Abstract
A method and apparatus for HARQ feedback includes, after receiving a first random access message Msg.A sent by each of at least one terminal, a base station returning a second random access message Msg.B to the at least one terminal. The Msg.B is configured to indicate respective feedback parameters of HARQ feedback terminals in the at least one terminal, and respective HARQ feedback resources of the HARQ feedback terminals are different. The base station receives, on the respective HARQ feedback resources of retransmission terminals, HARQ feedback sent for the Msg.B by the retransmission terminals respectively.

A method for hybrid automatic repeat request (HARQ) feedback, performed by a base station, comprising:
- returning a second random access message Msg.B to at least one terminal after receiving a first random access message Msg.A sent by each of the at least one terminal, wherein the Msg.B is configured to indicate a HARQ feedback resource of each HARQ feedback terminal in the at least one terminal, the Msg.B comprises physical uplink control channel (PUCCH) parameters of respective HARQ feedback terminals, and the HARQ feedback resources of respective HARQ feedback terminals are different;
- and
- receiving a HARQ feedback sent by each HARQ feedback terminal for the Msg.B on the HARQ feedback resource of each HARQ feedback terminal;
- wherein the PUCCH parameters comprise a time parameter k and a PUCCH resource indicator ΔPRI;
- a time point of sending the HARQ feedback is calculated based on the time parameter k, and a serial number of PUCCH resource for sending the HARQ feedback in a PUCCH resource set is calculated based on the PUCCH resource indicator ΔPRIS and the PUCCH resource set is a candidate PUCCH resource set configured by a high signaling.
