基于5G Uu口的车路协同网络能力测试研究

V2X Testing and Research Based on 5G Uu Interface

车联网场景中车路协同是需要突破的关键技术,目前车路协同有PC5和Uu两种技术方案,其中PC5方案RSU部署成本高,4G Uu方案在可靠性及时延等方面难以满足要求。基于5G Uu口开展车路协同网络能力测试研究,包括车路协同2种业务和4类场景,按照6个测试矩阵开展128项测试验证。研究表明在5G组网构架下,V2X业务的RTT达到50 ms以下,满足车路协同业务需求。

The Internet of Vehicles needs to focus on breaking through the technology of V2X.Currently,there are two schemes for V2X:PC5 and Uu interface.The deployment cost of RSU in PC5 scheme is high,and the reliability and latency of the 4G-UU interface scheme cannot meet the requirements.This paper conducts testing and research based on 5G UU port.The content includes 2 types of business,4 types of scenarios and 128 tests.The results indicate that under the 5G network architecture,the RTT of V2X service can reach below 50ms,which can meet the business requirements.
