An opportunistic power control algorithm for cellular network

Published: 01 June 2006 Publication History

Abstract

We propose an opportunistic power control algorithm, which exploits channel fluctuation in order to maximize system throughput. The basic idea is that it instructs a transmitter to increase its power when the channel is good and to decrease its power when the channel is bad. The transmission rate is adjusted according to the received signal-to-interference ratio. The proposed algorithm is distributed and can be applied to systems in which the transmitters are connected to different receivers. We prove that the algorithm always converge to a unique fixed point and thus is stable. Simulation results show that a tremendous increase in system capacity can be achieved, when compared with other power control algorithms. Furthermore, the algorithm works well for nonreal-time terminals when other real-time terminals employ the target-tracking power control. It can also be extended to cases where maximum power constraint is imposed and soft handoff is executed.

Leung and Sung introduce a new concept, opportunistic power control (OPC), to overcome the interference problem in communication channels. The traditional approach for overcoming this problem has been target tracking, which means that transmission power is increased when the signal fades. Under the OPC approach, high power is used when the channel has less interference, and low power is used at times of interference. The authors claim a ten-fold throughput increase in their simulation when compared to target tracking. Another important contribution of this paper concerns the distributed nature of control in performing OPC. In a cellular network, transmission needs vary, and are not well suited to having a central power controller make power augmentation decisions. The OPC approach enables adjustments in transmission power based on feedback from the various receivers on the network. To ensure adequate bandwidth for all the cells, the authors introduce a fairness principle. This is illustrated using a five-user single-cell system. Even though this paper describes a different approach to solving the power control problem, the method described is suitable only for applications that are not sensitive to time delay. Thus, a cellular network with primarily mobile phone service would benefit from the target tracking method as opposed to the OPC method. The paper includes several theorems using mathematical concepts from measure theory. These theoretical results enable the authors to conclude that their algorithm converges to a unique fixed point, and thus provides the necessary stability for practical applications.
