Abstract
A method of forward link power control in a CDMA mobile communication system is adapted for diversity transmission. First and second diversity signals are transmitted from a base station to a mobile terminal. The mobile terminal derives first and second channel quality estimates associated with the first and second diversity signals respectively. The mobile terminal uses the channel quality estimates to derive first and second power control codes which it transmits to said base station. The base station adjusts the transmit power of first and second antennas associated with the base station based on the first and second power control codes, respectively.
