Patent ID: 7961773

Claim:
A User Equipment (UE) comprising: a receiver configured to receive a signal that includes a transmission power level parameter, over a channel; a power measurement device configured to measure a power level of the received signal; an average pathloss estimation device configured to: determine an instantaneous pathloss, L, that is a difference in value of the transmission power level parameter and the measured power level of the received signal; output an average pathloss, L o , based upon the determined L; a quality control device configured to: determine a quality of the L o ; apply a weighting factor α having a value between 0 and 1; and output a transmit power level adjustment; and a transmit power level determination device configured to determine a power level of a subsequent transmission signal from the UE based on the transmit power level adjustment, wherein the power level of the subsequent transmission is directly proportional to a sum of three factors: a first factor that is determined by multiplying the weighting factor α with the difference of L and L o ; a second factor that is L; and a third factor that is at least one other value received by the UE.
