A network entry protocol and an OFDMA symbol allocation scheme for non-transparent relay stations in IEEE 802.16j MMR networks

A relay station (RS) in IEEE 802.16j mobile multi-hop relay (MMR) networks provides access links to far-off subscriber stations (SSs) and hidden subscriber stations. The RS also relays data from a base station and other RSs while maintaining backward compatibility with legacy subscriber stations in existing IEEE 802.16 networks. Much research is being… (More)
