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： 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： A disclosed communication terminal includes a determination unit analyzing a received downlink control signal and determining an allowable maximum uplink transmission power level, a measurement unit performing different frequency measurement in a transmission gap period, a threshold determination unit determining whether the allowable maximum level is higher than or equal to a threshold within a predefined period before the start and/or after the end of the transmission gap period, a transmission power control unit setting an uplink transmission power level, and a transmission unit transmitting an uplink signal at the determined power level. If the allowable maximum level is higher than or equal to the threshold, the transmission power control unit sets the uplink transmission power level to or below a predefined level lower than the allowable maximum level within the predefined period before the start and/or after the end of the transmission gap period.

摘要： Properties of a mobile communication terminal car be improved by eliminating interference according to environments of various reception paths. The mobile communication terminal generates a delay profile by a common pilot chapel sent from a base station and measures received electric power and delay amount of the reception path. Next, based on the delay profile, the delay amount of a reception path P4 farthest from a reference path P1 is set as a maximum delay amount D. However the farthest reception path P4 is excluded from the subjects of interference elimination when the electric power of which differs by a amount not less than 10 dB with respect to the electric power of the reference path P1, and the delay amount of a reception path P3 next farthest from the reference path P1 is set as the maximum delay amount D. After that, a chapel matrix s generated based on the number of samples and the maximum delay amount D. Then interference is eliminated by multiplying a channel actually carrying data information by a weighting matrix generated based on the channel matrix.
