1. A feedback information transmission method, comprising:
generating, by a first terminal, a sidelink hybrid auto repeat request ACK (HARQ-ACK codebook based on a time domain position of a resource pool of a sidelink channel and a first time-interval set, wherein the sidelink channel includes a physical sidelink shared channel PSSCH) and a physical sidelink feedback channel (PSFCH); and
sending, by a first terminal, the sidelink HARQ-ACK codebook via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) within a target time unit for sending sidelink HARQ-ACK information corresponding to at least one sidelink data, wherein the sidelink HARQ-ACK codebook includes the sidelink HARQ-ACK information,
wherein the sidelink HARQ-ACK information is configured to indicate a receiving state corresponding to the sidelink data, and the sidelink data is physical layer data sent by the first terminal via a sidelink, and
wherein the method further comprises:
receiving the first time-interval set configured via higher layer signaling, wherein the first time-interval set includes a set of offsets ki between a first time slot where an end symbol of the sidelink channel is located and a second time slot where the sidelink HARQ-ACK codebook is fed back, both i and ki being positive integers.
