Abstract
Disclosed are a hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback method, a terminal, and a base station. The method includes: transmitting broadcast multicast scheduling signaling to a terminal for indicating the terminal to multiplex, when it is detected that a preset condition is satisfied, a first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling on the uplink resource corresponding to unicast, the preset condition being that both a HARQ-ACK feedback slot indicated by the broadcast multicast scheduling signaling and a slot in which the uplink resource is located exist in a preset window; and receiving uplink data transmitted by the terminal through the uplink resource when the preset condition is satisfied, and obtaining a first HARQ-ACK codebook multiplexed on the uplink resource. The protocol design and complexity of HARQ-ACK feedback for broadcast multicast is simplified.
