Abstract: Provided in the embodiments of the present disclosure are a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback method, a terminal, and a base station. The method comprises: receiving broadcast multicast scheduling signaling sent by a base station, and determining an uplink resource corresponding to unicast; and when it is detected that a preset condition is satisfied, multiplexing a first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling onto the uplink resource corresponding to the unicast, wherein the preset condition is that a HARQ-ACK feedback time slot indicated by the broadcast multicast scheduling signaling and a time slot in which the uplink resource is located exist in a preset window at the same time. In the embodiments of the present disclosure, the design and complexity of a HARQ-ACK protocol for broadcast multicast feedback is simplified.
