An enhanced mechanism for the reverse link power control in a wireless communication system, especially for high speed data applications and fixed wireless communication applications, dynamically adjusts the power control step size of the reverse link power control. The power control step size is dynamically adjusted based on various factors including types of service, number of reverse supplemental code channels, total received power at the base station, estimated diversity gain and required mobility, among others. The system which includes stationary infrastructure, can query a subscriber unit's capability in the support of a pre-defined set of power control step sizes before assigning it to the subscriber unit. Furthermore, the subscriber unit may decide its optimized power control step size based on certain feedbacks from the system. In a specific embodiment, enhancement to the ANSI EIA/TIA-95 system is provided such that it supports a variable subscriber unit power control step size and associated signaling in accord with this invention.

[ We claim:] [1.] A wireless communication system serving at least one subscriber unit operating within a respective service, the wireless communication system comprising:a base station that provides wireless coverage within the service area, the base station establishing a forward link and a reverse link with the subscriber unit, communications transmitted to the subscriber unit on the forward link and communications received from the subscriber unit on the reverse link;the base station, based upon system conditions and reverse link power control step sizes supported by the subscriber unit, selecting a reverse link power control step size for the subscriber unit;the base station directing the subscriber unit to make adjustments to the power level of reverse link transmissions by a selected power control step size; andbased upon the power level of reverse link transmissions from the subscriber unit received by the base station, the base station periodically directing the subscriber unit to increment or decrement the power level of reverse link transmissions by the selected power control step size in an attempt to cause the reverse link transmissions to arrive at the base station at a desired power level.
