It has been shown that, with the instantaneous power constraint and joint power allocation, two-way relaying (TWR) outperforms one-way relaying (OWR) in terms of system throughput. However, the conclusion is not clear for the case with the average power constraint and the case with the instantaneous power constraint but separate power allocation. In this paper, we shall first investigate the optimality...
We design a low-complexity solution to multi-layer optimization in multi-hop wireless networks with throughput objectives. Considering channel sensing and power control at the physical layer, we formulate resource allocation as a non-convex throughput optimization problem that allows distributed implementation. We develop a genetic algorithm to solve this physical layer problem with local information...
In this paper, we consider downlink communication in multicell systems with each cell containing one base station (BS) and multiple mobile stations (MS). Full frequency reuse is assumed allowing the BSs to transmit simultaneously over the same frequency band. We propose a power control algorithm to minimize the impact of intercell interference and maximize the system overall throughput. The proposed...
