摘要

As one of the key technologies of 5G communication technology, D2D (device to device) communication technology has the advantages of high frequency spectrum efficiency, low energy consumption, low delay, allowing end users to communicate directly through sharing cell resources, at the same time, it will bring Co-Channel interference problems. In order to solve the interference between D2D users and cellular users, and solve the problems of single path loss compensation and poor power control performance. Therefore, a joint power control algorithm based on two factors is proposed. The path loss compensation is calculated according to the distance from user to base station and cellular user, and the path loss compensation factors of D2D users and cellular users are determined. At the same time, the power compensation parameters are introduced to dynamically analyze the user power; The joint power control method is used to reduce the Co- Channel interference of D2D users and cellular users. The experimental simulation shows that: Compared with the traditional power control algorithm, this algorithm improves the signal to interference plus noise ratio (SINR) and throughput of the system.
