In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a method for determining a collision resource according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, determining whether a collision time resource exists in a plurality of serving cells (serving cells) of the terminal according to the configuration of the first SS set, where the collision time resource is: different time resources are configured for uplink and downlink between different service cells.

Wherein, the first SS set may be one or more SS sets. The configuration of the SS set may be configuration information used for monitoring a Physical Downlink Control Channel (PDCCH) in the SS set. Of course, this is not limited, for example: resource configuration, switch configuration, and the like of the SS set.

The plurality of serving cells may belong to serving cells of a plurality of network devices, or may belong to a plurality of serving cells of the same network device.

The time resources with different uplink and downlink configurations between different serving cells may be that, on the same time resource, the serving cell is configured as a downlink time resource, and other serving cells are configured as uplink time resources, or on the same time resource, the serving cell is configured as downlink transmission, and other serving cells are configured as uplink transmission. This results in half-duplex (half duplex) terminals not being able to transmit simultaneously with the multiple serving cells on the time resource, resulting in collisions.

The determining whether the collision time resource exists in the multiple serving cells of the terminal according to the configuration of the first SS set may be that, for each serving cell, the resource type and/or transmission type of the time resource of the serving cell is determined according to the configuration of the first SS set, so that the resource type and/or transmission type of the time resource of each serving cell is obtained, and whether the collision time resource exists in the multiple serving cells can be determined. That is, the terminal determines whether the configured uplink and downlink configurations of the high-level signaling configuration on the multiple serving cells conflict or not according to the first SS set configuration on each serving cell. For example: determining that the time resource A in the first serving cell is a downlink time resource according to the first SS set, and determining that the time resource A in the second serving cell is an uplink time resource according to the first SS set, thereby determining that the time resource A is a collision time resource.

In addition, the above-mentioned determining whether the conflict time resource exists in the plurality of serving cells of the terminal may be determining that the conflict time resource exists and determining which time resource the conflict time resource is.

In the embodiment of the present invention, the time resource may be a symbol, a slot, a subframe, or the like. Of course, this is not limited, for example: the time resource may be a newly defined time resource in a subsequent protocol, such as a time resource smaller than a symbol.

It should be noted that the conflict time resource may be one or more time resources. The terminal may be a half-duplex (half duplex) terminal.

In the embodiment of the invention, whether the conflict time resources exist in a plurality of service cells of the terminal can be determined, so that the transmission of the terminal can be selectively transmitted in the conflict time resources to avoid conflict and improve the transmission performance of the terminal, and whether the transmission in the plurality of service cells can be transmitted can be determined, so that the resources in each service cell can be more fully utilized. In addition, whether the conflict time resources exist in a plurality of service cells of the terminal is determined only according to the configuration of the first SS set, so that whether uplink and downlink conflicts exist can be judged more accurately. In addition, the workload of the terminal for determining the conflict time resource can be reduced, so that the judgment is not required to be carried out according to all SS sets configured by activating high-level signaling on downlink BWP.

As an optional implementation manner, the collision time resource in the first serving cell includes a time resource corresponding to a PDCCH, the time resource corresponding to the PDCCH is a PDCCH monitoring time resource configured by the first SS set, and the first serving cell is at least one serving cell in the multiple serving cells.

The collision time resource in the first serving cell may include a time resource corresponding to a PDCCH, and the collision time resource in the first serving cell is a time resource corresponding to the PDCCH, and the resource is configured as an uplink time resource or a resource collision of uplink transmission in other serving cells. For example: time resource a in the first serving cell is configured to monitor time resources of the PDCCH, and time resource a in the second serving cell is configured as an uplink time resource, such that the conflicting time resource comprises time resource a. Of course, the collision time resource in the first serving cell may include other time resources besides the time resource corresponding to the PDCCH, for example: time resource B in the first serving cell is configured as an uplink time resource, and time resource B in the second serving cell is configured as a time resource for monitoring the PDCCH, so that the conflicting time resource comprises time resource B.

The time resource corresponding to the PDCCH may be a PDCCH monitoring time resource configured for the first SS set, where the time resource corresponding to the PDCCH is: the configuration of the first SS set indicates time resources for PDCCH monitoring, or the time resources corresponding to the PDCCH are: time resources configured for the first SS set and used for PDCCH monitoring, or time resources corresponding to the PDCCH are: time resource for PDCCH monitoring at the first SS set.

In this embodiment, it may be accurately determined whether the time resource corresponding to the PDCCH is a collision time resource, so that the receiving of the PDCCH may be ensured, for example: only the PDCCH is monitored on the time resource, and uplink transmission is not carried out.

