Please refer to FIG. 2. FIG. 2 is a flowchart of a method for determining conflicting resources according to an embodiment of the present invention. The method is applied to a terminal. As shown in FIG. 2, it includes the following steps:

Step 201: Determine whether there are conflicting time resources in multiple serving cells of the terminal according to the configuration of the first SS set, where the conflicting time resources refer to different uplink and downlink configurations between different serving cells Time resources.

Wherein, the above-mentioned first SS set may be one or more SS sets. The configuration of the SS set mentioned above may be used to monitor the configuration information of the physical downlink control channel (PDCCH) in the SS set. Of course, this is not limited, for example: SS set resource configuration, switch configuration and other configuration content.

The foregoing multiple serving cells may belong to serving cells of multiple network devices, or may belong to multiple serving cells of the same network device.

The above-mentioned time resources with different uplink and downlink configurations between different serving cells can be that both serving cells are configured as downlink time resources on the same time resource, and other serving cells are configured as uplink time resources, or on the same time resource. Both serving cells are configured for downlink transmission, and other serving cells are configured for uplink transmission. As a result, a half-duplex terminal cannot simultaneously transmit with these multiple serving cells on the time resource, resulting in conflicts.

The foregoing determination of whether there are conflicting time resources 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 of the time resources of the serving cell is determined according to the configuration of the first SS set. And/or transmission type, in this way, the resource type and/or transmission type of the time resource of each serving cell are obtained, so that it can be judged whether there are conflicting time resources in multiple serving cells. That is, the terminal determines whether the uplink and downlink configurations configured by the higher layer signaling configuration on the multiple serving cells conflict with each other according to the first SS set configuration on each serving cell. For example, according to the first SS set, it is determined that the time resource A in the first serving cell is a downlink time resource, and according to the first SS set, it is determined that the time resource A in the second serving cell is an uplink time resource, thereby determining that the time resource A is a conflict Time resources.

In addition, the foregoing determining whether there are conflicting time resources in the multiple serving cells of the terminal may be determining whether there is a conflicting time resource, and determining which time resource the conflicting time resource is.

In the embodiment of the present invention, the time resource can be a symbol, a time slot, a subframe, and so on. Of course, this is not limited. For example, the time resource may be a time resource newly defined in a subsequent agreement, such as a time resource smaller than a symbol.

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

In the embodiment of the present invention, it can be determined whether there are conflicting time resources in the multiple serving cells of the terminal, so that the transmission of the terminal can be selectively transmitted during the conflicting time resources, so as to avoid conflicts and improve the transmission performance of the terminal. Whether the transmission on multiple serving cells can be transmitted, so that the resources on each serving cell can be more fully utilized. In addition, since only the configuration of the first SS set is used to determine whether there are conflicting time resources in the multiple serving cells of the terminal, it is possible to more accurately determine whether there is an uplink-downlink conflict. In addition, the workload of the terminal to determine the conflict time resource can be reduced, so it is not necessary to make judgments based on all SS sets configured by activating the high-level signaling on the downlink BWP.

As an optional implementation manner, the conflict time resource in the first serving cell includes the time resource corresponding to the PDCCH, and the time resource corresponding to the PDCCH is the PDCCH monitoring time resource configured by the first SS set. The serving cell is at least one serving cell among the plurality of serving cells.

The conflicting time resource in the first serving cell may include the time resource corresponding to the PDCCH. The conflicting time resource in the first serving cell may be the time resource corresponding to the PDCCH, and the resource is configured as uplink time in other serving cells. Resource or uplink transmission resource conflict. For example, the time resource A in the first serving cell is configured as a time resource for monitoring the PDCCH, and the time resource A in the second serving cell is configured as an uplink time resource, so that the conflicting time resource includes the time resource A. Of course, the conflict time resource in the first serving cell may include other time resources in addition to the time resources corresponding to the PDCCH. For example, the time resource B in the first serving cell is configured as an uplink time resource, and the second The time resource B in the serving cell is configured to monitor the time resource of the PDCCH, so the conflict time resource includes the time resource B.

