Description

technical field [0001] The present invention relates to the field of simulation technology, in particular to a D2D communication simulation and performance testing system and method. Background technique [0002] D2D (Device-to-device) communication technology is an emerging technology in the field of mobile communication in the future. It will be gradually obtained, developed and applied in the development process of 5G and even further mobile communication. The basic idea of ​​D2D communication technology is that when a mobile user terminal device is operating on-demand video, downloading files, etc., it first requests and transmits data to other mobile user terminal devices within the D2D communication range, that is, D2D communication. If there is no required data within the range Then request it from the base station in a traditional way. D2D communication can effectively improve the bandwidth utilization of wireless signals and reduce the burden on base stations. Esp...
