Patent ID: 7869410

Claim:
A method of controlling forward link traffic channel transmission power, P transmit , to a user terminal by an entity in a wireless communications system having a plurality of beams, comprising the steps of: (a) receiving from the user terminal an in-use formatted message signal to noise ratio (SNR); (b) determining a baseline power level, P baseline , from the received formatted message SNR, wherein the determining step comprises calculating a power level offset; (c) identifying a user terminal interference susceptibility comprising identifying at least one other user terminal within the plurality of beams and a data rate of the at least one other user terminal; (d) determining a power margin, P margin , from the identified interference susceptibility; (e) identifying a packet error rate (PER) associated with the user terminal; (f) determining a power level correction factor, P correction , based on the PER; and (g) setting P transmit based on P baseline , P margin , and P correction .