The time resource corresponding to the above PDCCH is the PDCCH monitoring time resource configured by the first SS set. The time resource corresponding to the PDCCH may be: the configuration of the first SS set indicates the time resource used for PDCCH monitoring, or the time resource corresponding to the PDCCH The time resource is: the time resource configured for the first SS set for PDCCH monitoring, or the time resource corresponding to the PDCCH is: the time resource for PDCCH monitoring in the first SS set.

In this implementation manner, it can be accurately determined whether the time resource corresponding to the PDCCH is a conflict time resource, so that the reception of the PDCCH can be guaranteed. For example, only the PDCCH is monitored on the time resource and no uplink transmission is performed.

As an optional implementation manner, the above-mentioned time resources with different uplink and downlink configurations between different serving cells include: at least one of a first time resource and a second time resource;

Wherein, in the first time resource, both the configuration of the serving cell is the uplink time resource, and the configuration of the serving cell is the downlink time resource;

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

The foregoing first time resource can be understood as some serving cells configured as uplink time resources, and other serving cells are configured as downlink time resources; the foregoing second time resource can be understood as some serving cells configured as uplink transmission, and other serving cells. Configured as downlink transmission.

In this embodiment, the resource conflicting in uplink and downlink time resources can be determined, and the resource conflicting in uplink and downlink transmission can also be determined. That is, the aforementioned conflict is that on the same time resource, different serving cells are configured with uplink and downlink symbols, or the uplink and downlink transmissions are reversed.

As an optional implementation manner, the first SS set includes at least one of the following:

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

At least one SS set in the SS set group that performs physical downlink control channel PDCCH monitoring;

At least one SS set in the default SS set group;

At least one SS set for which the SS set group identifier is not configured;

The SS set with the shortest period in the group of SS sets monitored by multiple PDCCHs, or the first N SS sets in the group of SS sets monitored by the multiple PDCCHs in order from shortest to longest, where N is an integer greater than 1. .

The at least one SS set corresponding to the SS set group configured on the network side may be one or more SS sets configured with the same SS set group ID (search space set group ID). For example: at least one SS set corresponding to one or more configured SS set group identifiers.

Wherein, the at least one SS set in the SS set group that performs PDCCH monitoring may include: at least one SS set in the SS set group that performs PDCCH monitoring determined according to a PDCCH indication or a timer running state. In this way, it is possible to determine whether there are conflicting time resource bursts in multiple serving cells according to the SS set that actually performs PDCCH monitoring.

The timer may be a timer defined or configured for Search Space Set group switching, or other timers, for example, any one of the following:

drx duration timer (drxOnDurationTimer);

drx inactivity timer drxInactivityTimer;

Radio access conflict resolution timer (ra-ContentionResolutionTimer);

Beam Failure Recovery Timer (beamFailureRecoveryTimer);

Configure the authorization timer (configuredGrantTimer);

Dispatch request prohibit timer (sr-ProhibitTimer);

BPR inactive timer (bwp-InactivityTimer);

Data inactivity timer (dataInactivityTimer);

Secondary cell deactivation timer (sCellDeactivationTimer);

drx downlink retransmission timer (drx-RetransmissionTimerDL);

The drx uplink retransmission timer drx-RetransmissionTimerUL.

At least one SS set in the above-mentioned default SS set group may be an SS set in the search space set group whose network configuration is the default.

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 resources of the cell can be determined according to the SS set corresponding to the serving cell, and then determine Whether there are conflicting time resources in multiple serving cells. Of course, this is not limited, and for each serving cell, the resource type and/or transmission type of the time resource of the cell can be determined according to multiple SS sets, and then it is determined whether there are conflicting time resources in the multiple serving cells.

As an optional implementation manner, the foregoing multiple serving cells include a reference serving cell (reference cell). If the network side configures the conflict time resource in the reference serving cell to perform the set of the first SS When the PDCCH is received, the terminal does not perform uplink transmission of other serving cells on the conflict time resource.

In the embodiment of the present invention, the reference serving cell may be the serving cell with the lowest cell index value in the first frequency band or the first frequency band combination. The first frequency band may be a certain frequency band where the serving cell is located, and the first frequency band combination may be a certain frequency band combination where the serving cell is located. In addition, if there are serving cells that are cross-frequency bands or a cross-frequency band combination exist among the above-mentioned multiple serving cells, there may be multiple reference serving cells.

