and the eMB service scene is mainly used for services such as high-speed data, high-definition video and the like. In the URLLC service scene, extremely short delay can be realized by pursuing lower delay and higher reliability and by means of faster scheduling, and the method can be used in the scenes of Internet of vehicles, remote control and the like.

The base station can determine the physical layer priority of the DG service according to the corresponding relation between the scene type of the DG service and the physical layer priority. The physical layer priority represents the priority degree of processing the data of each service in the physical layer of the UE, and the UE can determine which service uplink data is preferentially sent according to the physical layer priority of each service.

Optionally, the scenario type of the DG service may be any one of a URLLC service scenario and an eMBB service scenario, and if the scenario type of the DG service is an ultra-reliable low-delay communication URLLC scenario, the base station determines that the physical layer priority of the DG service is a first priority; if the scene type of the DG service is an enhanced mobile broadband eMBB scene, determining that the physical layer priority of the DG service is a second priority; the first priority is higher than the second priority. The first priority and the second priority can be identified by 0 and 1, for example, the first priority is represented by 1, and the second priority is represented by 0; alternatively, the first priority and the second priority may be identified by other types of priority, for example, the first priority is identified by p1, and the second priority is identified by p 0. The specific form of the first priority and the second priority is not limited herein.

S102, sending a downlink control signaling DCI to the UE; the DCI carries the physical layer priority of the DG service; the DCI is used for indicating the UE to perform uplink resource allocation based on the physical layer priority of the DG service and the preset physical layer priority of other services when the DG service conflicts with the uplink resources of other services.

The base station may schedule PUSCH resources of the DG traffic for the UE through the DCI, and indicate physical layer priority of the DG traffic to the UE through the DCI. The base station may select a DCI format matched with the physical layer priority to transmit the DCI according to the physical layer priority of the DG service, or may schedule the DG services with different physical layer priorities by using the same DCI format, which is not limited herein. For example, the base station may schedule DG traffic with low physical layer priority using DCI format0-1, and then schedule DG traffic with high physical layer priority using DCI format 0-2.

The physical layer Priority may be carried in a preset field in the DCI, for example, a Priority field located in the DCI.

After receiving the DCI, the UE may determine, according to the indication in the DCI, a DG PUSCH resource corresponding to a DG service of the UE, and determine whether the DG PUSCH resource conflicts with an uplink resource of another service. The conflict of the uplink resources may refer to a time domain resource conflict or a frequency domain resource conflict.

The other services may be a service in which the UE sends uplink data, or a service in which the UE sends control data; optionally, the uplink resource of the other service includes a CG PUSCH resource of a CG service, and/or a PUCCH resource corresponding to a PUCCH service of the UE. The CG service is a service in which a base station configures resources in advance, and may be, for example, a CG PUSCH service periodically transmitted by the UE to the base station. The PUCCH service may be HARQ-ACK sent by the UE to the base station, or uplink Scheduling Request (SR) sent by the UE to the base station, or Channel Status Information (CSI) sent by the UE to the base station; the type of PUCCH service is not limited herein.

The UE may allocate the uplink resources that have collided according to a preset resource allocation policy, where the resource allocation policy may instruct the UE to allocate the uplink resources based on the physical layer priority of each service, or instruct the UE to allocate the uplink resources based on the physical layer priority of each service and the logical channel priority of each service, which is not limited herein.

When the UE allocates the uplink resources based on the physical layer priority of each service, the allocation result of the uplink resources can be determined according to the physical layer priority of the DG service and other services and the position relationship between the DG PUSCH resources and the uplink resources of other services; or, determining the allocation result of the uplink resource according to the data transmission state of the uplink resource with lower priority of the physical layer; for example, if the uplink resource of the service with low physical layer priority has not started to transmit uplink data, the uplink resource of the service is cancelled, and uplink data transmission of the service with high physical layer priority is guaranteed.

The allocation result of the uplink resource may be the uplink resource for canceling the service with high priority of the physical layer, or the uplink resource for canceling the service with low priority of the physical layer; multiplexing of uplink resources can be realized, and uplink data transmission of DG services and other services is ensured; or, the allocation result of the uplink resource may also be that the data transmission of the service with lower priority of the physical layer is suspended, and after the uplink data transmission of the service with higher priority of the physical layer is completed, the data of the service with lower priority of the physical layer is continuously transmitted; the form of the result of allocating the uplink resource is not limited herein.