As an optional implementation manner, the configuring different time resources for uplink and downlink between different serving cells includes: at least one of a first time resource and a second time resource;

wherein, on the first time resource, the configuration of the serving cell is an uplink time resource, and the configuration of the serving cell is a downlink time resource;

and on the second time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink transmission.

The first time resource may be understood as uplink time resources configured in some serving cells, and downlink time resources configured in other serving cells; the second time resource may be understood as some serving cells configured for uplink transmission and some serving cells configured for downlink transmission.

In this embodiment, the resource of the uplink and downlink time resource conflict may be determined, and the resource of the uplink and downlink transmission conflict may also be determined. That is, the above-mentioned collision is that different serving cells configure uplink and downlink symbols on the same time resource, or uplink and downlink transmissions are opposite.

As an alternative embodiment, the first SS set includes at least one of:

at least one SS set corresponding to the SS set group configured on the network side;

at least one SS set in an SS set group for monitoring a Physical Downlink Control Channel (PDCCH);

at least one SS set of a default set of SS sets;

at least one SS set without configured SS set group identification;

and the shortest period of the SS sets in the SS set groups monitored by the PDCCHs, or the first N SS sets in the SS set groups monitored by the PDCCHs in the period from short to long are sorted, wherein N is an integer larger than 1.

At least one SS set corresponding to the SS set group configured on the network side may be one or more SS sets configured by the network as the same SS set group identifier (search space set group ID). For example: the configured set of one or more SS sets identifies the corresponding at least one SS set.

At least one SS set in the SS set group performing PDCCH monitoring may include: and at least one SS set in the SS set group monitored by the PDCCH is determined according to the PDCCH indication or the running state of the timer. Thus, whether the conflict time resource bursts exist in a plurality of serving cells can be determined according to the SS set actually monitored by the PDCCH.

The timer may be a timer defined or configured for the Search Space Set group switch, or another timer, such as any one of the following:

drx duration timer (drxondurationtimtimer);

a drx inactivity timer drxinactivtytimer;

radio access resolution conflict timer (ra-ContentionResolutionTimer);

a beam failure recovery timer (beamfailure recovery timer);

configuring a grant timer (configuredGrantTimer);

a scheduling request prohibit timer (sr-ProhibitTimer);

a BPR inactivity timer (bwp-InactivetyTimer);

a data inactivity timer (datainactivity timer);

a secondary cell deactivation timer (sCellDeactivationTimer);

a drx downlink retransmission timer (drx-retransmission timerdl);

the drx uplink retransmission timer drx-retransmission timerll.

At least one SS set in the default set group of SS sets may be an SS set in a network-configured default space set group.

It should be noted that, in this embodiment, if the first SS set includes multiple SS sets, for different serving cells, the resource type and/or transmission type of the time resource of the cell may be determined according to the SS set corresponding to the serving cell, so as to determine whether there is a collision time resource in multiple serving cells. Of course, this is not limited, and it may be determined whether there is a collision time resource in a plurality of serving cells after determining the resource type and/or transmission type of the time resource of the cell according to the plurality of SS sets for each serving cell.

As an optional implementation manner, the multiple serving cells include a reference serving cell (reference cell), and if a network side configures PDCCH reception belonging to the first SS set on the collision time resource in the reference serving cell, the terminal does not perform uplink transmission of another serving cell on the collision time resource.

In this embodiment of the present invention, the reference serving cell may be a serving cell with a lowest cell index value in the first frequency band or the first frequency band combination. The first frequency band may be a frequency band in which a serving cell is located, and the first frequency band combination may be a frequency band combination in which the serving cell is located. In addition, if the multiple serving cells have a cross-frequency band or a cross-frequency band combined serving cell, multiple reference serving cells may exist.

It should be noted that the reference serving cell may also be referred to by other names, that is, in the embodiment of the present invention, the reference serving cell may also be referred to as a serving cell of another name. In addition, the reference serving cell is not limited to the serving cell with the lowest cell index value in the first frequency band or the first frequency band combination, for example: the reference cell may also be a protocol or network defined cell that meets other conditions.

The other serving cell may be a serving cell other than the reference serving cell of the plurality of serving cells.

In this embodiment, if the PDCCH configured for the higher layer signaling and belonging to the first SS set is received in the reference cell and the uplink transmission configured for the higher layer signaling is performed in other serving cells, the terminal does not perform the uplink transmission, so as to preferentially ensure the reception of the PDCCH.

Optionally, the uplink transmission includes transmission of at least one of:

a Physical Random Access Channel (PRACH), a Sounding Reference Signal (SRS), a Physical Uplink Shared Channel (PUSCH), and a Physical Uplink Control Channel (PUCCH).

