Claim 9:
10. A feedback method for grant-free uplink transmission, the method being applicable to a target user equipment UE in a UE group, wherein the UE group is obtained by allocating n UEs whose transmission cycles meet a predetermined condition to the same UE group, n being a positive integer, and the predetermined condition comprising: a time interval between transmission cycles of two UEs being less than a first threshold; and the method comprises:
sending, by the target UE, uplink data to an access network device; and
acquiring, by the target UE, downlink feedback information sent by the access network device in a group common search space corresponding to the UE group, wherein the downlink feedback information indicates uplink transmission success/failure of the UE group.
