摘要： A communication device and a communication method capable of implementing high-speed and high-quality communication processing such as handover. 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. Further, a frequency measurement unit measures reception strength of reception signals in the expanded frequency range, and detects a frequency of, among the measured signals, a signal with a reception strength higher than a predetermined reception strength, and the communication unit executes connection processing by using the signal of this frequency.

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.
