摘　　要：为了进一步提高车用无线通信(V2X)技术的资源效率,对于网络侧调度式资源分配的方式,提出了用户设备(UE)上报辅助信息、配置/激活多个半静态调度(SPS)资源的方案;对于UE自主资源选择方式,提出了资源重选和预留的策略。另外,还提出了拥塞控制技术和支持Sidelink载波聚合技术,以分别用来降低资源冲突的概率,达到更高效的车联网资源利用效率。To improve the resource efficiency in vehicle to everything(V2X) communication, the scheme of reporting user equipment(UE) assistant information and configuring/activating multiple semi-persistent scheduling(SPS) resources for network side scheduling resource allocation is proposed in this paper. A strategy of resource reselection and reservation for the UE autonomous resource selection is also proposed. In addition, congestion control technology is proposed to reduce the probability of resource conflict, and Sidelink carrier aggregation technology is supported to achieve more resource utilization efficiency of the V2X communication.
