Due to the shortage of wireless resources and emergence a large number users, determining how guarantee quality-of-service (QoS) requirements users make more work in same spectrum has become an urgent research topic. In this paper, we study multi-user MIMO (MU-MIMO) cellular network system model which (CUs) share resource with multiple device-to-device (D2D) pairs. To maximize admitted D2D pairs sharing CUs, joint power allocation channel gain (JPACG) algorithm is proposed. The optimization problem divided into two steps be solved. First, CUs without Then, transformed minimizing interference when are treated as primary users. admittance order determined by transmission gain. proposed uses convex solve under constraints signal-to-interference-plus-noise ratio (SINR) threshold maximum power. addition, effect on total sum rate all also analyzed. simulation results show that JPACG can achieve better performance admitting
