1. A method for adaptively controlling reverse link transmission power levels within a wireless communication system, comprising:

  • determining a mobility profile of a remote station within a communicating range of a base station, wherein the remote station transmits a plurality of signals to the base station at various transmission power levels by using an open loop power control scheme and a closed loop power control scheme, wherein said determining a mobility profile is based on using an average transmission power level associated with a frame of the plurality of signals to determine a level crossing value and an excursion time and using the level crossing value and the excursion time to determine a velocity classification for the remote station; and

    preventing the closed loop power control scheme if the mobility profile is unfavorable depending on the determined velocity classification for the remote station.
