N2 - In recent years, mobile communication technology has developed rapidly and people have higher requirements for the communication quality. Addressing the problem of low communication quality in areas such as the edge of LTE-A cells, we introduce relay technology to expand the coverage area and improve the communication quality in hotspots. D2D technology can use the increasingly scarce spectrum resources efficiently and improve the utilization efficiency of communication system throughput and frequency band. Using layer 3 relay, we coexist with D2D direct users, D2D non-direct users, and cellular users to construct a communication network, and study the influence of different mode configurations on the throughput. This paper considers the combination of relay technology and D2D technology in the LTE-A cell to study and analyze the communication performance of the system. Based on the LTE-A relay cellular network system architecture and link model and the communication mode of D2D technology, we combine the D2D undirected model with the LTE-A relay cellular network to establish a D2D system model, analyze the communication process, then construct a MINLP optimization problem with system throughput as the objective function and use the method of Lagrange dual to solve it. Through theoretical derivation and simulation analysis, the throughput of the LTE-A cell constructed by the combination of D2D non-direct mode and relay technology is obtained.
