摘要： A communication terminal device and a reception environment reporting method produce a more excellent throughput, by making a report of a reception environment with higher accuracy. An SIR measuring section measures an SIR from a reception signal that has been received from a base transceiver station. A CQI converter converts the SIR that has been measured by the SIR measuring section into a CQI value. A BLER calculating section calculates a block error rate of the reception signal. 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.

摘要： The packet reception section of the cellular phone receives a packet transmitted from the base station and the transmission error detection section detects a transmission error of the received packet. When the transmission error is detected, the retransmission request transmission section transmits a retransmission request to request the retransmission of the packet in which the transmission error is detected, to the base station, and the sample timing control section shifts the sample timing of the A/D converter by a half clock.

摘要： A transmission power control device is provided that includes: a transmission loss calculator that calculates a transmission loss in the electric wave transmission path between a mobile station and each base station; and a transmission power control information determiner that determines which transmission power control information is to be used in a transmission power control operation at the mobile station, based on transmission power control information transmitted from each base station to the mobile station and the transmission loss in the transmission path between the mobile station and each base station calculated by the transmission loss calculator. This transmission power control device may further include an autonomous controller that increases transmission power from a current value in accordance with predetermined characteristics, regardless of transmission power control information from another communication device, when reception signal quality has become lower than a predetermined quality level. With this structure, after synchronization with a signal from the base station is established at the mobile station, the transmission power is controlled to increase from the initial value in accordance with the predetermined characteristics, regardless of the transmission power control information transmitted from the base station.

摘要： 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.

摘要： 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.

摘要： An increase in the power consumption and deterioration of the reception characteristic which can arise as a result of installing a multi-path interference removing apparatus are suppressed. The multi-path interference removing apparatus is operated only in the following cases: a case where a mobile communication terminal is in a communication active state, a case where communication takes place via a base station to which the adaptive modulation and coding technology is applied, a case where the number of reception paths of the mobile communication terminal is two or more paths, a case where the speed of motion of the mobile communication terminal is 60 km/h or less, and a case where the Signal to Interference power Ratio is 8 dB or more.