As an optional implementation manner, the multiple serving cells include a reference serving cell, and if the network side configures the collision time resource as an uplink time resource in the reference serving cell and the network side configures the PDCCH belonging to the first SS set on the collision time resource in another serving cell to receive, the terminal assumes that the collision time resource is a flexible time resource in the other serving cell.

The flexible time resource may refer to uplink or downlink resource that may be performed on the time resource, for example: flexible symbols (flexible symbols).

Therefore, if the high-level signaling on the reference serving cell is an uplink symbol, and the PDCCHs which are configured on other serving cells and belong to the first SS set are received, the terminal assumes that the symbols are flexible symbols. Thereby improving the transmission flexibility of the collision time resource.

As an optional implementation, the method further includes:

sending indication information;

the indication information is used for indicating to a network whether the terminal has a capability of determining whether to perform uplink transmission of other serving cells according to the first SS Set on the collision time resource, or the indication information is used for indicating to the network whether the terminal has a capability of determining whether to assume that the collision time resource is a flexible time resource in other serving cells according to the first SS Set, where the other serving cells are serving cells other than the reference serving cell in the plurality of serving cells.

The indication information may be indication information sent to the network side to report the capability of the terminal to the network side, so that the network side may perform corresponding scheduling and/or transmission according to the capability of the terminal. For example: and reporting whether the uplink transmission of other service cells can be determined according to the first SS Set or not, or whether symbols on other service cells are flexible symbols or not.

Further, the UE receives the PDCCH on the collision time resource, and then determines that uplink transmission of other serving cells is not performed on the collision time resource or assumes that the PDCCH is a flexible symbol.

Further, the above capability may be used to indicate whether the network can determine at least one of the following per the first SS set:

whether other serving cells can perform uplink transmission;

whether symbols on other serving cells are flexible symbols.

Specifically, it is determined whether other serving cells may perform uplink transmission on the collision time resource, and whether the collision time resource is a flexible symbol. Further, if not, the PDCCH of SS set of all RRC-configured active DL BWPs determines to receive, for example: the PDCCH is received on all serving cells.

As an optional implementation, the method further includes:

receiving configuration information;

the configuration information is used to indicate whether the terminal performs uplink transmission of other serving cells on the collision time resource, or the configuration information is used to indicate whether the terminal assumes that the collision time resource is a flexible time resource in other serving cells, where the other serving cells are serving cells other than the reference serving cell in the multiple serving cells.

Whether the uplink transmission of the other serving cell is performed on the collision time resource may be determined, on the collision time resource, according to the first SS set, whether the uplink transmission of the other serving cell is performed on the collision time resource, and whether the collision time resource is assumed to be a flexible time resource in the other serving cell may be determined, according to the first SS set, whether the collision time resource is assumed to be a flexible time resource in the other serving cell.

Wherein, the configuration information may be configured through RRC signaling, so that the network may determine the collision time resource by using the collision resource determining method through RRC signaling configuration, and determine at least one of the following according to the first SS set:

whether other serving cells can perform uplink transmission;

whether symbols on other serving cells are flexible symbols;

specifically, it is determined whether other serving cells may perform uplink transmission on the collision time resource, and whether the collision time resource is a flexible symbol. Further, if no, all the PDCCHs of the RRC-configured SS set determine to receive, for example: the PDCCH is received on all serving cells.

In addition, in the embodiment of the present invention, the network may configure the terminal to receive a Channel State indication reference signal (CSI-RS), and the CSI-RS may be used for mobility measurement, Radio Resource Management (RRM) measurement, Channel State Information (CSI) measurement, synchronization measurement, and the like.

When the terminal configures Discontinuous Reception (DRX) at the same time, when the DRX cycle is greater than T, for example, T is 80ms, the terminal cannot assume that CSI configured by higher layer signaling is available outside DRX active time (active time); otherwise the terminal assumes that these CSI-RSs are available.

And if the CSI-RS configured by the RRC receives the information for judging the uplink and downlink conflicts of the half-duplex terminal in a plurality of service cells, the unavailable CSI-RS outside the DRX active time does not judge the uplink and downlink conflicts.

If the reference service cell is configured with CSI-RS receiving outside the DRX active time, other service cells are configured with PUCCH/PUSCH/SRS/PRACH transmitting by high-level signaling, only under the condition that the DRX period is less than T, the CSI-RS is required to receive, and at the moment, the PUCCH/PUSCH/SRS/PRACH is transmitted on other service cells.

