1. A method of adjusting a signal power in a variable data rate mode of a mobile communication system, comprising:
- allocating a reference pilot signal level to each of a plurality of data rates supported by the system;
determining a data rate based on an external control information;
transmitting a data rate information corresponding to the determined data rate;
adjusting a power control threshold that is compared with the reference pilot signal level to generate a value of a power control bit for controlling the reference pilot signal level; and
adjusting the reference pilot power signal level based on the determined data rate.

Abstract
The present invention relates to a mobile communication system, and more particularly, to a method of adjusting a signal power in a variable data rate mode. Accordingly, the present invention includes steps of allocating a reference pilot signal level to each of a plurality of data rates supported by the system and adjusting the reference pilot signal level for a changed data rate based on an external control information and adjusting a power control threshold for secondly adjusting the reference pilot signal level corresponding to the reference pilot signal level.
