This application discloses communications apparatuses, to resolve a problem that joint coding and transmission cannot be performed in a scenario in which PUCCH resources of SRs are not aligned with a PUCCH resource of a HARQ/CSI in time domain. The apparatus is enable to execute comprises: receiving a second UCI on a second PUCCH without receiving a first UCI on the first PUCCH, the first UCI comprising HARQ information, and the second UCI comprising a SR; wherein a time domain position of the second PUCCH overlaps a time domain position of the first PUCCH, a priority of the second UCI is higher than a priority of the first UCI, the priority of the second UCI is a priority of a resource configuration corresponding to the second UCI, and the priority of the second UCI is greater than or equal to a first threshold.
