基于移动通信系统的车联网通信资源管理

The Resource Management in V2X Communication Based on Mobile Communication System

基于移动通信系统的车联网通信中,无线资源管理是实现有效的车联网通信的关键。车联网通信具有区别于传统移动通信的需求和特征,传统的调度式资源管理或者竞争式资源管理无法满足车联网通信的需求。为了进一步提高车联网通信的资源效率,分析并提出了基于共享资源池的车联网通信资源管理方案,在共享资源池中通过测量并反馈信道使用情况,或者将预占用资源的信息通知给相关节点的方式,形成了协调调度式及竞争式资源管理的综合性车联网资源管理方案,以避免资源使用冲突,达到更高效的车联网资源管理。

For the V2X communication based on mobile communication system,one of the most important key issues is the radio resource management.As there are some different requirements and characters between legacy mobile communication and V2X communication,legacy resource scheduling scheme or contention based resource selection scheme cannot satisfy the requirement of V2X communication.A V2X communication resource scheme based on shared resource pool structure is presented,by using channel status measure and report,or indicating reserved resource information,it can combine scheduling scheme and contention based resource selection into a V2X resource scheme,and it can also avoid potential resource collision and improve the resource efficiency in V2X communication.
