Automatic power control for a CDMA communications system

摘要

A method for controlling transmission power levels of a code division multiple access, CDMA, subscriber unit, the method comprising receiving by the subscriber unit a power control bit on a downlink control channel, the power control bit indicating either an increase or decrease in transmission power level; transmitting a plurality of channels by the subscriber unit, the plurality of channels including a traffic channel and a reverse control channel; in response to the received power control bit, adjusting a transmission power level of both the traffic channel and the reverse control channel, wherein the transmission power level of the traffic channel and the reverse control channel are different; and transmitting the traffic channel and the reverse control channel at their respective adjusted transmit power levels.
