摘要： An antenna 20 receives signals orthogonal to each other transmitted from different antennas of a base station, and a despreader 202 and a spreader 203 despread the respective received signals using the same spreading code used in the base station, a demodulator 204 and a demodulator 205 demodulate the despread signals, a reception power measuring section 207 and a reception power measuring section 208 measure reception power from the demodulation results, a reception power combiner 209 combines measured reception power, and a transmission power controller 212 controls transmission power based on combined reception power. This makes it possible to perform open loop transmission power control at high speed and with high accuracy even when a fading variation is small.

摘要： Spreading sections of the base station spread the respective distributed data using mutually orthogonal spreading codes and are transmitted from antennas. Despreading sections of the mobile station despread the received signals using the same spreading codes as those used at the base station. Demodulation sections demodulate the despread signals. Received signal power measuring sections measure their received signal powers from the demodulation result. A received signal power combination section combines the measured received signal powers and a transmit power control section controls transmission power based on the combined received signal power. When carrying out diversity reception through a plurality of antennas at the base station, transmit power control errors are suppressed to a small level at the mobile station.

摘要： In a receiving side apparatus 150, reception quality of receive data is measured by a reception quality measurement section 157, receive data errors are detected by an error detection section 156, and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section 158. In a transmitting side apparatus 100, when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus 150 is detected from a reception quality signal by a scheduling section 110, and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.

摘要： A mobile station apparatus in a CDMA/TDD mobile communication system employs a communication frame including a plurality of time slots. The time slots include a plurality of forward link time slots, disposed at regular intervals in the communication frame and assigned a common control channel. The time slots further include time slots other than the plurality of forward link time slots, divided into reverse link time slots and forward link time slots according to an amount of information on a forward link and on a reverse link. The mobile station apparatus includes a receiver that receives the communication frame including the plurality of time slots. A measurer measures individual reception qualities of the plurality of forward link time slots in the received communication frame including the forward link time slots assigned the common control channel. A weighter assigns a weight to each measured reception quality of the plurality of forward time slots. A transmission power controller performs transmission power control for reverse link time slots according to individual reception qualities of weighted forward link time slots.

摘要： First and second phase control amount tables output to first and second vector multiply circuits phase control signals Sc1 and Sc2 representative of corresponding phase shift amounts with gains represented by input gain control signals Sg1 and Sg2 as arguments. The first and second vector multiply circuits shift the phases of in-phase components S13 and S23 and quadrature components S14 and S24 of an antenna 2 in opposite directions in accordance with the phase control signals Sc1 and Sc2. Consequently, the amount of phase shift caused by receiving amplifiers is corrected so that the phase difference at antenna terminals between the input signals to the antennas is maintained.
