Patent ID: 7120188

Claim:
A user equipment for a spread spectrum time division duplex communication using frames with time slots for communication, comprising: means for receiving, in a first time slot, a first communication having a transmit power level and measuring a power level of said communication; means for determining a path loss estimate based in part on said measured power level and said received power level; means for determining a long term pathloss estimate; means for multiplying a first weighting factor, α, by the determined pathloss estimate, producing a weighted pathloss estimate; means for multiplying a second weighting factor, (1−α), to the determined long term pathloss estimate, producing a weighted long term pathloss estimate; means for setting a transmission power level for transmission of a second communication in a second time slot based in part on the path loss estimate weighted by the first factor and the long term path loss estimate weighted by the second factor; and means for transmitting the second communication in the second time slot at the set transmission power level.
