Abstract

Embodiments of the present application provide a data transmission method, device, electronic equipment, and medium, which relate to the field of communication technology. The method includes: the base station monitors the direct transmission data sent by the sending terminal When the transmission link monitors the direct transmission data, it buffers the direct transmission data, and when receiving the reception failure feedback sent by the receiving terminal, sends the direct transmission data to the receiving terminal through the downlink with the receiving terminal. By adopting the application, the reliability of data transmission in the communication system can be improved and the time delay can be reduced.

Description

technical field

[0001] The present application relates to the technical field of communication, and in particular to a data transmission method, device, electronic equipment and medium. Background technique

[0002] At present, in the vehicle wireless communication technology (vehicle to X, V2X), each terminal uses a direct transmission link for data transmission, wherein, V2X includes the long-term evolution (Long Term Evolution, LTE) based on the universal mobile communication technology. V2X and New Radio (NR)-based V2X, NR-based V2X can support more application scenarios, such as: vehicle platoon driving, extended sensing, remote driving, enhanced driving, etc. To meet these services, NR-based V2X needs to support data transmission with higher reliability and lower latency.

[0003] In the prior art, there are two resource allocation methods adopted by NR-based V2X. The first resource allocation method is that the base station centrally allocates transmission resources ...
