1. A method, performed by a terminal device or a module in the terminal device, the method comprising:
receiving first downlink control information (DCI) and second DCI, wherein the first DCI indicates a configuration identifier (ID) of a first physical downlink shared channel (PDSCH) that activates the first PDSCH, the second DCI indicates a configuration ID of a second PDSCH that activates the second PDSCH, and the first PDSCH and the second PDSCH are semi-persistent scheduling (SPS) PDSCHs;
determining a first physical uplink control channel (PUCCH) resource corresponding to the first PDSCH, and determining a second PUCCH resource corresponding to the second PDSCH, wherein the first PUCCH resource is used to carry hybrid automatic repeat request (HARQ) feedback information of the first PDSCH, and the second PUCCH resource is used to carry HARQ feedback information of the second PDSCH; and
in response to the first PUCCH resource and the second PUCCH resource overlapping in time domain, and a priority of the first PDSCH being higher than a priority of the second PDSCH, sending, the HARQ feedback information of the first PDSCH through the first PUCCH resource, and cancelling sending the HARQ feedback information of the second PDSCH through the second PUCCH resource, wherein the priority of the first PDSCH is equal to a priority of the HARQ feedback information of the first PDSCH, and the priority of the HARQ feedback information of the first PDSCH is equal to a priority of the first PUCCH; and the priority of the second PDSCH is equal to a priority of the HARQ feedback information of the second PDSCH, and the priority of the HARQ feedback information of the second PDSCH is equal to a priority of the second PUCCH.
