Power Allocation in LTE-Advanced Networks S.DEEPA PRINCY Department of Electronics and Communication Engineering National Engineering College Tamil Nadu, India princydeeps@gmail.com P.KAVITHA Department of Electronics and Communication Engineering National Engineering College Tamil Nadu, India Abstract— In this paper considers an LTE-Advanced cooperative cellular networks. LTE Release 8 is one of the primary broadband technologies based on OFDM, which is mainly deployed in a macro/microcell layout. It provides improved system capacity, coverage and seamless integration with existing systems. LTE-Advanced significantly enhances the existing LTE Release 8 and supports much higher peak rates, higher throughput, coverage and lower latencies, which leads to better user experience. Also, LTE Release 10 will support the relay networks. The LTE-Advanced features satisfy the IMT-Advanced requirements. The objective of this work is to improve the cell-edge user’s throughput or to extend the coverage area by placing relays in a cell-edge area. When the channel condition between the eNB and UE is not good, then the cooperative communication takes place .The proposed system used the Type II relay station. To utilize the existing resources effectively the RS and eNodeB transmit in the same channel (In-Band) with decode-and-forward strategy. The power dividing method between eNB and RS is proposed to maximize the achievable rate on each subcarrier. This paper proposes the
