An Interference Detection Method for Mobile Relay Stations in Transparent Mode of IEEE 802.16j Mobile Multi-Hop Relay Networks

As an evolution of IEEE 802.16e, IEEE 802.16j Mobile Multi-hop Relay (MMR) have been studied for user throughput improvement, coverage extension and/or capacity enhancement. In particular, the introduction of mobile Relay Station (RS) is expected to enable public transportation such as a bus or subway to provide the improved wireless Internet service. However, because the mobile RS randomly moves in all directions, it may generate severe interference and degrade the performance of the service. For that reason, an interference detection method is required in order to realize the introduction of the mobile relay station. In this paper, the authors propose an interference detection method using the transparent mode in IEEE 802.16j mobile multi-hop relay networks.
