直通链路技术的发展与展望

Development and prospect of sidelink technology

直通链路技术己广泛应用于车联网场景。对于直通链路技术的潜在技术方向给出可行的建议,包括传统直通链路技术的增强方向,如载波聚合、使用非授权频谱等;侧行链路对于中继场景的应用扩展,包括终端到终端之间的中继,以及中继的多链接场景;在高精度定位场景使用直通链路技术。并且,给出直通链路技术与各种新技术的融合应用,如智能反射面与区块链技术,从而解决直通链路技术自身的缺陷。

Sidelink technology has been widely used in V2X scenarios.The potential technical consideration for Rel-18 feature set will be given out,including the traditional enhancement orientation for traditional sidelink tech-nology,such as carrier aggregation and sidelink-unlisence.The scenario extension for sidelink relay,such as UE to UE relay and multi-connection in relay scenario,the application of sidelink technology in accurate positioning scena-rio.In addition,how to combine sidelink technical with other latest technology was discussed,such as reflective in-telligent surface(RIS)and blockchain technology,to solve its own shortage.
