Title:
COMMUNICATION FEEDBACK METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/133503
Kind Code:
A1
Abstract:
The present disclosure relates to a communication feedback method and apparatus, a device and a storage medium, which belong to the technical field of communications. The method comprises: determining a target subset in a multicast receiving device set; and sending first control signaling, wherein the first control signaling is used for indicating that a target multicast receiving end in the target subset performs feedback using a first feedback method, and is also used for indicating that other multicast receiving ends outside of the target subset perform feedback using a second feedback method. Signaling overheads can be reduced and feedback resources can be economized; moreover, the problem of communication data loss caused by failing to correctly receive SCI is also effectively avoided, thereby improving transmission reliability.
