CDMA / TDD system wireless communication system and CDMA / TDD system mobile station and CDMA / TDD system base station and CDMA / TDD system wireless communication method

摘要

PURPOSE:To perform the transmission power control with high accuracy in a moving machine. CONSTITUTION:In addition to the constitution of a conventional CDMA/TDD mode radio communication system, a base station 100 is provided with a means 15 generating a pilot signal which is constant in a transmission power level and is known in each moving machine 200 to each moving machine 200 and a means 16 transmitting the pilot signal to the moving machine via a transmission line 5. Each moving machine 200 is provided with a means 19 measuring the reception power of the received pilot signal and a means 8 controlling the transmission power of the power amplifier circuit 10 based on the reception power of the measured pilot signal.
