The research has shown that Coordinated Multi Point (CoMP) transmission can provide significant gains in terms of the overall capacity of cell and cell-edge user throughput. The main purpose of this paper is to enhance the throughput of cell and , the cell-edge user’s, and the fairness among user equipment terminals (UEs) in LTE-Advanced (LTE-A) systems using CoMP In this paper we propose a resource allocation scheme for coordinated multipoint (CoMP). The transmit power is allocated to spatial layer. The transmit power is allocated to spatial layer under the total base station power constraint and the per base station power constraint Keywords : LTE A, CoMP, UE, MIMO, 3GPP Introduction In order to maintain the competitiveness of the 3GPP cellular system, Long Term Evolution (LTE), is developed. For downlink transmission the technique selected is Orthogonal frequency division multiple access (OFDMA). In this time and frequency resources are reused in adjacent cells, inter cell interference becomes the crucial limiting factor. This problem can be overcome by using interference mitigation techniques. The interference mitigation techniques are interference cancellation, interference coordination and the third one is interference randomization currently investigated within 3GPP [1]. However, by using these techniques also the performance or improvements offered by the mitigation techniques are limited since inter cell interference is difficult to remove completely. A
