Proportional Fair Allocation for MIMO-OFDMA Based Cellular Relay Networks

P. Rengini, R. Nakkeeran

Abstract


The flexibility in relay networks and Orthogonal Frequency-Division Multiple Access (OFDMA) make the combination a suitable candidate network and air-interface technology for providing reliable and ubiquitous high-data-rate coverage in next-generation cellular networks. The Multiple-Input Multiple-Output based Orthogonal Frequency-Division Multiple Access (MIMO-OFDMA) is a promising high rate air interface technology. It is well known that the throughput and coverage of a system can be significantly enhanced by employing a proper resource allocation (RA) scheme. In this paper, we propose an efficient proportional fair (PF) allocation algorithm for MIMO-OFDMA based cellular relay networks in order to achieve throughput gain and to guarantee fairness at the same time. Numerical results show that, the proposed algorithm can achieve significant improvement on system throughput and fairness of the user throughput for the MIMO-OFDMA based cellular relay networks.