It should be noted that the reference serving cell may also be referred to as another name, that is, in the embodiment of the present invention, the reference serving cell may also be referred to as a serving cell with 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 serving cell may also be a serving cell defined by a protocol or a network that meets other conditions.

The above-mentioned other serving cells may be serving cells other than the reference serving cell of the above-mentioned multiple serving cells.

In this implementation manner, it can be realized that if on the reference cell, high-level signaling is configured and belongs to the PDCCH of the first SS set, the terminal does not perform these uplink transmissions to ensure priority PDCCH reception.

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

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

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

The above-mentioned flexible time resource may refer to the uplink transmission or downlink resource that can be performed on the time resource, for example, a flexible symbol.

In this way, if the high-level signaling on the reference serving cell is uplink symbols, and the PDCCH configured on other serving cells and belonging to the first SS set is received, the terminal assumes that these symbols are flexible symbols. Thereby improving the transmission flexibility of conflict time resources.

As an optional implementation manner, the above method further includes:

Send instructions;

The indication information is used to indicate to the network whether the terminal has the ability to determine whether to perform uplink transmission of other serving cells according to the first SSSet on the conflict time resource, or the indication information is used to indicate The network indicates whether the terminal has the ability to determine whether the conflicting time resource is a flexible time resource in other serving cells according to the first SS set, and the other serving cell is one of the multiple serving cells except for the reference serving cell. Outside the service area.

The above-mentioned indication information may be sending indication information to the network side to report the above-mentioned capabilities of the terminal to the network side, so that the network side can perform corresponding scheduling and/or transmission according to the capabilities of the terminal. For example, whether the report is capable of determining whether other serving cells can perform uplink transmission according to the first SS Set, or whether the symbols on other serving cells are flexible symbols.

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

Further, the aforementioned capabilities can be used to indicate whether the network can determine at least one of the following according to the first SS set:

Whether other serving cells can perform uplink transmission;

Whether the symbols on other serving cells are flexible symbols.

Specifically, it is determined whether other serving cells can perform uplink transmission on the conflicting time resource, and whether the conflicting time resource is a flexible symbol. Further, if it is not, all RRC configured active DL BWP SS set PDCCHs are determined to be received, for example, PDCCHs are received on all serving cells.

As an optional implementation manner, the above method further includes:

Receive configuration information;

Wherein, the configuration information is used to indicate whether the terminal performs uplink transmission of other serving cells on the conflict time resource, or the configuration information is used to indicate whether the terminal assumes the conflict time in another serving cell The resource is a flexible time resource, and the other serving cells are serving cells other than the reference serving cell among the multiple serving cells.

Whether uplink transmission of other serving cells is performed on the conflict time resource may be: determining whether to perform uplink transmission of other serving cells on the conflict time resource according to the first SS set, and whether the above is in another serving cell Assuming that the conflicting time resource is a flexible time resource may be, according to the first SS set, determining whether to assume that the conflicting time resource is a flexible time resource in other serving cells.

The foregoing configuration information may be configured through RRC signaling, so that the network may configure whether to use the foregoing conflict resource determination method to determine conflict time resources through RRC signaling, and determine at least one of the following according to the first SS set:

Whether other serving cells can perform uplink transmission;

Whether the symbols on other serving cells are flexible symbols;

Specifically, it is determined whether other serving cells can perform uplink transmission on the conflicting time resource, and whether the conflicting time resource is a flexible symbol. Further, if it is not, all RRC configured SS set PDCCHs are determined to be received, for example: PDCCHs are received on all serving cells.

In addition, in the embodiment of the present invention, the network can configure the terminal to receive the channel state indication reference signal (CSI-RS). The CSI-RS can be used for mobility measurement and radio resource management (Radio Resource Management). Management, RRM) measurement, Channel State Information (CSI) measurement, synchronization measurement, etc.

When the terminal is configured with Discontinuous Reception (DRX) at the same time, when the period of DRX is greater than T, for example, when T=80ms, the terminal cannot assume that the CSI configured by high-level signaling is active in DRX time (active time) Others are available; otherwise, the terminal assumes that these CSI-RSs are available.

If the CSI-RS reception configured by RRC is used for the judgment of the uplink and downlink conflicts of the half-duplex terminal in multiple serving cells, the CSI-RS that is not available outside the DRX active time does not perform the judgment of the uplink and downlink conflicts.

