## Abstract

A method for determining resource multiplexing is provided. The method includes: when it is determined that a first physical uplink control channel (PUCCH) resource of a hybrid automatic repeat request response (HARQ-ACK) of a first type of service and a second PUCCH resource of an HARQ-ACK of a second type of service overlap in a time domain, determining whether the first PUCCH resource and the second PUCCH resource meet a preset timing sequence in the time domain; and if same meet the preset timing sequence condition, then determining performing resource multiplexing processing on the HARQ-ACK of the first type of service and the HARQ-ACK of the second type of service.
