Abstract

The present disclosure relates to a communication feedback method, apparatus, device, and storage medium, and belongs to the field of communication technologies. The method includes: determining a target subset in the set of multicast receiving devices; and transmitting first control signaling, wherein the first control signaling is used to indicate that the target multicast receiving end in the target subset is performed by using a first feedback manner, and is further used to indicate that other multicast receiving ends other than the target subset are fed back by using a second feedback manner. The signaling overhead can be reduced, the feedback resources are saved, and the problem of loss of communication data due to incorrect reception of the SCI is effectively avoided, and the transmission reliability is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and specifically relates to a communication feedback method, device, device and storage medium. Background technique [0002] With the continuous development of wireless communication technology and Internet of Vehicles communication technology, the current wireless communication system can support direct communication between devices. The direct connection communication method has the characteristics of short delay and small signaling overhead, and is very suitable for communication between devices and other surrounding devices. The direct connection communication mode also supports multicast communication and a HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) mechanism, that is, the HARQ mechanism can be implemented when the sending end performs multicast communication with multiple receiving ends. [0003] The multicast sender sends communication data to ...
