An adaptive resource allocation scheme is proposed for regenerative relay-based orthogonal frequency division multiplexing access systems. This scheme allocates subchannels to guarantee fairness between users, and also saves energy by minimising the transmission power. The subchannel allocation for data rate fairness is considered between direct link users and relay stations in the first time subslot...
In this paper, we propose a resource allocation scheme that limits allocating sub-channels to other cells based on the amount of interference estimated by beacon signals from adjacent cellspsila BSs (base station) to users to reduce the co-channel interference and re-allocates sub-channels to cell-edge users in multi-cell orthogonal frequency division multiplexing access (OFDMA) system. The proposed...
