Abstract (en)

[origin: WO9966744A1] A power control device for a mobile station in a CDMA communication system including a base station which transmits a traffic signal via one of at least two antennas and transmits a common channel signal via another antenna. The device comprises a receiver for receiving the transmitted traffic and common channel signals via one antenna; an interference power measurer for measuring power of an interference signal output from the receiver; a common channel power measurer for measuring power of the common channel signal output from the receiver; a traffic channel power measurer for measuring power of the traffic signal output from the receiver; a power control bit generator fo generating a power control bit for a traffic-OFF channel which has transmitted the common channel signal by operating the power of the pilot and interference signals; and a multiplexer for multiplexing the power control bit to a reverse link channel.
