Throughput-Guaranteed Resource-Allocation Algorithms for Relay-Aided Cellular OFDMA System |
Abstract | ||
|---|---|---|
Radio resource allocation for the Downlink (DL) transmissions in a cellular system, based on Orthogonal Fre- quency Division Multiple Access (OFDMA), has been subject of many research studies over the past years. Nowadays, increasing attention is turned upon cellular system with relays, but only few algorithms have been designed for OFDMA based relay system. In this work, resource allocation schemes are proposed for the cases of one and multiple Relay Stations (RS) in the cell. Due to the specific design of these algorithms, which operate in a RS-aided BS centralized manner, the amount of required Channel State Information (CSI) and algorithm complexity are minimized, making them suited for practical use. The idea of adaptive RS activation is introduced, where the frame structure is adapted depending on the active RS. Different number of relays are considered and the corresponding algorithms are adapted accordingly. The simulation results show that our algorithms achieve a very good throughput/outage trade-off. |