In the resource allocation method, the base station determines the physical layer priority of the DG service according to the scene type of the dynamic scheduling DG service; then, sending downlink control signaling DCI to the UE; the physical layer priority represents the priority degree of processing the service data in the physical layer of the User Equipment (UE); the DCI carries the physical layer priority of the DG service; the DCI is used for indicating the UE to perform uplink resource allocation based on the physical layer priority of the DG service and the preset physical layer priority of other services when the DG service conflicts with the uplink resources of other services. The base station determines the physical layer priority of the DG service according to the scene type of the DG service and sends the physical layer priority to the UE through the DCI, so that the UE can perform uplink resource allocation according to the physical layer priority of the DG service and the preset physical layer priority of other services when the DG service conflicts with the uplink resources of other services, thereby avoiding uplink data transmission failure caused by uplink resource conflict and improving the transmission reliability of uplink data.

In an embodiment, on the basis of the foregoing embodiment, the DCI may be specifically used to indicate that when a DG service conflicts with an uplink resource of another service, the UE determines, in the DG service and the other service, a low-priority service with a low physical layer priority, and cancels the uplink resource of the low-priority service when the uplink resource of the low-priority service meets a preset resource cancellation condition.

When the UE detects that the DG service conflicts with the uplink resources of other services, it may determine which service is a low priority service with a lower physical layer priority according to the physical layer priority of the DG service and the physical layer priority of the other services preset in the UE. Further, the UE may determine the uplink resource of the low-priority service according to the resource cancellation condition, and determine whether the uplink resource meets the resource cancellation condition. If the uplink resource of the low-priority service meets the resource cancellation condition, the UE can cancel the uplink resource of the low-priority service, and ensure data transmission of the service with higher priority in the physical layer. If the uplink resource of the low-priority service does not meet the resource cancellation condition, the UE may select the uplink data with the transmission time earlier for transmission according to the time sequence of the uplink resource of the DG service and the uplink resources of other services.

The resource cancellation condition may be that the uplink resource of the low-priority service is cancelled when data is not transmitted in the uplink resource, or that the uplink resource of the low-priority service is cancelled when a time interval between the uplink resource and the current time interval meets a preset condition, and a form of the resource cancellation condition is not limited herein.

The following describes resource allocation manners in several exemplary resource conflict scenarios.

In a resource conflict scenario, if the low-priority service is a DG service, the DCI may indicate that a time interval between a DG PUSCH resource of the DG service and a PDCCH resource where the DCI is located by the UE is greater than a first interval threshold, and determine that the DG PUSCH resource satisfies a resource cancellation condition.

Because the UE needs a certain time to cancel the operation of the uplink resource, when the time interval is too small, the UE considers that the time interval is not enough to complete the operation of canceling the DG PUSCH resource, or the uplink data of the DG service starts to be transmitted before the operation of canceling the DG PUSCH resource is completed, and at this time, the DG PUSCH cannot be cancelled. When the time interval is greater than the first interval threshold, the UE may cancel the DG PUSCH resource and complete data transmission on the PUCCH resource. The first interval threshold T0 may be a fixed value, or may be determined according to the data processing duration of the UE. For example, the T01 may be determined by the fast processing capability parameter Tproc2 of the UE, e.g., the Tprco2 may be 5.5 symbols. T01 ═ Tproc2, T01 ═ Tproc2+ d1, and d1 may be 0 symbols, 1 symbol, or 2 symbols, which is not limited herein. As shown in fig. 3, the time interval between the DG PUSCH resource and the PDCCH resource where the DCI is located is T1, T01 is Tproc2+ d1, and if T1 is greater than T01, the DG PUSCH resource is cancelled.

In another resource conflict scenario, if the low-priority service is a CG service, the DCI is specifically configured to indicate that the time interval between the CG PUSCH resource and the PDCCH resource where the DCI is located is greater than a second interval threshold, and it is determined that the CG PUSCH resource meets the resource cancellation condition.

Because the UE needs a certain time to cancel the uplink resource operation, when the time interval is too small, the UE considers that the time interval is not enough to complete the CG PUSCH resource canceling operation, or before the CG PUSCH resource canceling operation is completed, the uplink data of the CG service has already started to be transmitted, and at this time, the CG PUSCH cannot be canceled. When the time interval is greater than the second interval threshold, the UE may cancel the CG PUSCH resource and complete uplink data transmission on the DG PUSCH resource. The second interval threshold T02 may be a fixed value, or may be determined according to the data processing duration of the UE. For example, the T02 may be determined by the fast processing capability parameter Tproc2 of the UE, e.g., the Tprco2 may be 5.5 symbols. T02 ═ Tproc2, T02 ═ Tproc2+ d2, and d2 may be 0 symbols, 1 symbol, or 2 symbols, which is not limited herein. The second interval threshold may be the same as or different from the first interval threshold.

