ABSTRACT:
Forward link transmission power to a user terminal in a wireless communications system having a plurality of beams is controlled by determining a baseline power level, Pbaseline, from a received active pilot channel signal-to-noise ratio (SNR); determining a power margin, Pmargin, from an identified interference susceptibility; determining a power level correction, Pcorrection, based on an identified packet error rate (PER); and setting Ptransmitbased on Pbaseline, Pmargin, and Pcorrection. For example, Ptransmitmay be set to a power level that is substantially equal to the sum of Pbaseline, Pmargin, and Pcorrection. The determination of each of Pbaseline, Pmargin, and Pcorrectionmay be performed in independently running control loops or processes.
