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 energy of a communication station, comprising:
determining a characteristic of a propagation path between said communication station and a second communication station;
increasing said transmission energy of said communication station by a first amount in accordance with a power control step size corresponding to said characteristic of the propagation path;
decreasing said transmission energy of said communications station from the first amount at a first predetermined rate for a period of time; and
decreasing said transmission energy at a second predetermined rate after said period of time.', 'determining a characteristic of a propagation path between said communication station and a second communication station;', 'increasing said transmission energy of said communication station by a first amount in accordance with a power control step size corresponding to said characteristic of the propagation path;', 'decreasing said transmission energy of said communications station from the first amount at a first predetermined rate for a period of time; and', 'decreasing said transmission energy at a second predetermined rate after said period of time.
2. An apparatus for controlling transmission energy of a communication station, comprising:
a receiver configured to receive a characteristic of a propagation path between said communication device and a second communication station; and
a processor configured to increase the transmission energy of said communication station by a first amount in accordance with a step size corresponding to said characteristic, decrease said transmission energy of said communication station from the first amount at a first predetermined rate for a period of time, and decrease said transmission energy at a second predetermined rate after said period of time.', 'a receiver configured to receive a characteristic of a propagation path between said communication device and a second communication station; and', 'a processor configured to increase the transmission energy of said communication station by a first amount in accordance with a step size corresponding to said characteristic, decrease said transmission energy of said communication station from the first amount at a first predetermined rate for a period of time, and decrease said transmission energy at a second predetermined rate after said period of time.
3. An apparatus for controlling transmission energy of a communication station, comprising:
means for determining a characteristic of a propagation path between said communication station and a second communication station;
means for increasing said transmission energy of said communication station by a first amount in accordance with a power control step size corresponding to said characteristic of the propagation path;
means for decreasing said transmission energy of said communications station from the first amount at a first predetermined rate for a period of time; and
means for decreasing said transmission energy at a second predetermined rate after said period of time.', 'means for determining a characteristic of a propagation path between said communication station and a second communication station;', 'means for increasing said transmission energy of said communication station by a first amount in accordance with a power control step size corresponding to said characteristic of the propagation path;', 'means for decreasing said transmission energy of said communications station from the first amount at a first predetermined rate for a period of time; and', 'means for decreasing said transmission energy at a second predetermined rate after said period of time.']
