Communication terminal device, cellular radio communication system, and information communication method

摘要

The present invention relates to a communication terminal device, a cellular radio communication system, and an information communication method, and measures the reception conditions of control information at a higher degree of accuracy. The present invention can measure the reception conditions S10 from the control information SCCH at a higher degree of accuracy by receiving a transmission signal S5 of the information symbol groups composed of the control information SCCH transmitted through a predetermined frequency channel CCH, demodulating the reception signal S6 to extract noise components (S15, S20) separated from signal components by comparing the control information SCCH with reference information Sref used as a reference for comparison, and measuring the reception condition S10 of only the signal components S33 of the transmission signal S5 based on the noise components (S15, S20). <IMAGE>
