Abstract

Relay enhanced cellular (REC) system and orthogonal frequency division multiple access (OFDMA) technology are regarded as the key features of 4G communication systems. How to utilize resource wisely in OFDMA-based REC systems is an important and challenging research topic. This paper reviews the major issues in designing radio resource management (RRM) algorithms for REC systems. A new resource allocation algorithm is proposed with joint considerations on fairness, resource balancing, resource reuse, and multi-user diversity.
