Patent ID: 7917165

Claim:
A power control method for a base station, comprising: A. adjusting, by the base station, a transmit power of a code-channel occupied by a terminal according to a power control command from the terminal; B. determining a permitted minimum code-channel power according to an adjusted transmit power of the code-channel occupied by the terminal, comprising obtaining a maximum code-channel power in all the code-channels occupying the same carrier frequency and the same time slot, and taking a difference between the maximum code-channel power and a corresponding code-channel power difference threshold as the minimum code-channel power permitted by all the code-channels in the carrier frequency and the time slot; C. correcting the transmit power of the code-channel occupied by the terminal according to the minimum code-channel power; and D. transmitting a signal to the terminal according to a corrected transmit power of the code-channel occupied by the terminal.
