Title: Cdma mobile communication system
Inventor: WATANABE MASATOSHI
IPC: H04J13/18
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To avoid spreading code shortage of an outgoing line while performing transmission power control of an incoming line even at the time of asynchronous communication only by the incoming line in a CDMA cellular system. SOLUTION: At the time of asynchronous communication only by an incoming line, a frame constitution part 103 transmits only a pilot signal and a transmission power control bit as a signal constituted into a slot unit. A transmission power control method is performed similarly a normal communication. In this case, as a signal transmitted in an outgoing line is only the pilot signal and the transmission power control bit, a carrier rate is lowered, the transmission power is lowered by a transmission signal amplitude control part 106 and can be transmitted. Moreover, in that case, a spreading code used in a diffuser 105 is transmitted as a hierarchy orthogonal system of long code length.
