Abstract :
We present a novel static power control scheme to improve system capacity in wireless cellular networks. Our basic idea is to reduce intercellular interference and improve the capture probability by coordinating transmission powers of users in different cells. This coordination is determined beforehand and no real-time coordination is required. Power control is static and fixed. We formulate and solve a generic optimal scheduling problem with our coordination scheme. We find that the optimal scheduling policy is in a simple form of bang-bang control, which is illustrated for a specific case with the uniform fairness constraint. We evaluate, via numerical analysis and simulation, both throughput and delay, and compare them with other schemes. We find that the coordination scheme can achieve significant performance improvement, in terms of both maximum throughput and throughput-delay tradeoff, over a wide range of capture ratio values
