Abstract
A method and apparatus for controlling transmission power levels in a mobile communication system. The method 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.

Claim
1. A method for controlling transmission power levels, comprising:
determining a velocity of a first station;
using the velocity of the first station at a second station to determine an anticipatory power adjustment; and
making the anticipatory power adjustment prior to receiving a power adjustment request signal from the first station.', 'determining a velocity of a first station;', 'using the velocity of the first station at a second station to determine an anticipatory power adjustment; and', 'making the anticipatory power adjustment prior to receiving a power adjustment request signal from the first station.
2. The method of claim 1, wherein said determining the velocity of the first station is performed by a motion sensor at the second station.
3. The method of claim 1, wherein said determining is based on determining the velocity of the first station by a sensor at the second station that detects a shift in an incoming traffic signal from the first station.
4. The method of claim 1, wherein said determining is based on determining the velocity of the first station by a sensor at the second station that detects selected changes in an incoming traffic signal received from the first station.
5. The method of claim 3, wherein said determining the velocity of the first station is based on determining changes in relative velocity of the first and second stations by measuring a Doppler shift in a pilot signal.
6. An apparatus for controlling transmission power levels, comprising:
means for determining a velocity of a first station;
means for using the velocity of the first station at a second station to determine an anticipatory power adjustment; and
means for making the anticipatory power adjustment prior to receiving a power adjustment request signal from the first station.', 'means for determining a velocity of a first station;', 'means for using the velocity of the first station at a second station to determine an anticipatory power adjustment; and', 'means for making the anticipatory power adjustment prior to receiving a power adjustment request signal from the first station.
7. The apparatus of claim 6, wherein the means for determining the velocity of the first station is a motion sensing means.
8. The apparatus of claim 6, wherein the means for determining the velocity determines the velocity by determining any shift in an incoming traffic signal from the first station.
9. The apparatus of claim 6, wherein the means for determining the velocity determines the velocity by determining selected changes in the incoming traffic signal received from the first station
10. The apparatus of claim 8, wherein the means for determining the velocity determines velocity by measuring the Doppler shift in a pilot signal
11. An apparatus for controlling transmission power levels, comprising:
a control processor for determining an anticipatory power adjustment of a transmission power based upon a velocity of a mobile station and to generate a signal that is indicative of the anticipatory power adjustment; and
a transmitter for receiving the signal that is indicative of the anticipatory power adjustment and to modify the transmission power.', 'a control processor for determining an anticipatory power adjustment of a transmission power based upon a velocity of a mobile station and to generate a signal that is indicative of the anticipatory power adjustment; and', 'a transmitter for receiving the signal that is indicative of the anticipatory power adjustment and to modify the transmission power.']
