Abstract
Power control for uplink channels with non-cooperative and rational mobile stations (MS) provided using game theory. As a game leader, a multi-antenna access point (AP) determines the network parameters (bandwidth and the number of receiving antennas) for the power control game played between the mobile stations (MSs) (follower), so as to maximize the network utility per system resource (bandwidth and antennas).

A method for decentralized power control of a multi-antenna access point in a wireless network, the method comprising:
- setting a first plurality of network parameters comprising N, a number of access point antennas, and G, a processing gain;
- receiving a Nash Equilibrium for each of a plurality of mobile stations;
- and calculating a second plurality of network parameters with the received Nash Equilibrium to maximize a long-term revenue function, wherein each mobile station of the plurality of mobile stations is configured to minimize its own transmission power under a minimum transmission rate constraint based on the first plurality of network parameters.
A system for decentralized power control of a multi-antenna access point in a wireless network, the system comprising:
- an access point antenna having a processor programmed to calculate a first plurality of network parameters;
- and a plurality of mobile stations, each of the plurality of mobile stations having a processor programmed to calculate a Nash Equilibrium of a non-cooperative game played by the plurality of mobile stations, wherein the processor of the access point antenna calculates a second plurality of network parameters to maximize a long-term revenue function based on the Nash Equilibrium from the plurality of mobile stations, wherein each mobile station of the plurality of mobile stations is configured to minimize its own transmission power under a minimum transmission rate constraint based on the first plurality of network parameters.
