A wireless telecommunications mobile station, which is bi-directionally coupled to a base station through a communication channel, includes a device for receiving signals over the communication channel from the base station, power control circuitry for selectively deriving power control commands, and a device for transmitting the selectively derived power control commands to the base station. The power control circuitry of the mobile station provides, in cooperation with power control circuitry of the base station, closed loop power control to the communication channel. The power control circuitry includes circuitry for selectively deriving power control commands based on one of first power control commands or second power control commands in response to a determined mobility of the mobile station. The determined mobility can be indicative of a Doppler shift of carrier transmitted from the base station, or a velocity derived from the Doppler shift.

1. A wireless telecommunications base station comprising a transceiver for being bidirectionally coupled to at least one mobile station through a radio communication channel, the base station further comprising:means for receiving power control signals over the radio communication channel from the mobile station; and power circuitry for a in cooperation with the mobile station, closed loop power control to the radio communication channel, wherein the power control circuitry comprises circuitry for determining a mobility of the mobile station and for selectively deriving power control commands based on one of first power control commands or second power control commands in response to the determined mobility of the mobile station, said second power control commands including open loop power control commands; means for determining a Doppler condition of the mobile station; and wherein said first power control commands are derived when said mobile station is in a low Doppler condition, and wherein said second power control commands are derived when said mobile station is in a high Doppler condition.
