Abstract
Provided with a method of performing power control in a CDMA mobile communication system, characterized by including the steps of: repeatedly updating information concerning the change of a channel state between a mobile station and a base station at regular intervals; varying a channel gain up/down time and/or a channel gain up/down delta adaptively based on the updated information; and adjusting the channel gain between the mobile station and the base station.

A method of performing power control in a mobile communication system, comprising:
- receiving a plurality of frames from a mobile terminal at prescribed regular intervals;
- receiving error rate information concerning the plurality of received frames from the mobile terminal;
- repeatedly updating information concerning a change of a channel state between a mobile station and a base station at the prescribed regular intervals;
- varying at least one of a channel gain up/down time and a channel gain up/down delta adaptively based on the error rate and the channel state;
- and
- adjusting the channel gain between the mobile station and the base station in at least one of an upward and downward adjustment.
A method of performing power control in a mobile communication system, comprising:
- receiving frames from a mobile terminal at prescribed regular intervals after a call between the mobile terminal and a base station has been established;
- extracting an erasure indicator bit from the received frames;
- increasing a modular frame counter by “1”;
- determining current and previous channel states for each of the prescribed regular intervals;
- adaptively varying at least one of a channel gain up/down time and a channel gain up/down delta based on a current forward error rate and the previous channel state for each of the prescribed regular intervals;
- and
- adjusting the channel gain between the mobile station and the base station in one of an upward or downward adjustment.
