Uplink Transmission Method and Communication Apparatus

A method, performed by a terminal device or a module in the terminal device, comprising:

• receiving first downlink control information (DCI) and second DCI, wherein the first DCI comprises a configuration identifier (ID) of a first physical downlink shared channel (PDSCH) that activates the first PDSCH, the second DCI comprises 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 priority of the first PDSCH according to the configuration ID of the first PDSCH, and determining a priority of the second PDSCH according to the configuration ID of the second PDSCH;
• 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
• when the first PUCCH resource and the second PUCCH resource overlap in time domain, and the priority of the first PDSCH is higher than the 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.

An apparatus comprising:

• one or more processors;
• and
• a non-transitory computer readable medium storing instructions that, when executed by the one or more processors, cause the apparatus to:
• send first downlink control information (DCI) and second DCI, wherein the first DCI comprises a configuration identifier (ID) of a first physical downlink shared channel (PDSCH) that activates the first PDSCH, the second DCI comprises 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, and wherein there is a correspondence between the configuration ID of the first PDSCH and a priority of the first PDSCH, and there is a correspondence between the configuration ID of the second PDSCH and a priority of the second PDSCH;
• determine a first physical uplink control channel (PUCCH) resource corresponding to the first PDSCH, and determine 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
• when the first PUCCH resource and the second PUCCH resource overlap in time domain, and the priority of the first PDSCH is higher than the priority of the second PDSCH, receive the HARQ feedback information of the first PDSCH through the first PUCCH resource, and cancel receiving the HARQ feedback information of the second PDSCH through the second PUCCH resource.
