A spread spectrum time division duplex user equipment uses frames having time slots for communication. The user equipment receives power commands and a first communication having a transmission power level in a first time slot. A power level of the first communication is measured as received. A pathloss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. A transmission power level for the second communication in a second time slot form the user equipment is set based on in part the pathloss estimate weighted by a quality factor adjusted by the power command. The quality factor decreases as a number of time slots between the first and second time slots increases.
A spread spectrum time division duplex user equipment, the user equipment using frames with time slots for communication, receiving power commands and receiving a first communication having a transmission power level in a first time slot, measuring a power level of the first communication as received and determining a pathloss estimate based on in part the measured received first communication power level and the first communication transmission power level, the user equipment comprising:
