Power control in a cellular communication system

Method and system for decentralized power control of a multi-antenna access point using game theory

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).

Mobile communications

Base station repeater

Operating a base station repeater having a power control function, the mobile terminal uplink transmit power decreases in response to an increase in signal strength of the uplink signal received at the network, including increasing the gain of the repeater (at 202, Fig. 5) in response to an increase in the uplink signal received above a threshold (Th1) for a time interval (T1), and subsequently decreasing the gain of the repeater (at 204, 206, Fig. 5) until the measured power in the uplink signal received exceeds a threshold (Th1) for a time interval (T1). Due to the power control function, increasing the gain of the repeater causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to decrease. Again, due to the power control function, decreasing the gain of the repeater causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to increase. If the threshold is not exceeded this is indicative of ...

As appropriate for the measurement event which may comprise A2, A3, A4 and A5 as defined in 3GPP TS 36.331 parameters for the threshold(s), offset and signal power or signal quality may be determined.
