Claim 0:
1. A method for cross carrier scheduling a physical downlink shared channel, performed by a terminal device, comprising:
receiving downlink control information (DCI), wherein the DCI is used to indicate cross carrier scheduling a physical downlink shared channel (PDSCH);
determining target quasi-colocation (QCL) information of the cross carrier scheduled PDSCH; and
receiving the cross carrier scheduled PDSCH based on the target QCL information,
wherein determining the target QCL information of the cross carrier scheduled PDSCH comprises:
determining a time offset between a receiving moment of the DCI and a receiving moment of the cross carrier scheduled PDSCH;
when the time offset is less than a preset threshold, determining the target QCL information based on predetermined first target TCI state information;
when the time offset is greater than or equal to the preset threshold, and a control resource set (CORESET) corresponding to a physical downlink control channel (PDCCH) carrying the DCI is not configured with a target higher layer parameter tci-PresentInDCI, determining the target QCL information based on predetermined second target TCI state information; and
when the time offset is greater than or equal to the preset threshold, the CORESET corresponding to the PDCCH carrying the DCI is configured with the target higher layer parameter tci-PresentInDCI, and the target higher layer parameter tci-PresentInDCI is set as enabled, determining the target QCL information based on TCI state information in the DCI,
wherein the first target TCI state information and the second target TCI state information are same or different target TCI state information.