As shown in fig. 4, the time interval between the CG PUSCH resource and the PDCCH resource where DCI is located is T2, and T02 is Tproc2+ d 2. If T2 is larger than T02, CG PUSCH resources are cancelled, and DG PUSCH data are transmitted; if T2 is less than or equal to T02, CG PUSCH data is transmitted.

In another resource conflict scenario, if the low-priority service is a PUCCH service, the physical layer priority of the PUCCH service is determined by a downlink service corresponding to the PUCCH service; the DCI is specifically configured to instruct the UE to determine that the PUCCH resource satisfies a resource cancellation condition when a time interval between the PUCCH resource and a PDCCH resource of the downlink service is greater than a third interval threshold.

When the time interval is too small, the UE considers that the time interval is not enough to complete the operation of canceling the PUCCH resource, or the PUCCH data has already started transmission before the operation of canceling the PUCCH resource is completed, and the PUCCH resource cannot be canceled. When the time interval is greater than the third interval threshold, the UE may cancel the PUCCH resource and complete uplink data transmission on the DG PUSCH resource. The second interval threshold T03 may be a fixed value, or may be determined according to the data processing duration of the UE. For example, T03 may be T02 ═ Tproc2, or T02 ═ Tproc2+ d3, and d3 may be 0 symbols, 1 symbol, or 2 symbols, which is not limited herein. The third interval threshold may be the same as or different from the first interval threshold and the second interval threshold.

As shown in fig. 5, the PDCCH resource of the downlink traffic corresponding to the PUCCH resource is PDCCH2, the PDCCH resource of the DG traffic is PDCCH1, the time interval between the PUCCH resource and the PDCCH resource of the downlink traffic is T3, and T03 is Tproc2+ d 3. If T3 is larger than T03, canceling PUCCH resources and transmitting DG PUSCH data; if T3 is less than or equal to T03, PUCCH data is transmitted.

In the resource allocation method, the base station indicates the physical layer priority of the DG service through the DCI, so that the UE can determine whether the uplink resource of the low-priority service can be cancelled when the DG service conflicts with the uplink resource of other services, and cancel the uplink resource of the low-priority service when the uplink resource of the low-priority service meets the resource cancellation condition, thereby ensuring the data transmission of the service with high physical layer priority and reducing the uplink data transmission delay of the service with high physical layer priority.

In an embodiment, on the basis of the above embodiment, the DCI is further configured to indicate that the DG service conflicts with the uplink resource of another service, and when the physical layer priorities of the DG service and the other service are the same, the UE implements the uplink resource multiplexing of the DG service and the other service when the uplink resources of the DG service and the other service meet the resource multiplexing condition.

When the UE detects that the DG service conflicts with the uplink resources of other services, it may determine which service is a low priority service with a lower physical layer priority according to the physical layer priority of the DG service and the physical layer priority of the other services preset in the UE. If the physical layer priorities of the DG service and other services are the same, the UE may further determine whether the uplink resource of the DG service and the uplink resource of other services can implement resource multiplexing. If the uplink resources of the DG service and the uplink resources of other services meet the resource multiplexing condition, the UE can perform resource allocation again to realize resource multiplexing. If the uplink resources of the DG service and the uplink resources of other services do not satisfy the resource multiplexing condition, the UE may select the uplink data with the earlier transmission time to transmit according to the time sequence of the uplink resources of the DG service and the uplink resources of other services.

In a resource conflict scene, if other services are PUCCH services, and the physical layer priority of DG services is the same as that of the PUCCH services; the DCI is specifically configured to determine that the PUCCH resource and the DG PUSCH resource of the DG service satisfy the resource multiplexing condition when a time interval between the PUCCH resource and the PDCCH resource corresponding to the PUCCH service is greater than a fourth interval threshold.

Since the UE needs a certain time period to perform the resource multiplexing operation, when the time interval is too small, the UE considers that the time interval is not enough to complete the resource multiplexing operation. When the time interval is greater than the fourth interval threshold, the UE may implement multiplexing of the DG PUSCH resource and the PUCCH resource, for example, transmit PUCCH data through the DG PUSCH resource. And when the time interval is greater than a fourth interval threshold, if the PUCCH resources are tested, the UE firstly sends PUCCH data. The fourth interval threshold may be the same as or different from the third interval threshold.

