Feedback method and apparatus for grant-free uplink transmission, and storage medium

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 comprises n UEs, n being a positive integer;

• and the method comprising:
• 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.

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:
• receive uplink data sent by a user equipment UE in a UE group, wherein the UE group comprises n UEs, n being a positive integer;
• 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.
