Joint Opportunistic Subchannel and Power Scheduling for Relay-Based OFDMA Networks With Scheduling at Relay Stations

In this paper, we study a joint opportunistic subchannel and power-scheduling problem in relay-based orthogonal frequency-division multiple-access (OFDMA) networks. In most previous works on relay-based networks, immediate relaying at relay stations (RSs) without allowing opportunistic scheduling at RSs was considered. Under this strategy, each RS should… CONTINUE READING
