Power control device and method for reverse link common channel in mobile communication system |
摘要 |
A method for controlling the transmission power of the reverse common channel for a mobile station in a CDMA communication system. In the method, the mobile station transmits a preamble signal at predetermined periods with increasing transmission power. Upon receipt of an acknowledge signal from a base station, the mobile station accesses the reverse common channel. In order to avoid multiple mobile stations from simultaneously generating increasingly powerful and interfering transmissions, the method generates two transmission power control signals: one based on the measured strength of a signal received from the base station and the other based on an accumulated value of power control commands transmitted by the base station. These two signals are accumulated and used to control the preamble signal.
