Executive Summary

In this paper, the authors propose a new cell architecture for the Orthogonal Frequency Division Multiple Access (OFDMA) systems by jointly taking Frequency Allocation Scheme (FAS) and cooperative relay strategy into consideration. To serve the Mobile Stations (MSs) in the inner zone and Relay Stations (RSs) in the outer zone, a larger portion of frequency spectrum is allocated to the central Base Station (BS) such that the transmission from BS to RSs can never be a bottleneck during the two-hop relay process.
