Method and apparatus for controlling downlink transmission power in mobile communication system using site diversity

摘要

The present invention controls the initial downlink transmission power using an initial control signal transmitted from the mobile station and received at each base station, and the additional downlink transmission power using the additional control signal transmitted from the base station control station to the base station, A method and apparatus for controlling downlink transmission power in a mobile communication system using site diversity. Further downlink transmit power control may be transmitted at the mobile station and received at the base station control station. Initial downlink transmit power control is performed during the non-site diversity period, and additional downlink transmit power control is performed during the site diversity period. Alternatively, both initial downlink transmit power control and additional downlink transmit power control may be implemented during the site diversity period.
