1. A communications method, comprising:
obtaining a grouping relationship, wherein 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, the first parameter is related to downlink control information (DCI), a time-frequency resource in each group of time-frequency resources is available for an uplink channel that carries a hybrid automatic repeat request-acknowledgement (HARQ-ACK), and N is a positive integer greater than or equal to 2;
receiving first DCI;
determining, in the 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, wherein i is a positive integer less than or equal to N; 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.
