Problems solved by technology
Especially in the NLOS scene test of high-speed curves, due to the high speed, the drivers of the two vehicles cannot perceive each other visually, which is prone to safety problems of the test vehicles and test personnel, resulting in loss of property and life safety
As of now, there is no test method designed for LTE-V2X high-speed curve NLOS scenarios

Embodiment Construction
[0051] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0052] In the prior art, the LTE-V2V performance test method in the high-speed curve NLOS scenario adopts a conventional single two-way high-speed curve NLOS test scenario. figure 1 A schematic diagram showing an NLOS test scene of a single two-way high-speed curve in the prior art. see figure 1 , the NLOS test scenario of a single two-way high-speed curve consists of a curve and at least one occluder. The curve includes two stra...

The invention provides a method and apparatus for testing the communication performance of a wireless terminal. The method is used for realizing an outfield test of the communication performance of anLTE-V2V terminal in a high-speed cornering NLOS scene. Firstly, the high-speed cornering NLOS scene formed by curves and straightaways, which are adjacent to each other is constructed, during the test, a first vehicle and a second vehicle accelerate to specified speeds at specified positions of the curves and the straightaways respectively, and respectively drives along the curves and the straightaways oppositely and evade each other to effectively the collision danger of the two vehicles and ensure the safety of the vehicles and people; and meanwhile, it is ensured that the travelling speedsof the vehicles are large enough to simulate the actual high-speed scene. Secondly, during the travelling of the vehicles, data information of the two vehicles within valid NLOS intervals is collected to serve as test data, thereby ensuring the validity of the test data while effectively avoiding the collision risk, and finally the LTE-V2V communication performance test in the high-speed cornering NLOS scene is achieved safely and effectively at an auxiliary driving stage.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for testing the communication performance of a wireless terminal. Background technique [0002] At the beginning of the 21st century, automobile technology and radio technology showed a trend of mutual integration. The proposal of ITS (Intelligent Transportation System, Intelligent Transportation System) realized the information interaction and fusion between vehicles, pedestrians and roadside infrastructure. With the popularity of LTE (Long Term Evolution, long-term evolution) technology, especially LTE-D2D (Long-Term Evolution Device-to-Device, a communication service that supports communication between devices and devices in LTE cellular systems) The formulation of the standard makes it possible to realize direct communication between vehicles, vehicles, and vehicles based on LTE technology, thereby meeting the low-latency, high-reliability c...
