Dynamic Radio Resource Management for OFDMA-Based Relay Enhanced Cellular Network

Relay technology is one of the technologies that will enhance user experience in the next generation cellular networks. One of the goals (and characteristics) of successful cellular network design is availability of services to all subscribed users irrespective of their location. Designing a good Radio Resource Management (RRM) is essential in achieving that goal. In this paper we propose a dynamic resource partitioning in the OFDMA-based Relay Enhanced Networks. We study performance of the proposed RRM scheme with fairness and maximum throughput objectives and show that it has superior performance in comparison with conventional RRM schemes.
