Patent number: 8428189Abstract: 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.Type: GrantFiled: February 17, 2010Date of Patent: April 23, 2013Assignee: NTT DoCoMo, Inc.Inventors: Hidetoshi Suzuki, Takashi Okada, Shinsuke Ogawa, Shinya Oka

Patent number: 8175060Abstract: 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.Type: GrantFiled: March 26, 2008Date of Patent: May 8, 2012Assignee: NTT DoCoMo, Inc.Inventors: Hidetoshi Suzuki, Takashi Okada, Shinsuke Ogawa, Masayuki Furusawa

Patent number: 8160521Abstract: Signals are received with a wider power range even through the use of existing AGCs than by conventional mobile communication terminals. In an AGC on one antenna side, in order to enable reception of a signal at a higher level, a target TA of a dynamic range DA of this AGC is changed to a value 5 dB higher than a value defined as a standard TS. On the other hand, in an AGC on another antenna side, in order to enable reception of a signal at a lower level, a target TB of a dynamic range DB of this AGC is changed to a value 5 dB lower than the value defined as the standard TS.Type: GrantFiled: January 17, 2006Date of Patent: April 17, 2012Assignee: NTT DoCoMo, Inc.Inventors: Yousuke Iizuka, Shinsuke Ogawa, Masahiro Sakai

A CQI correcting section corrects the CQI value that has been calculated by the CQI converter, in accordance with the block error rate. A CQI transmitter transmits the CQI value that has been corrected by the CQI correcting section, to the base transceiver station.Type: GrantFiled: April 20, 2009Date of Patent: October 11, 2011Assignee: NTT DoCoMo, Inc.Inventors: Yousuke Iizuka, Shinsuke Ogawa, Yukihiko Okumura

Mobile communication terminal and associated methodology for reception during diversity interruption
Patent number: 7853231Abstract: When the diversity reception is cut, communications with the base station are continued. When it is judged by the judgment section of the mobile communication terminal that a predetermined disconnection requirement for disconnecting diversity reception is satisfied, the gain control section of the digital baseband circuitry 20 reduces the gain of the AGC14B contained in the RF receiver circuitry 10B constituting the disconnection target by a fixed value at fixed times. Diversity reception is cut after the level of the signal output by the AGC14B has reached zero.Type: GrantFiled: January 17, 2006Date of Patent: December 14, 2010Assignee: NTT DoCoMo, Inc.Inventors: Yousuke Iizuka, Shinsuke Ogawa, Masahiro Sakai -
