Research on power control algorithm for 6G oriented D2D communication

The Device to device (D2D) D2D communication as one of the key technologies of 6G has received widespread attention in the industry [1]. Aiming at the problems of single path loss compensation factor and poor power control performance in the 6G small cell network of D2D communication, this paper proposes a compensation factor-based adaptive power control (α -Adaptive Power Control, α -APC) algorithm. According to the D2D users to calculate the distance to the base station and cellular user path loss compensation factor supplement, D2D users and cellular user path loss compensation factor matrix, at the same time further joint power control are adopted to decrease the D2D users and the same frequency interference of cellular subscribers. Experimental simulation shows that compared with recent power control algorithms, This algorithm has a better effect in improving the signal interference plus noise ratio (SINR) system, and compared with the power control algorithm based on the recent increase the throughput of 3.75%.
