Abstract:
In this paper we consider distributed power control in a multicell wireless data system and study the e#ect of pricing transmit power. Drawing on our earlier work in [1], we formulate the QoS of a data user via a utility function measured in bits per Joule. We consider distributed power control, modeled as a non-cooperative game, where users maximize their utilities in a multicell system. Base station assignment based on received signal strength as well as received signal-to-interference ratio (SIR) are considered jointly with power control. Our results indicate that for both assignment schemes, such a procedure results in an ine#cient operating point (Nash equilibrium) for the entire system. We introduce pricing of transmit power as a mechanism for influencing data user behavior and our results show that the distributed power control based on maximizing the net utility (utility minus the price) results in improving the Pareto e#ciency of the resulting operating point. Variations of pricing based on global and local loading in cells are considered as a means of improving the e#ciency of wireless data networks. Finally, we discuss the improvement in utilities through a centralized scheme where each base station (BS) calculates the best SIR to be targeted by the terminals it is assigned. 1
