Claim 17:
18. A feedback device for grant-free uplink transmission, the device being applicable to an access network device and comprising:
a processor; and
memory configured to store at least one instruction executable by the processor, wherein
the processor is configured to:
allocate n UEs, whose transmission cycles meet a predetermined condition, to the same UE group, wherein n is a positive integer and the predetermined condition comprises: a time interval between transmission cycles of two UEs being less than a first threshold;
receive uplink data sent by a user equipment UE in the UE group; and
send downlink feedback information 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.
