1. A communications method, comprising:
receiving, by a communications apparatus, X physical sidelink shared channels (PSSCHs), wherein each one of the PSSCHs corresponds to one respective physical sidelink feedback channel (PSFCH) resource, X PSFCH resources corresponding to the X PSSCHs have a same time domain resource, and X is an integer greater than 1;
determining, by the communications apparatus, M PSFCH resources based on priorities of the X PSFCH resources, transmit powers corresponding to the X PSFCH resources, and a total transmit power of the communications apparatus, wherein M is less than or equal to M′, and M′ is an upper limit of a quantity of PSFCH resources occupied on a first time domain resource;
wherein the M PSFCH resources are determined according to an accumulation result, the accumulation result is obtained by the communications apparatus by accumulating the transmit powers corresponding to the PSFCH resources in descending order of the priorities of the X PSFCH resources; and
sending, by the communications apparatus, feedback information to some or all of the at least one sending terminal on the M PSFCH resources.
