A wireless telecommunications system includes at least one base station, at least one mobile station, and power control circuitry implemented in the base station and the mobile station. N/X power control indications sent from the mobile station to the base station are used to provide closed loop power control to N subchannels, where N is a total number of subchannels in use between the base station and the mobile station, and where X is a positive integer having a value within a range greater than or equal to one and less than N such that N/X, in one case, is an integer number. In one embodiment each of the N subchannels is transmitted through a separate one of N adjustable gain stages, and N/X power control indications generated at the mobile station are employed to vary the gain of the N adjustable gain stages. In another embodiment a plurality of adjustable gain stages associated with a plurality of subchannels are controlled using a same gain control signal. In the presently preferred, but not limiting embodiment, the system is a wideband, multi-carrier spread spectrum system, and the N subchannels can be overlaid on up to N other carriers.
