Abstract
A method for controlling power of an uplink physical channel includes: computing a relative gain factor in a compressed mode; correcting the relative gain factor to obtain a corrected relative gain factor; generating a gain factor in the compressed mode according to the corrected relative gain factor; controlling power of the uplink physical channel according to the gain factor in the compressed mode generated. In embodiments of the present invention, after being computed, the relative gain factor in the compressed mode is corrected, then the gain factor in the compressed mode is generated according to the corrected relative gain factor. Thus, an accurate gain factor may be acquired for controlling the power of the uplink physical channel.
