The present invention provides a method and an apparatus for communication with at least one wireless unit over a forward and a reverse link in a wireless network. The method includes receiving a feedback indication on at least a first channel over the forward link for reception of a transmission on at least a second channel over the reverse link, and adjusting transmit power of a wireless unit associated with the network based on the feedback indication. For example, a transmitter at a wireless unit associated with a spread spectrum wireless network, such as a code division multiple access cellular network, may control transmit power of in a reverse link. Specifically, the feedback indication for reception of a traffic or control channel over the reverse link may be received on a channel that is available on the forward link for another purpose than providing power control feedback. In this way, the transmitter performs reverse link power control at the wireless unit. By performing such reverse link power control, the transmitter obviates many conventional drawbacks associated with a receiver-centric power control in a feedback-based spread spectrum wireless communications system.
