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.
