Methods for downlink power control in wireless communication systems are provided. In response to a transmitter power change request from a mobile terminal () over a wireless connection, a base station () determines a power control parameter based on its current total transmitter power P. The power control parameter preferably relates to a maximum connection-specific transmitter power, a power step size and/or a power increase probability, and is used by the base station to distribute transmitter power pto the connection.

Power control method

A method and system for controlling a transmit power level based upon queue delay for packets in a wireless packet data system is described. Packet data throughput can be improved for selected links based upon queue delay, e.g., those data packets which have experienced a lengthy queue delay can be provided with a higher quality link by increasing their transmit power. The determination of whether or not to prioritize data packets through increased transmit power can be made based upon, for example, a subscriber's QoS profile.
