Abstract
A method and apparatus for facilitating power control within mobile radio systems. The power control is a function of location of the mobile station. Power levels are mapped to a geographic grid and power levels are set based upon such pre-determined power levels. Alternatively, initial power levels are set based upon the mapped power levels, but are subject to fine tuning through a much reduced feedback loop.
Claims3
A method for location-based power control within a packet-based mobile radio communications system, said method comprising:
- receiving broadcast power control information on a mobile side of said packet-based mobile radio communications system, said broadcast power control information including a predetermined transmit power level;
- transmitting, at said predetermined transmit power level, a first one-way packet transmission from said mobile side to a network side of said packet-based mobile radio communications system, said first one-way packet transmission including a location data object being a geographical location that corresponds to a portion of a packet-based mobile radio communications coverage area:
- receiving said location data object on said network side;
- matching said location data object to a corresponding power value data object within a power control map of power value data objects;
- and
- in advance of a second one-way packet transmission, re-setting said predetermined transmit power level to said corresponding power value data object.
