Abstract

A communications method, and apparatus are provided, to reduce a transmission latency when a plurality of HARQ-ACKs are transmitted in one time unit. The method includes: determining, in N groups of time-frequency resources based on the grouping relationship, the ith group of time-frequency resources corresponding to a first parameter related to the first DCI, receiving first DCI, and determining a first uplink channel that carries a first HARQ-ACK on a first time-frequency resource in the ith group of time-frequency resources, where the grouping relationship represents a correspondence between a first parameter and N groups of time-frequency resources, the N groups of time-frequency resources are obtained by grouping time-frequency resources in one time unit, each group of time-frequency resources corresponds to one or more first parameters, and the first parameter is related to DCI, a time-frequency resource in each group of time-frequency resources is for an uplink channel carries a HARQ-ACK.
