In the related art, when a base station repeatedly transmits a PDCCH using a plurality of TRPs as a terminal, control resource set pool indexes coresetpoilndex corresponding to a plurality of control resource sets CORESET corresponding to a plurality of search space sets SS set having a link relationship for PDCCH transmission are the same, and configuration information of PDSCHs transmitted by different TRPs does not need to be distinguished. However, when coresetpoilndex corresponding to a plurality of CORESETs corresponding to a plurality of SS sets having a link relationship is different, configuration information of PDSCHs transmitted by different TRPs needs to be distinguished, and in this case, how to configure configuration information of PDSCHs is a problem to be solved.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for configuring a PDSCH of a physical downlink shared channel according to an embodiment of the present disclosure. It should be noted that the method for configuring the PDSCH of the physical downlink shared channel according to the embodiment of the present application is executed by the terminal device. As shown in fig. 1, the method may include the steps of:

step 101, receiving first configuration information, where the first configuration information is used to indicate at least two search space sets SS set having a linking relationship and information of a control resource set CORESET corresponding to each search space set.

Wherein, the CORESETPoolIndex of CORESET corresponding to the at least two search space sets is different.

Having a link relationship means that at least two PDCCH candidate time-frequency resources with the same PDCCH candidate time-frequency resource (PDCCH candidate) index value in at least two search space sets SS set are used to send the same downlink control information DCI. Transmitting the same DCI may be understood as PDCCH repetition transmission.

Optionally, the first configuration information is sent by the network device through radio resource control RRC signaling.

Step 102, determining configuration information of a physical downlink shared channel PDSCH in response to the first configuration information, wherein downlink control information DCI corresponding to the PDSCH is transmitted through at least two PDCCH candidate time-frequency resources in at least two search space sets having a link relationship.

Optionally, the configuration information of the PDSCH includes at least one of dataScramblingIdentityPDSCH, ratemacchpattern, and HARQ-ACK feedback configuration information.

The DCI corresponding to the PDSCH is transmitted through at least two PDCCH candidate time-frequency resources with the same index value in the at least two search space sets with the link relationship indicated in step 101.

Optionally, the configuration information of the PDSCH is determined by receiving RRC signaling.

In some embodiments, the method further comprises: receiving a Control Element (CE, or Control unit) of a first Medium Access Control (MAC) layer, where the Control Element of the first Medium Access Control layer is used to indicate at least one TCI state corresponding to at least one code point corresponding to a transmission configuration indication TCI field in the DCI, and determine that the PDSCH configuration information is PDSCH configuration information corresponding to a specified Control resource set pool index coresetpoolndex.

For example, if the TCI field has 3 bits, the TCI field corresponds to 8 code points, and each code point corresponds to at least one TCI state. Each TCI state may correspond to at least one Quasi Co-location (QCL) Type (Type), wherein the QCL Type includes at least one of Type A, Type B, Type C, and Type D.

Optionally, the coresetpoolndex is assigned to be one of 0,1, and 2.

In some embodiments, in the code points corresponding to the TCI domain, if each code point corresponds to only one TCI state at most, the specified control resource pool index coresetpoolndex is 0 or 1.

In some embodiments, if at least one of the code points corresponding to the TCI domain corresponds to multiple TCI states, the coresetpoolndex is 0,1, or 2.

The configuration information of the PDSCH corresponding to the control resource pool index coresetpoolndex of 2 is configured separately, and is different from the configuration information of the PDSCH corresponding to the control resource pool index coresetpoolndex of 0 or 1.

Further, the control resource set pool index is designated as 2 corresponding to the control resource set pool indexes of the at least two search space sets having a link relation.

That is, the control resource set pool index is separately configured for at least two search space sets having a linked relationship. If there is no independent search space set in the control resource set associated with at least two search space sets having a link relation, the control resource set pool index of this control resource set is also 2. Otherwise, the control resource set pool index for this control resource set is again either 0 or 1. Namely, the index of the control resource set pool is 2, which only aims at the search space set in the control resource set and has a link relation with other search space sets. Wherein an independent search space set refers to a search space set that has no linking relationship with any other search space set.

In an implementation manner of this embodiment, the assigned control resource pool index is determined according to radio resource control RRC signaling or a default rule.

That is, according to the RRC signaling or the default rule, the assigned control resource pool index is determined, and further, the configuration information of the PDSCH is determined to be the configuration information of the PDSCH corresponding to the assigned control resource pool index.

In an implementation manner of this embodiment, the specified control resource set pool index is a control resource set pool index corresponding to a CORESET corresponding to a search space set with a smaller number in at least two search space sets.

That is, of the at least two SS sets having a link relationship, the coresetpoilndex corresponding to the CORESET corresponding to the SS set with the smaller number is used as the specified control resource set pool index.

In an implementation manner of this embodiment, the specified control resource set pool index is a control resource set pool index corresponding to a core set with a smaller core set number in at least two core sets corresponding to the at least two search space sets.

That is, of the at least two CORESET corresponding to the at least two SS sets having a link relationship, the coresetpoilndex corresponding to the CORESET with the smaller CORESET number is used as the specified control resource set pool index.