If outside of DRX active time, the reference serving cell is configured for CSI-RS reception, and other serving cells are configured with PUCCH/PUSCH/SRS/PRACH transmission by high-level signaling. Only when the DRX cycle is less than T, CSI is required -RS is received, and PUCCH/PUSCH/SRS/PRACH is sent on other serving cells at this time.

In addition, in the embodiment of the present invention, it can be determined whether there is an uplink-downlink configuration conflict with the configuration of other serving cells according to the uplink and downlink transmission configured by high-level signaling. The conflict is caused by the configuration of different serving cells on the same time resource. The uplink and downlink symbols, or the reverse of uplink and downlink transmission. Determine the terminal behavior according to the judgment of the configuration conflict.

However, the uplink (PUCCH/PUSCH/SRS/PRACH) transmission and downlink (PDCCH/PDSCH/CSI-RS) reception of the RRC configuration are usually associated with the configuration of the bandwidth part (Band width Part, BWP), that is, the uplink of terminals on different BWPs. The configuration of sending and downlink receiving may be different. The network can configure multiple BWPs for the terminal, for example, supporting four. When the secondary cell (Scell) is in the active state, the RRC configuration of the activated DL/UL BWP is used to determine whether the uplink and downlink configurations conflict.

However, for deactivated Scells (deactivated Scells), these Scells do not currently activate DL/UL BWP, and it is impossible to determine which BWP is used on the deactivated Scell. The configuration of the uplink transmission and downlink reception of the deactivated Scell determines the conflict behavior.

One solution is to use a certain certain DL/UL BWP uplink transmission and downlink reception configuration to determine the conflict behavior on the deactivated Scell. The DL/UL BWP may include at least one of the following:

The first active downlink BWP (first Active Downlink BWP) and the first active uplink BWP (first Active Uplink BWP) of the serving cell;

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

DL/UL BWP configured by the network to determine the uplink and downlink conflicts between multiple serving cells of half-duplex terminals;

The BWP index is the lowest/highest DL/UL BWP.

In the embodiment of the present invention, PDCCH monitoring can be actually performed according to whether the configured PDCCH search space is actually monitored, and the half duplex transmission and reception behavior can be determined based on the actual monitored PDCCH.

And it can report the UE capability to determine whether the UE has a judgment to determine the transmission and reception behavior of the half duplex according to the SS Set that actually performs PDCCH monitoring.

According to the actual terminal behavior, determine whether the transmission on multiple serving cells can be transmitted, so that the resources on each serving cell can be more fully utilized.

In the embodiment of the present invention, according to the configuration of the first search space set SSset, it is determined whether there are conflicting time resources in the multiple serving cells of the terminal. The conflicting time resources refer to the uplink and downlink between different serving cells. Conflicting time resources. In this way, it can be determined whether there are conflicting time resources in the multiple serving cells of the terminal.

In the embodiment of the present invention, the network can instruct the terminal to perform dynamic search space set switching through the PDCCH, that is, the network configures multiple search space sets through high-level signaling, and then divides the multiple search space sets into multiple groups The search space set group (Search Space Set group), through the PDCCH, instructs the terminal to use the configuration of which search space set group to monitor the PDCCH. The PDCCH may be a group common PDCCH, or other PDCCH, including any PDCCH. In addition to triggering the UE to switch the search space set through the PDCCH, another way is to trigger the switch through the timer (Timer), that is, during the operation of the Timer timer, a set of search space set configurations are used to monitor the PDCCH. When the Timer timer expires, another set of search space sets is used to monitor the PDCCH.

In some technologies, the terminal determines the conflicting time resources for uplink transmission or downlink reception according to all search space sets configured by the network on the activated downlink BWP according to rules. After the dynamic switching of the search space set is introduced, the terminal may only monitor the PDCCH corresponding to a part of the search space set. In this way, if the search space set in which the terminal does not monitor the PDCCH is still included, the terminal may unnecessarily discard transmissions or receptions on some serving cells. However, in the embodiment of the present invention, the conflicting resource determination method described above can determine whether there are conflicting time resources in multiple serving cells of the terminal according to the search space set of the PDCCH monitored by the terminal, and it can further determine whether the conflicting time resources are used for uplink transmission. Or downlink reception.
