【Abstract】 The Institute of Artificial Intelligence D2D communication has the advantages of lower delay, high transmission rate and low power consumption. This paper studies the D2D communication algorithm, establishes the system model, proposes the objective function, and uses the experimental simulation to prove the performance of the proposed algorithm. It focuses on the resource allocation in the D2D communication technology in a single cell, and proposes an algorithm to maximize the system throughput. On the premise of meeting the minimum SINR of CU and DU, It provides D2D users with more choices of spectrum resources and can also improve the utilization of spectrum resources.更多还原