As shown in fig. 5, the PDCCH resource of the downlink traffic corresponding to the PUCCH resource is PDCCH2, the PDCCH resource of the DG traffic is PDCCH1, the time interval between the PUCCH resource and the PDCCH resource of the downlink traffic is T3, and the fourth interval threshold is T03. If T3 is larger than T03, multiplexing of DG PUSCH resources and PUCCH resources is realized; if T3 is less than or equal to T03, PUCCH data is transmitted.

According to the resource allocation method, the base station indicates the physical layer priority of the DG service through the DCI, so that the UE can realize the uplink resource multiplexing of the DG service and other services under the condition that the uplink resources meet the resource multiplexing condition when the uplink resources of the DG service and other services conflict and the physical layer priorities of the DG service and other services are the same, and simultaneously transmit the uplink data of the DG service and the uplink data of other services, and the transmission reliability of the uplink data of each service is improved.

In one embodiment, on the basis of the above embodiment, the UE further includes a logical channel priority of the DG service, and a logical channel priority of other services; the logical channel priority represents the priority degree of the service data processed in the media access control MAC layer of the UE; the logic channel corresponding to the service with high physical layer priority is high in priority; the DCI is further configured to instruct the UE to process each service data in the MAC layer according to the priority order of the logical channels.

The logical channel priority of the DG service includes a logical channel priority of a URLLC DG service and a logical channel priority of an eMBB DG service, and the logical channel priorities of the other services may include logical channel priorities of CG services, HARQ-ACK, SR, CSI, and other services in a URLLC service scenario and an eMBB service scenario. The logical channel priorities of the services in the same service scenario may be different, for example, for the same service scenario, the logical channel priorities are in turn from high to low: HARQ-ACK, CG PUSCH, DG PUSCH, SR, and CSI.

The priority of the logical channel may be ordered in the same service scenario, or may be ordered uniformly for various types of services in a URLLC service scenario and an eMBB service scenario, which is not limited herein. The logical channel corresponding to the service with the high physical layer priority is high in priority, that is, the logical channel priority of each service in the URLLC service scenario is higher than the logical channel priority of each service in the eMBB service scenario. The priority level of the logical channel can be represented by a number or a priority level, such as a \ B \ C, etc.; when the logical channel priority is represented by a number, the larger the value of the logical channel priority is, the higher the logical channel priority is, or the smaller the value of the logical channel priority is, the higher the logical channel priority is, which is not limited herein.

Fig. 6 shows a correspondence between logical channel priorities and physical layer priorities, where the logical channel priorities corresponding to HARQ-ACK, CG PUSCH, DG PUSCH, SR, and CSI in URLLC service scenario are sequentially 0-4, and the logical channel priorities corresponding to HARQ-ACK, CG PUSCH, DG PUSCH, SR, and CSI in eMBB service scenario are sequentially 8-12; a smaller value of the logical channel priority indicates a higher logical channel priority. The physical layer priorities corresponding to the logical channel priorities 0-4 may be a high priority P1, and the physical layer priorities corresponding to the logical channel priorities 8-12 may be a high priority P0.

The UE can process each service data in the MAC layer according to the priority sequence of the logical channels, can process the data of the service with higher priority of the physical layer preferentially, and avoids the conflict of the priority strategies of the same service data in the physical layer and the MAC layer. For example, when the UE needs to process URLLC CG PUSCH traffic and eMBB DG PUSCH traffic in the MAC layer, the UE may preferentially process URLLC CG PUSCH traffic.

In the above embodiment, the UE may process each service data in the MAC layer according to the priority order of the logical channels, so as to reduce the probability of resource collision of each service data in the physical layer.

Fig. 7 is a schematic flowchart of a resource allocation method in an embodiment, which relates to a manner in which a base station configures a physical layer priority of a service to a UE, and on the basis of the above embodiment, as shown in fig. 7, the method further includes:

s201, determining a resource allocation strategy adopted by the UE when uplink resources conflict according to the enabling states of a physical layer priority switch and a logic channel priority switch configured by a cell network management.

The resource allocation strategy is used for allocating uplink resources when the uplink resources in the UE conflict. Wherein, in the parameters configured by the cell network management, if the physical layer priority switch is enabled, the base station may determine that the physical layer priority can be configured for each service of the UE; if the logical channel priority switch is enabled, the base station may determine that logical channel priorities may be configured for each service of the UE. The base station may determine a resource allocation policy corresponding to the UE according to the enabling state.

