Abstract
With the development of 5G technology, the demand for communication quality has shown exponential growth. Regarding the problem of low communication quality at the edge of the LTE-Advanced cellular network, we can expand the coverage and share base station traffic by introducing relay technology and D2D technology, thereby increasing the throughput of the communication system. The research background of this paper is to combine pass-through (direct) D2D mode with LTE-A relay cellular network in LTE-A cells, and then construct the MINLP optimization problem with maximizing system throughput as the objective function. The convex optimization method is used to realize the optimal allocation of power resources. The final simulation results show the growth of system throughput and user fairness.
