ABSTRACT:
A TDD (Time Division Duplexing) CDMA (Code Division Multiple Access) communication system performs power control in a closed-loop power control mode in a data transmission period, but performs the power control using a modified open loop power control method and an open loop power control method as well as the closed-loop power control method in a transmission pause period, thereby to properly set initial transmission power after the end of the transmission pause period.
