In this paper, we study utility?based resource allocation for us?ers supporting multiple services in a LTE?A system with coor?dinated multi?point transmission for single?user multi?input multi?output (CoMP?SU?MIMO). We designed Joint Transmis?sion Power Control (JTPC) for the selected clusters for mini?mizing power consumption in LTE?A systems. The objective of JTPC is to calculate the optimal transmission power for each scheduled user and subcarrier. Moreover, based on the convex optimization theory, we propose the dynamic sector se?lection method in which the average sector throughput and cell?edge users (UEs) rates are performed to achieve the opti?mal solution. Simulation results show that the system perfor?mance achieved by using the proposed suboptimal algorithm is close to that achieved by the dual decomposition method.
