V2V实测通信数据

V2V通信数据的采集主要分为间接通信测试（通过RSU中继）、直接通信测试（基于PC5直连接口）和紧急场景测试三个阶段。在间接通信测试中，动态测试场景通过RSU转发消息实现车辆间通信，重点采集中继通信的端到端时延与丢包率，以及多车同时通信时的吞吐量限制。这一阶段的目的是验证多车协同场景下通信链路的稳定性，尤其是在复杂道路环境中的适应性。直接通信测试基于3GPPRelease14PC5接口，在特定场中模拟车辆盲区通信。通过OBU间直接传输SPAT/MAP消息，采集直连通信的吞吐量与时延，以及盲区场景下的信号强度与通信成功率。

The collection of V2V communication data is mainly divided into three stages: indirect communication test (via RSU relay), direct communication test (based on PC5 direct interface), and emergency scenario test. In the indirect communication test, a dynamic test scenario is established to achieve vehicle-to-vehicle communication by forwarding messages through RSU, focusing on collecting the end-to-end delay and packet loss rate of relay communication, as well as the throughput limit when multiple vehicles communicate simultaneously. The purpose of this stage is to verify the stability of communication links in multi-vehicle cooperative scenarios, especially its adaptability in complex road environments. The direct communication test is based on the 3GPP Release 14 PC5 interface, which simulates vehicle blind spot communication in specific scenarios. By directly transmitting SPAT/MAP messages between OBUs, this test collects the throughput and delay of direct communication, as well as the signal strength and communication success rate in blind spot scenarios.
