摘要： Received signal provided via plural antennas 101 are memorized in memory 102. First weight controller 103 calculates the first weights by which the received signals are weighted, and second weight controller 104 calculates the second weights using the received signals. Multipliers 107 and 108 multiply the memorized received signals by the first weights, while multiply the memorized received signals by the second weights when a channel quality of radio signals deteriorates due to a change of the radio signal's direction of arrival Adder 109 synthesizes the multiplication results. Propagation path distortion compensator 110 estimates a deterioration of the channel quality using synthesis result to compensate. Detector 111 detects the compensation result that is used as a parameter to calculate the first and second weights, which allows the apparatus to receive radio signals without deteriorating reception qualities when the channel quality deteriorates rapidly due to the change of the radio signal's direction of arrival.

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： 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： 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.

摘要： A transmission rate determining method that enables assignment of transmission rate (modulation scheme and coding rate) to be optimized with high accuracy in the AMC technique. In the method, in a base station, Doppler frequency detector 117 detects the Doppler frequency (moving speed) of each mobile station. MCS assignment section 125 corrects a relational expression of MCS (coding rate and modulation scheme) and CIR based on the Doppler frequency (moving speed) obtained in Doppler frequency detector 117, for example, corrects a threshold in CIR, and determines MCS optimal for CIR report value. Results of assignment in MCS assignment section 125 are output to coding section 101 and modulation section 103.

摘要： A base station transmits downlink signals to mobile terminals of users A to C with respective transmission power corresponding to downlink quality. A downlink quality estimating section (106) uses the transmission power from a transmission power control section to compare transmission power between the users, and estimates that a terminal with low transmission power has high downlink quality. The priorities are determined so that the priority is increased as the transmission power is lower. Thus determined priority information is output to a scheduling section (107). The scheduling section (107) performs scheduling based on the priority information. The section (107) assigns DSCH to terminals in ascending order of transmission power. User A is first assigned DSCH, user B is second assigned DSCH, and user C is third assigned DSCH. It is thus possible to perform scheduling and MCS selection of DSCH with the need of information from a terminal eliminated.

摘要： Gain control is performed on an input signal to an orthogonal modulator used in a radio transmitting apparatus in such a manner that the level of the input signal falls within the proper operation range of the orthogonal modulator. At the time of amplifying and outputting the output of the orthogonal modulator, gain control is executed with the reciprocal of a control gain for the input signal to the orthogonal modulator. Accordingly, the input to the orthogonal modulator of an adaptive array antenna can be compensated within the proper range to ensure the proper operation of the orthogonal modulator.
