1. A blind retransmission method, applied to a terminal, the method comprising:
receiving configuration information of blind retransmission sent by a base station; and
performing blind retransmission communication with the base station according to the configuration information,
wherein the configuration information comprises a second timer, during a configured grant communication procedure, after sending uplink new transmission information to the base station and after each blind retransmission of uplink information to the base station, starting the second timer;
during a running period of the second timer, stopping the blind retransmission of the uplink information to the base station, and after expiration of the second timer, performing blind retransmission of uplink information to the base station according to scheduling information of the configured grant;
receiving first indication information sent by the base station;
according to the first indication information, determining a target configured grant suitable for the blind retransmission communication in at least one configured grant; and
in at least one Hybrid Automatic Repeat request (HARQ) process, determining a blind retransmission HARQ process available for the target configured grant according to at least one of an offset or a number of identifiers of HARQs used for the blind retransmission.
