Problems solved by technology

[0006] In the prior art, when two different UEs select the same sub-channel for transmitting the bypass control message SCI, since each UE will use all the control channel resources in the sub-channel for transmission, the SCI transmission of the two UEs will The occurrence of conflicts will have a serious negative impact on the decoding performance, especially when the distance between the two UEs and the receiving end is large, affected by the near-far effect, the signal of the closer UE will completely cover the signal of the far UE, resulting in Unable to solve

Abstract

The invention provides a control information transmission method and device, electronic equipment and a storage medium. The method comprises the steps of determining at least one PSCCH candidate on atleast one selected PSCCH resource during bypass communication; and transmitting the PSCCH on the determined at least one PSCCH candidate. According to the technical scheme provided by the invention,the control channel resource for transmitting the SCI in the V2X resource pool can be fully utilized; when bypass transmission of different UEs uses the same data resource, the conflict degree of control messages between the UEs is reduced, the negative influence of conflicts caused by different UEs on the performance is effectively improved, and the decoding performance of bypass control information is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a control information transmission method, device, electronic equipment, and storage medium. Background technique [0002] In the Long Term Evolution (LTE) technology, bypass communication includes direct device-to-device (D2D) communication and vehicle-to-external communication (Vehicle to Vehicle / Infrastructure / Pedestrian / Network, collectively referred to as V2X). Among them, V2X is designed on the basis of D2D technology. It is superior to D2D in terms of data rate, delay, reliability and link capacity. It is the most representative bypass communication in LTE technology. technology. [0003] In the LTE V2X system, different physical channels are also defined for sidelink communication, including a physical sidelink control channel (PSCCH, Physical Sidelink Control Channel) and a physical sidelink shared channel (P...
