FORWARD LINK CLOSED LOOP POWER CONTROL BASED ON MOBILE STATION MOBILITY

WIPO Patent Application WO2000033479

A9

A wireless telecommunications mobile station (10), which is bidirectionally coupled to a base station (30) through a communication channel (29), includes a device (64) for receiving signals over the communication channel from the base station, power control circuitry (18a) for selectively deriving power control commands, and a device (74) 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 (70, 72) 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.
