Abstract :
As one of the key technologies of LTE-A, relay is main to expand the coverage and improve the throughput of the system. However, two-hop rate matching becomes a bottleneck to improve the resource utilization rate in the relay network. Aiming at this problem, in order to maximize user rate and minimize the transmission power of the system respectively, this paper puts forward an adaptive power allocation strategy which based on two-hop rate matching of LTE-A relay network. The simulation results show the effectiveness of the proposed strategies and demonstrate the superiority over other existing algorithms in the literature.
