A Quasi-Perfect Resource Allocation Scheme for Optimizing the Performance of Cell-Edge Users in FFR-Aided LTE-A Multicell Networks

A quasi-perfect resource allocation scheme for optimizing the performance of cell-edge users (CEUs) in FFR-aided LTE-A multicell networks (Q-PRAFFR) is proposed, which splits the cell-edge region, cell-edge bandwidth, and CEUs into six parts and allocates the resource to CEUs with the predefined resource allocation priority. Therefore, better performance for inter-cell interference (ICI) coordination is achieved, which results from the more uniform distance distribution among the CEUs allocated with the same bandwidth in different cells. Numerical results show that the outage probability of the fifth-percentile users is dropped by around 70% and the cell throughput is increased by about 10% compared with the state-of-the-art FFR technology.
