Abstract

A wireless communication apparatus in a wireless communication system transmits power-control information on a power-control channel, separate from the traffic channels of the wireless communication system. In a code division multiple access system, the power-control channel has a separate spreading code. The power-control channel provides a steady flow of power-control information, even when traffic channels are used only intermittently.
