We consider the problem of fair resource allocation in interference channels, for the case of one-dimensional cells. We propose simple interference channel models based upon the deterministic channel model, assuming zero queuing delay. This enables study of how the interference induces coupling among the rates available in the channels and evaluation of resource allocation. A sequence of models of...
Relay-assisted communication can improve the quality of service (QoS) of users located at the cell boundary or the shadowed area. In this paper, we investigate the efficient resource allocation scheme for the orthogonal frequency division multiple access (OFDMA) based relaying systems. To maximize system performance, the proposed scheme exploits the spatial reuse in the frequency selective fading...
A novel practical low-complexity multicell orthogonal frequency-division multiple access (OFDMA) downlink channel-assignment method that uses a graphic framework is proposed in this paper. Our solution consists of two phases: 1) a coarse-scale intercell interference (ICI) management scheme and 2) a fine-scale channel-aware resource-allocation scheme. In the first phase, state-of-the-art ICI management...
