Abstract
In a wireless network communications device, transmit power levels may be interactively adjusted to dynamically maintain a desired level of network loading and/or data throughput within the network in a changing network environment.
Claims27
A method, comprising
- performing, within a mobile station in a wireless communications network, operations of:
- transmitting data at a first transmit power level;
- determining a first value for a network traffic parameter at the first transmit power level;
- determining a second transmit power level different than the first power level;
- transmitting data at the second transmit power level;
- determining a second value for the network traffic parameter at the second transmit power level;
- wherein the network traffic parameter is based on a volume of communications observed by the mobile station.

An article comprising
- a machine-readable storage medium that provides instructions, which when executed by a computing platform, cause said computing platform to perform operations comprising:
- transmitting data at a first transmit power level;
- determining a first data throughput value based on transmissions at the first transmit power level;
- transmitting data at a second transmit power level different than the first transmit power level;
- determining a second data throughput value based on transmissions at the second transmit power level;
- and
- setting a subsequent transmit power level at one of the first transmit power level and the second transmit power level, based on a comparison between the first and second data throughput values;
- wherein all the operations of transmitting, determining, and setting are performed within a wireless mobile station.
