Relay selection is a crucial problem for LTE-advanced (LTE-A) networks in order to improve the performance of users in the cell-edge or the hot-spot areas. Relay selection needs to not only consider the distance, the channel quality or the differentiated throughput require of the network, but also take system traffic load into account. It is worth noting that the unbalanced traffic load often degrades...
Intercell interference severely degrades the performance of cell-edge users in cellular networks. To effectively manage the intercell interference, a heuristic scheme that jointly considers user scheduling and power control is proposed for multicell orthogonal frequency division multiple-access (OFDMA) networks with BS cooperation and limited backhaul capacity. First, a greedy user scheduling is proposed,...
