Abstract

A feedback method, device and storage medium for license-free uplink transmission belong to the technical field of communications. The method includes: an access network device receives uplink data sent by a UE in a user equipment group, where the user equipment group includes n UEs, where n is a positive integer; the access network device is in a group public search space corresponding to the user equipment group Send downlink feedback information, where the downlink feedback information is used to indicate the success or failure of uplink transmission of the user equipment group. In the embodiment of the present disclosure, for the authorization-free uplink transmission, a user equipment group is obtained by grouping UEs, and the access network device sends downlink feedback information in the group public search space corresponding to the user equipment group, and indicates the user equipment through the downlink feedback information. Indicates the success or failure of the uplink transmission of the group.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a feedback method, device and storage medium for license-free uplink transmission. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, DCI (Downlink Control Information, downlink control information) is carried by PDCCH (Physical Downlink Control Channel, downlink physical control channel), and the base station sends it to UE (User Equipment, user equipment) ) downlink control information, including uplink and downlink resource allocation information, HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) information, power control information, and the like. [0003] In the LTE system, the HARQ mechanism performs retransmission in units of TB (Transport Block, transport block). The downlink feedback information sent by the base station to the UE includes feedback information corresponding to each TB,...