In addition, in the embodiment of the present invention, whether a conflict between uplink and downlink configurations exists between the uplink and downlink transmission configured by the high-level signaling and the configurations of other serving cells may be determined, where the conflict is an uplink and downlink symbol configured by different serving cells on the same time resource, or the uplink and downlink transmission is opposite. And determining the terminal behavior according to the judgment of the configuration conflict.

However, uplink (PUCCH/PUSCH/SRS/PRACH) transmission and downlink (PDCCH/PDSCH/CSI-RS) reception configured by RRC are usually associated with configuration of a bandwidth Part (BWP), that is, configurations of uplink transmission and downlink reception of terminals on different BWPs may be different. The network may configure multiple BWPs, for example, support 4 BWPs, and determine whether the uplink and downlink configuration conflicts using the RRC configuration of the activated DL/UL BWP when the secondary cell (Scell) is in an activated state.

However, for deactivating scells (deactivated scells), which do not currently activate DL/UL BWPs, it is not possible to determine which BWP used on the deactivated scells has a configuration determination collision behavior for uplink transmission and downlink reception.

One solution is to use a certain DL/UL BWP configuration to determine the collision behavior on the deactivated Scell. The DL/UL BWP may include at least one of:

a first activation Downlink bwp (first Active Downlink bwp) and a first activation Uplink bwp (first Active Uplink bwp) of the serving cell;

an initial downlink or uplink BWP (initial DL/UL BWP) of the serving cell;

the network is configured with DL/UL BWP for judging uplink and downlink conflicts of a plurality of serving cells of the half-duplex terminal;

BWP indexes lowest/highest DL/UL BWP.

In the embodiment of the invention, the sending and receiving behaviors of the half duplex can be determined by the PDCCH monitored actually according to whether the configured PDCCH search space is used for monitoring the PDCCH actually.

And reporting the capability of the UE, and determining whether the UE determines the judgment of the sending and receiving behaviors of the half duplex according to the SS Set actually carrying out PDCCH monitoring.

According to the actual terminal behavior, whether the transmission on the plurality of serving cells can be carried out is determined, so that the resources on each serving cell can be more fully utilized.

In the embodiment of the present invention, it is determined whether collision time resources exist in multiple serving cells of the terminal according to the configuration of a first search space set SS set, where the collision time resources refer to: time resources for uplink and downlink collisions between different serving cells. This allows determining whether there are conflicting time resources in a plurality of serving cells for the terminal.

In the embodiment of the present invention, the network may instruct the terminal to perform dynamic switching of the Search Space Set (Search Space Set) through the PDCCH, that is, the network configures a plurality of Search Space sets through a high-level signaling, then divides the plurality of Search Space sets into a plurality of Search Space Set groups (Search Space Set groups), and instructs the terminal to monitor the PDCCH by using the configuration of which Search Space Set group through the PDCCH. The PDCCH may be a group common PDCCH, or other PDCCH, including any PDCCH. In addition to triggering the UE to perform the handover of the search space set through the PDCCH, another method is to trigger the handover through a Timer (Timer), that is, monitoring the PDCCH using the configuration of one search space set group during the running period of the Timer, and monitoring the PDCCH using the configuration of another search space set group after the Timer expires.

In some technologies, the terminal performs uplink transmission or downlink reception on all time resources with collision determined by rules according to all search space sets configured on the active downlink BWP by the network. After introducing the dynamic switching of the search space set, the terminal may monitor only PDCCHs corresponding to a portion of the search space set. Thus, if a search space set is still included in which the terminal does not monitor the PDCCH, the terminal may unnecessarily discard transmissions or receptions on some serving cells. In the embodiment of the present invention, the conflict resource determining method can determine whether a conflict time resource exists in a plurality of serving cells of the terminal according to a search space set of the PDCCH monitored by the terminal, and further can determine whether uplink transmission or downlink reception is performed on the conflict time resource.

Referring to fig. 3, fig. 3 is a structural diagram of a terminal according to an embodiment of the present invention, and as shown in fig. 3, a terminal 300 includes:

a determining module 301, configured to determine whether a collision time resource exists in multiple serving cells of the terminal according to configuration of a first search space set SS set, where the collision time resource refers to: different time resources are configured for uplink and downlink between different service cells.

Optionally, the collision time resource in the first serving cell includes a time resource corresponding to a physical downlink control channel PDCCH, the time resource corresponding to the PDCCH is a PDCCH monitoring time resource configured by the first SS set, and the first serving cell is at least one serving cell in the multiple serving cells.

Optionally, the configuring different time resources for uplink and downlink between different serving cells includes: at least one of a first time resource and a second time resource;

and on the second time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink transmission.