Optionally, the resource allocation policy is a first policy or a second policy, and the first policy is determined based on a physical layer priority; the second policy is determined based on the physical layer priority and the logical channel priority; the first strategy represents that the UE can distribute uplink resources in a physical layer according to the physical layer priority of each service, and the second strategy represents that the UE can process each service data in an MAC layer according to the sequence of the logical channel priority and then distribute the uplink resources in the physical layer according to the physical layer priority of each service. If the physical layer priority switch in the cell network management configuration is enabled to be on and the logical channel priority switch is enabled to be off, the base station determines that the resource allocation strategy of the UE is a first strategy. If the physical layer priority switch in the cell network management configuration is enabled to be on and the logical channel priority switch is enabled to be on, the base station determines that the resource allocation strategy of the UE is the second strategy.

S202, according to the resource allocation strategy, sending a Radio Resource Control (RRC) reconfiguration message to the UE; the RRC reconfiguration message carries the enabling state corresponding to the resource allocation policy and the physical layer priority of the CG service.

Further, a Radio Resource Control (RRC) reconfiguration message is sent to the UE according to the Resource allocation policy. The RRC reconfiguration message may carry an enabling state corresponding to the resource allocation policy and a physical layer priority of the CG service. If the resource allocation policy is the second policy, the RRC reconfiguration message further includes the logical channel priorities of the DG service and other services.

If the resource allocation policy is the first policy, the base station may perform RRC configuration for the physical layer priority, and the base station may set the enabling state of the physical layer priority of the DG service through a preset field, for example, set the enabling states of the eMBB DG PUSCH service and the URLLC DG PUSCH service to enabled through fields of a field priority indicator Format dci-Format0-1 and a priority indicator Format dci-Format0-2, respectively. In addition, the base station may also set the physical layer priority of the CG service through a field, for example, the physical layer priority of the CG service may be set through a phy-priority index field in a ConfiguredGrantConfig; the phy-PriorityIndex field is set to p0 for eMBB CG PUSCH traffic and to p1 for URLLC CG PUSCH traffic.

If the resource allocation policy is the second policy, the base station may perform RRC configuration for the physical layer priority and the logical channel priority, respectively. For the physical layer priority, the base station may set the enabling state of the physical layer priority of the DG service through a preset field, for example, the enabling states of the eMBB DG PUSCH service and the URLLC DG PUSCH service are set to enabled through fields of a field priority indicator Format dci-Format0-1 and a field priority indicator Format dci-Format0-2, respectively. In addition, the base station may also set the physical layer priority of the CG service through a preset field, for example, the physical layer priority of the CG service may be set through a phy-priority index field in a ConfiguredGrantConfig; the phy-PriorityIndex field is set to p0 for eMBB CG PUSCH traffic and to p1 for URLLC CG PUSCH traffic. For the logical channel priority, the base station may set the logical channel priority to enable through a preset field, for example, set through lch-base priority in MAC-CellGroupConfig in RRC, and set the field to enable. In addition, the base station may also configure the logical channel priority of each service, and may set the logical channel priority of each service through the priority field in the LogicalChannelConfig, where the value range of the field may be (1.. 16); in addition, the base station may also configure a corresponding relationship between the logical channel priority and the physical layer priority in the RRC, and the specific configuration may be as shown in fig. 6.

When uplink resources of other services of the DG service in the UE collide, the UE may determine whether each service has a physical layer priority and a logical channel priority based on the configuration in the RRC, then specifically obtain a value of each priority according to the RRC and the DCI, and process each service according to the value of each priority.

If the logic channel priority enable state in the RRC is on, the UE may process each service data in the MAC layer according to the logic channel priority order based on the logic channel priority of each service sent by the RRC. If the physical layer priority enable state in the RRC is enable, the UE may obtain the physical layer priority of the DG service in the DCI, and allocate the uplink resource in the physical layer according to the physical layer priority of each service based on the physical layer priority of the CG service sent by the RRC, and the specific allocation process may be as shown in fig. 3-5.

According to the resource allocation method, the base station determines the resource allocation strategy adopted by the UE when uplink resources conflict according to the enabling states of the physical layer priority switch and the logic channel priority switch configured by the cell network management, so that the resource allocation strategy of the UE can be flexibly adjusted according to the configuration; further, the base station sends the RRC reconfiguration message to the UE according to the resource allocation policy, so that when the uplink resource in the UE has a resource conflict, the uplink resource allocation can be explicitly performed based on the resource allocation policy, thereby improving the transmission reliability of uplink data and ensuring data transmission of a service with a higher priority on the physical layer.

In one embodiment, a resource allocation method is provided, which is applied to the user equipment in fig. 1, as shown in fig. 8, and the method includes:
