A mobile communication terminal is configured such that, in cases where it is judged by a power measurement unit that a reception signal received by a communication unit is equal to or less than a predetermined value, a frequency conversion unit performs computation by expanding a frequency range for performing time/frequency conversion with respect to the received reception signal.

摘要： A determiner determines whether or not a mobile communication terminal is in a standby mode. A fast Fourier transform calculator demodulates a signal which is received at the mobile communication terminal. A controller causes the fast Fourier transform calculator to vary at least one of a frequency range for fast Fourier transform or a number of frequency samples used by the fast Fourier transform calculator, depending on determination by the determiner. Preferably, the controller is adapted to cause the fast Fourier transform calculator to vary at least one of the frequency range for fast Fourier transform or the number of frequency samples used by the fast Fourier transform calculator based on information about frequencies used in communication from a radio base station to the mobile communication terminal and notified from the radio base station.

摘要： The transmission power is decreased in an appropriate manner, while suppressing the deterioration of the line quality to the minimum. A mobile communication terminal 1 controls the transmission power in response to a request given from a base transceiver station 2. When an average transmission power Wa that is an average value of the transmission power in a monitoring period Ta is smaller than a threshold value TH, mobile communication terminal 1 continuously controls the transmission power in response to the request given by the base transceiver station 2. When the average transmission power Wa in the monitoring period Ta is equal to or greater than the threshold value TH, the transmission power is controlled in a transmission power suppressing period Tb that follows the monitoring period Ta so that the average value of the transmission power becomes equal to or smaller than the threshold value in a control period Tc including the monitoring period Ta and the transmission power suppressing period Tb. The average value of the transmission power is thus decreased in the entire control period Tc.

摘要： A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit (214) primarily spreads a response signal by use of a ZAC sequence established by a control unit (209). A spreading unit (217) secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit (209). The control unit (209) controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit (214) and the block-wise spread code sequence to be used for the secondary spread in the spreading unit (217). The hopping pattern established in the control unit (209) is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.
