1. A method for controlling a transmission power of a base station by a remote station in a communication system comprising the steps of:

  • (a) transmitting from said base station a signal over a plurality of links;

    (b) receiving at said remote station said signal over said plurality of links;

    (c) estimating a signal-to-noise ratio (SNR) of said signal for each of said plurality of links;

    (d) determining a power control command as a weighted sum of each of said SNRs;

    (e) transmitting said power control command to said base station; and

    (f) adjusting at said base station said transmission power based on said received power control command.
