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).
Claims20
A method for decentralized power control of a multi-antenna access point in a wireless network, the method comprising:
- setting network parameters as N, number of access point antennas, and G, processing gain;
- receiving a Nash Equilibrium for each of a plurality of mobile stations;
- and
- calculating network parameters with the received Nash Equilibrium to maximize a long-term revenue function.
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 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 network parameters to maximize a long-term revenue function based on the Nash Equilibrium from the plurality of mobile stations.
A system having a set of single antenna mobile stations transmitting in the same time frequency towards an access point using asynchronous code-division access with a processing gain, the system comprising:
- an access point that maximizes a long-term revenue function which depends on number of antennas and processing gain;
- and
- a set of mobile stations in communication with the access point, the set of mobile stations receiving the number of antennas and processing gain from the access point and each of the set of mobile stations providing a Nash Equilibrium for the long-term revenue function based on the number of antennas and processing gain,
- wherein the access point calculates a number of antennas and processing gain together with the Nash Equlibrium for each of the set of mobile stations that maximize the long-term revenue function.
