First Claim
1. An apparatus for controlling transmission power from a central communications station comprising:
- receiver means for receiving a signal from a remote station;
transmitter means for adjusting a transmission power in accordance with said received signal wherein following a transmission power increase, reducing said transmission power at a first nonzero predetermined rate for a predetermined time period and reducing said transmission power at a second nonzero predetermined rate which is unequal to said first predetermined rate following said predetermined time period.

Abstract
A method and apparatus for controlling transmission power in a mobile communication system, which provides for a closed-loop power control method. A mobile station provides information on the quality of the signal received from the base station, and the base station responds by adjusting the power allocated to that user in a shared base station signal. The transmission power is adjusted initially by a large increment and then ramped down at an increasingly decreasing rate. The mobile station also provides information to the base station as to its relative velocity and the base station adjusts its transmission power in accordance with this velocity information.
