Classification: CPC H | IPC H

Claim 11:
12. A network-side device, comprising a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the computer program, when executed by the processor, causes the processor to:
send DCI, wherein the DCI is used to indicate cross carrier scheduling a PDSCH;
determine target QCL information of the cross carrier scheduled PDSCH; and
send the cross carrier scheduled PDSCH based on the target QCL information,
wherein, to determine the target QCL information of the cross carrier scheduled PDSCH, the computer program further causes the processor to:
determine 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, determine 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, determine 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, determine 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.
