Abstract
This disclosure provides a method for receiving a PDSCH and a terminal thereof. The method for receiving a PDSCH includes: after occurrence of a beam failure event is determined, monitoring a PDCCH on a CORESET-BFR and a PDCCH on another CORESET, determining a QCL parameter of the PDSCH based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains DCI scheduling the PDSCH, or a QCL parameter indicated by TCI state information in the DCI scheduling the PDSCH, and receiving the PDSCH based on the determined QCL parameter.

A method for receiving a Physical Downlink Shared Channel (PDSCH), performed by a terminal, wherein the method comprises:
- after occurrence of a beam failure event is determined, monitoring a Physical Downlink Control Channel (PDCCH) on a Control Resource Set for Beam Failure Recovery (CORESET-BFR) and a PDCCH on another CORESET, wherein the CORESET-BFR and the another CORESET are configured for the terminal by a network device;
- and
- determining a Quasi-Colocation (QCL) parameter of the PDSCH based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains Downlink Control Information (DCI) scheduling the PDSCH, or a QCL parameter indicated by Transmission Configuration Indication (TCI) state information in the DCI scheduling the PDSCH, and receiving the PDSCH based on the determined QCL parameter,
- wherein determining a QCL parameter of the PDSCH based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains DCI scheduling the PDSCH, or a QCL parameter indicated by TCI state information in the DCI scheduling the PDSCH comprises:
- determining that the QCL parameter of the PDSCH is the same as the QCL parameter of the PDCCH on the CORESET-BFR.
A terminal, comprising:
- a memory storing computer-readable instructions;
- a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, causes the processor to perform operations comprising:
- after occurrence of a beam failure event is determined, monitoring a Physical Downlink Control Channel (PDCCH) on a Control Resource Set for Beam Failure Recovery (CORESET-BFR) and a PDCCH on another CORESET, wherein the CORESET-BFR and the another CORESET are configured for the terminal by a network device;
- and
- determining a Quasi-Colocation (QCL) parameter of a Physical Downlink Shared Channel (PDSCH) based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains Downlink Control Information (DCI) scheduling the PDSCH, or a QCL parameter indicated by Transmission Configuration Indication (TCI) state information in the DCI scheduling the PDSCH, and receiving the PDSCH based on the determined QCL parameter,
- wherein determining a QCL parameter of the PDSCH based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains DCI scheduling the PDSCH, or a QCL parameter indicated by TCI state information in the DCI scheduling the PDSCH comprises:
- determining that the QCL parameter of the PDSCH is the same as the QCL parameter of the PDCCH on the CORESET-BFR.
A non-transitory computer-readable medium, storing computer-readable instructions that, when executed by a processor, causes the processor to perform operations comprising:
- after occurrence of a beam failure event is determined, monitoring a Physical Downlink Control Channel (PDCCH) on a Control Resource Set for Beam Failure Recovery (CORESET-BFR) and a PDCCH on another CORESET, wherein the CORESET-BFR and the another CORESET are configured for the terminal by a network device;
- and
- determining a Quasi-Colocation (QCL) parameter of the Physical Downlink Shared Channel (PDSCH), based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains Downlink Control Information (DCI) scheduling the PDSCH, or a QCL parameter indicated by Transmission Configuration Indication (TCI) state information in the DCI scheduling the PDSCH, and receiving the PDSCH based on the determined QCL parameter,
- wherein determining a QCL parameter of the PDSCH based on a QCL parameter of the PDCCH on the CORESET-BFR, a QCL parameter of the PDCCH on the another CORESET, a QCL parameter of a PDCCH on a CORESET that contains DCI scheduling the PDSCH, or a QCL parameter indicated by TCI state information in the DCI scheduling the PDSCH comprises:
- determining that the QCL parameter of the PDSCH is the same as the QCL parameter of the PDCCH on the CORESET-BFR.
