Location-aided round robin scheduling for fractional frequency reused LTE-A relay network

Relay aided cellular network promises numbers of attractive performances such as cell-edge throughput improvement, fairness enhancement, higher throughput and etc, which is considered in Long-Term-Evolution-Advanced (LTE-A) standard. However, the promised advantages can only be achieved under proper co-channel interference control such as employing Fractional Frequency Reuse (FFR). To overcome the drawback of FFR, we propose a location-aided round robin scheduling algorithm in this paper, which allows the several carefully chosen frequencies to be reused among donor eNodeBs and relay nodes, so as to satisfy the fluctuation of traffic demand.
