1. A method of controlling forward and reverse link channel transmission power, Ptransmit, to and from a user terminal in a wireless communications system having a plurality of beams, comprising the steps of:

  • (a) receiving an in-use formatted message signal to noise ratio (SNR) of an active signal of interest;

    (b) determining a baseline power level, Pbaseline, from the received active formatted message SNR, wherein the determining step comprises calculating a transmit power level offset;

    (c) identifying an interference susceptibility of the active signal of interest comprising the step of measuring a signal power of at least one adjacent signal at a receiver;

    (d) transmitting a formatted interference message comprising segregating interference susceptibility into categories detected at the receiver;

    (e) determining a power margin, Pmargin, from the identified interference susceptibility;

    (f) identifying a quality of service metric (QSM) associated with the active signal of interest;

    (g) determining a power level correction factor, Pcorrection, based on the QSM;

    (h) identifying a signal fade condition associated with the active signal of interest;

    (j) determining a fade margin power level Pfade, based on the signal fade condition; and

    (k) setting Ptransmit based on Pbaseline, Pmargin, Pcorrection, and Pfade.