In an implementation manner of this embodiment, the configuration information of the PDSCH is the configuration information of the PDSCH corresponding to the code point.

Further, second configuration information is received, where the second configuration information is used to determine a control resource set pool index corresponding to each code point in the TCI field, and the configuration information of the PDSCH corresponding to a code point includes configuration information of the PDSCH corresponding to the control resource set pool index corresponding to the code point.

That is, the configuration information of the corresponding PDSCH is determined according to the code point through the association relationship between the code point and the configuration information of the PDSCH. Further, by receiving the second configuration information, determining a coresetpoilndex corresponding to the code point, where the configuration information of the PDSCH corresponding to the code point is the configuration information of the PDSCH corresponding to the coresetpoilndex corresponding to the code point. I.e., the assigned control resource pool index is determined by the codepoint.

It should be noted that all code points corresponding to the TCI field may correspond to the same coresetpoilndex or may correspond to different coresetpoilndex. For example, all 8 code points in the TCI field correspond to coresetpoilndex 0, or code points 000,001,010 correspond to coresetpoinldex 0, code point 011,100,101 corresponds to coresetpoinldex 1, and code points 110,111 correspond to coresetpoinldex 2. Each code point may also correspond to multiple control resource pool indexes, for example, coresetpoolndex corresponding to code point 111 is 0,1 or 1,2, etc.

Optionally, the RRC signaling includes configuration information of the PDSCH corresponding to at least one control resource pool index.

In the embodiment of the present application, the HARQ-ACK feedback configuration information includes an independent feedback configuration or a joint feedback configuration.

Wherein, the independent feedback configuration is used for indicating that PDSCHs corresponding to different control resource pool indexes correspond to different HARQ-ACK codebooks;

the joint feedback configuration is used for indicating that PDSCHs corresponding to different control resource pool indexes correspond to different bit positions of one HARQ-ACK codebook.

It is to be appreciated that the joint feedback configuration can be a joint of HARQ-ACKs corresponding to PDSCH of different control resource set pool indices in part. For example, there are three PDSCHs corresponding to control resource pool indexes 0,1 and 2, the HARQ-ACK feedback of the PDSCHs corresponding to control resource pool indexes 0 and 1 may adopt joint feedback, and the HARQ-ACK feedback of the PDSCHs corresponding to control resource pool indexes 2 adopts separate feedback, that is, the HARQ-ACK feedback of the PDCSH corresponding to control resource pool indexes 0 and 1 adopts different bit positions in the same codebook, and the HARQ-ACK feedback of the PDSCH corresponding to control resource pool index 2 adopts another codebook.

In summary, by receiving first configuration information, where the first configuration information is used to indicate at least two search space sets SS sets with a link relationship and information of a control resource set CORESET corresponding to each search space set, and determining configuration information of a PDSCH (physical downlink shared channel) in response to the first configuration information, where DCI corresponding to the PDSCH is transmitted through candidate time-frequency resources of at least two PDCCH in the at least two search space sets with the link relationship, it is clear that, in a case where coresetpoolndex corresponding to multiple CORESETs corresponding to multiple SS sets with the link relationship is different, a transmission configuration method of the PDSCH is improved, and configuration flexibility of CORESET when the PDCCH is repeatedly transmitted and transmission flexibility of the PDSCH are improved.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for configuring a PDSCH of a physical downlink shared channel according to an embodiment of the present disclosure. It should be noted that the method for configuring the PDSCH of the physical downlink shared channel according to the embodiment of the present application is executed by the terminal device. As shown in fig. 2, the method may include the steps of:

step 201, receiving first configuration information, where the first configuration information is used to indicate at least two search space sets SS set having a linking relationship, and information of a control resource set CORESET corresponding to each search space set.

The first configuration information is used to indicate at least two search space sets having a link relationship and information of a control resource set CORESET corresponding to each search space set SS set.

The coresetpoilndex of CORESET corresponding to the at least two search space sets is different.

In step 202, a first medium access layer control element is received.

Wherein, the first MAC CE is configured to indicate that the transmission configuration in the DCI indicates at least one TCI state corresponding to at least one code point corresponding to the TCI field.

The DCI is transmitted through at least two PDCCH candidate time-frequency resources in at least two search space sets with a link relation, that is, the DCI is the same DCI sent on the PDCCH candidate time-frequency resources with the same PDCCH candidate time-frequency resource index values in the corresponding PDCCH candidate time-frequency resources in at least two search space sets SS sets. Transmitting the same DCI may be understood as repeatedly transmitting the DCI.

Step 203, determining configuration information of the physical downlink shared channel PDSCH.

The PDSCH is a PDSCH correspondingly scheduled by DCI transmitted through at least two PDCCH candidate time-frequency resources in at least two SS sets with a link relation.

The datascramblingidentyipdsch, ratemacchpattern and HARQ-ACK of the CORESET scheduled PDSCH corresponding to different coresetpoilndex need to be distinguished.

In some embodiments, the PDSCH configuration information is determined to be PDSCH configuration information corresponding to a specified control resource set pool index coresetpoolndex.
