In order to solve the problem of the prior art, embodiments of the present invention provide a channel processing method, apparatus, device, and medium. The following first introduces a channel processing method provided in an embodiment of the present invention.

Fig. 1 shows a flowchart of a channel processing method provided in an embodiment of the present invention, where the method may include:

s101: determining target information corresponding to group-common DCI indication information, wherein the target information comprises TRP or a control resource set CORESET;

s102: and processing the channel according to the indication of the group-common DCI indication information and the target information.

In an embodiment of the present invention, determining target information corresponding to group-common DCI indication information includes:

and determining the CORESET which sends the group-common DCI indication information as the target CORESET.

Illustratively, a plurality of downlink priorities (downlinkpredictions)/transmission power control-physical uplink shared channels (tpc-PUSCH)/transmission power control-physical uplink control channels (tpc-PUCCH)/transmission power control-channel sounding reference signals (tpc-SRS) are configured in the PDCCH-Config IE, and each downlink priority/tpc-PUSCH/tpc-PUCCH/tpc-SRS is associated with a CORESET or a CORESET. If the terminal device detects that group-common DCI transmitted in a CORESET contains a Priority Indicator (PI) or a Transmit Power Control (TPC) command, the terminal determines the CORESET transmitting the group-common DCI as a target CORESET. And then the terminal equipment performs priority processing indicated by the DCI on the PDSCH scheduled by the DCI sent by the CORESET which belongs to the same TRP as the CORESET, or performs power control processing indicated by the DCI on the PUSCH, PUCCH or SRS which belongs to the same TRP scheduling or activation as the CORESET.

For one UE, CORESET1, 2 corresponds to TRP1 and TRP2, respectively, and two tpc-PUSCH1, tpc-PUSCH2 configurations correspond to two CORESETs, respectively.

If the DCI1 sent by the CORESET1 to the UE contains the TPC command of the PUSCH, the UE receives the PUSCH scheduled by the DCI sent by the CORESET1 and performs power control processing according to the configuration of TPC-PUSCH1 and the indication of the DCI 1;

if the DCI2 sent by the CORESET2 to the UE contains the TPC command of the PUSCH, the UE receives the PUSCH scheduled by the DCI sent by the CORESET2 and performs power control processing according to the configuration of the TPC-PUSCH2 and the indication of the DCI 2.

Further illustratively, when one downlink prediction/TPC-PUSCH/TPC-PUCCH/TPC-SRS is configured in the PDCCH-Config to correspond to all the CORESET or CORESET groups, and a plurality of group-common DCI can be configured for the UE, if the terminal device detects that the group-common DCI transmitted in one CORESET includes a Priority Indicator (PI) or a power control (TPC) command, the terminal determines that the CORESET transmitting the group-common DCI is the target CORESET. And then the terminal equipment performs priority processing indicated by the DCI on the PDSCH scheduled by the DCI sent by the CORESET which belongs to the same TRP as the CORESET, or performs power control processing indicated by the DCI on the PUSCH, PUCCH or SRS which belongs to the same TRP scheduling or activation as the CORESET.

Such as: for a terminal device, the CORESET groups {1, 2}, {3, 4, 5} correspond to TRP1 and TRP2, respectively, and one downlink prediction configuration corresponds to a plurality of CORESET groups.

If the DCI1 sent by the CORESET1 to the terminal device includes a downlink PI, the terminal device performs priority processing on the PDSCH according to downlink prediction configuration and the instruction of the DCI1 when receiving the PDSCH scheduled by the DCI2 sent by the CORESET 1/2.

If the DCI3 sent by the CORESET3 to the terminal device includes a downlink PI, the terminal device performs priority processing on the PDSCH according to downlink prediction configuration and DCI3 instructions when receiving the PDSCH scheduled by the DCI4 sent by the CORESET 3/4/5.

and determining the CORESET corresponding to the terminal in the group-common DCI indication information as target information.

Illustratively, an increased bitmap indication in the group-common DCI indicates the corresponding one or more CORESET for the PI or TPC of each terminal device, respectively. And after the terminal equipment receives the group-common DCI, determining the CORESET corresponding to the terminal in the group-common DCI indication information as the target CORESET. And performing priority processing indicated by the DCI on the PDSCH scheduled by the DCI transmitted by the CORESET, or performing power control processing indicated by the DCI on the PUSCH, PUCCH or SRS scheduled or activated by the CORESET.

Such as: for three terminal devices, there are 3 PI indications in the group-common DCI, the increased bitmap is {1, 3, 1}, the PI indication indicating terminal device 1 corresponds to CORESET1 configured for UE1, the PI indication of UE2 corresponds to CORESET3 configured for terminal device 2, and the PI indication of terminal device 3 corresponds to CORESET1 configured for terminal device 3.

Then when terminal device 2 receives the DCI scheduled PDSCH transmitted by the CORESET3 configured for it, it performs priority processing according to the PI indication of the group-common DCI, and does not perform priority processing on DCI scheduled PDSCH transmitted by other CORESET configured for it.

and determining the CORESET corresponding to the terminal in the radio resource control RRC signaling as the target information.

And increasing DCI (configuration group-common) in the RRC signaling to indicate that different terminal equipment correspond to different CORESETs. And the terminal equipment determines the CORESET corresponding to the terminal in the RRC signaling as the target CORESET. And performing priority processing indicated by the DCI on the PDSCH scheduled by the DCI transmitted by the CORESET, or performing power control processing indicated by the DCI on the PUSCH, PUCCH or SRS scheduled or activated by the CORESET.

and determining a plurality of CORESETs as target information.

And when one downlink prediction/tpc-PUSCH/tpc-PUCCH/tpc-SRS is configured in the PDCCH-Config and one group-common DCI is configured for the terminal equipment, the terminal equipment determines a plurality of CORESETs as target CORESETs. And performing priority processing indicated by the DCI on a plurality of DCI scheduled PDSCHs, or performing power control processing indicated by the DCI on a plurality of scheduled or activated PUSCHs, PUCCHs or SRSs.

In one embodiment of the present invention, processing a channel includes:

and processing an uplink channel or a downlink channel according to the indication of the group-common DCI indication information, wherein the uplink channel or the downlink channel is scheduled by CORESET corresponding to the target information.

Fig. 2 shows a schematic diagram of priority indication in a multiple TRP scenario.

The TRP1 sends a PDSCH1 of Enhanced Mobile Broadband (eMBB) service to a UE1, the TRP2 sends a PDSCH2 of eMBB service to a UE1, and the PDSCH1 and the PDSCH2 may have overlapping time-frequency resources. Meanwhile, TRP1 also occupies partial resources in PDSCH1 to send PDSCH1-1 of URLLC traffic to UE 2. Since the URLLC traffic priority is higher, TRP1 sends the PI of the corresponding time-frequency resource through DCI format 2-1 to instruct UE1 to puncture the received PDSCH1 on the indicated time-frequency resource. The CORESET may be determined according to the channel processing method provided in the embodiment of the present invention, and then the priority processing of DCI indication may be performed according to the PDSCH scheduled by the DCI transmitted by the determined CORESET.

According to the channel processing method provided by the embodiment of the invention, the terminal equipment can definitely perform the related processing of group-common DCI indication on the downlink channel or the uplink channel of which TRP is indicated.
