Abstract:
1. A method for controlling transmission power levels in a spread spectrum time division duplex communication system having frames with time slots for communication, the method comprising: receiving at a first communication station communications from a second communication station and transmitting from the first station power commands based on in part a reception quality of the received communications; transmitting from the first communication station a first communication having a transmission power level in a first time slot; receiving at the second communication station the first communication and the power commands; measuring a power level of the first communication as received; determining a pathloss estimate based on in part the measured received first communication power level and the first communication transmission power level; and setting a transmission power level for a second communication in a second time slot from the second station to the first station based on in part the pathloss estimate weighted by a quality factor and the power commands.
