Resource allocation in multicell downlink orthogonal frequency division multiple-access (OFDMA) systems is investigated, where base stations (BSs) first independently carry out subcarrier allocation and then mitigate intercell interference (InterCI) with the aid of very limited BS cooperation. Two novel InterCI mitigation algorithms are proposed. The first one is the distributed decision making assisted...
For the overlaid HDD cellular system, where TDD and FDD coexist in the inner region, we suggest a new frame structure adopting partial frequency reuse (PFR). We found that the overlaid HDD system with PFR outperforms other conventional systems by the optimal downlink power allocation. We also found that cooperative transmission with network coding improves the capacity of the cell border in the overlaid...
We consider wireless telecommunications systems with orthogonal frequency bands, where each band is referred to as a channel, e.g., orthogonal frequency-division multiple access (OFDMA). For a given snap-shot in time, two joint channel assignment and power allocation optimization problems are presented, one in downlink and one in uplink. The objective is to maximize the minimum total Shannon capacity...
