Title:
無線通信端末装置及び無線通信方法
Document Type and Number:
Japanese Patent JP4769334
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication terminal device, a radio communication base station device, and a radio communication method capable of automatically changing over a communication mode.SOLUTION: A carrier monitoring unit 106 monitors the carrier (frequency) of a signal which is output from a radio reception unit 105. A setting timing adjustment unit 107 outputs a timing signal to an F1/F2 changeover unit 108 to thereby change over F1 and F2 at prescribed timing. The F1/F2 changeover unit 108 outputs a carrier changeover signal to the radio reception unit 105, based on a carrier detection result which is output from the carrier monitoring unit 106 and the timing signal which is output from the setting timing adjustment unit 107. When the carrier detection result indicating the presence of a carrier is output from the carrier monitoring unit 106, a demodulation unit 109 performs demodulation processing in the signal which is output from the radio reception unit 105, and outputs demodulation data to a decoding unit 110.
