摘要：

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 cells' 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 scheme can improve the outage probability that users don't achieve the required rate. The computer simulation shows that the proposed scheme can provide better system utilization and outage probability performance compared with the conventional scheme.
