1. 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 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 a first factor and a long term path loss estimate weighted by a second factor, said first and second factors being a function of a time separation of the first and second time slots; and

    means for transmitting the second communication in the second time slot at the set transmission power level.
