Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A communications apparatus comprising:
a processor;
a memory coupled to the processor, the memory being configured to store computer-executable instructions; and
wherein the processor is configured to execute the computer-executable instructions stored in the memory, to enable the communications apparatus to perform:
sending a grouping relationship to a terminal device, 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 a time-frequency resource of 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; and
sending first DCI to the terminal device, wherein a first parameter related to the first DCI corresponds to the ith group of time-frequency resources in the N groups of time-frequency resources, and i is a positive integer less than or equal to N.
