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.

摘要： Transmission diversity and adaptive array antenna transmission is executed with respect to a user to which a shared channel is assigned, or a pilot channel is shared a like a shared channel. By this means it is made possible to secure a large number of users without code resource shortages even where adaptive array antenna is applied to a shared channel.

摘要： If position detection is performed correctly, connection switch 161 is connected through a control signal and transmit power control circuit 162 carries out transmit power control based on reception power of a signal combining direct wave signals and delay wave signals. If position detection is not performed correctly, connection switch 161 is disconnected through a control signal and transmit power control circuit 162 performs transmit power control only based on reception power of the direct wave signals. Thus, it is possible to make reliable position detection compatible with reduction of interference in reception processing of signals of other stations.

摘要： Spreading sections 104 and 105 of the base station spread the respective distributed data using mutually orthogonal spreading codes and they are transmitted from antennas 106 and 107. Despreading sections 202 and 203 of the mobile station despread the received signals using the same spreading codes as those used at the base station, demodulation sections 204 and 205 demodulate the despread signals, received signal power measuring sections 207 and 208 measure their received signal powers from the demodulation result, received signal power measuring section 209 combines the measured received signal powers and transmit power control section 212 controls transmission power based on the combined received signal power. When carrying out diversity reception through a plurality of antennas at the base station, this suppresses transmit power control errors to a small level at the mobile station.

摘要： Error detection section 109 carries out error detection using demodulated data and outputs an error rate to SIR versus error rate estimation section 110. SIR versus error rate estimation section 110 estimates an SIR versus error rate and outputs the result of decision as to whether the correction of the target SIR value is necessary or not to target SIR correction section 111. Target SIR correction section 111 corrects the target SIR value based on the decision result. The information on the demodulation capability of a BTS is output to G parameter control section 112 and G parameter control section 112 determines an optimal gain factor. A G parameter indicating the determined gain factor is output to multiplexing section 107 of the BTS. The G parameter is output to SIR versus error rate estimation section 110. This makes it possible to perform communications with an optimal gain factor and target SIR during diversity handover between base stations with and without an interference canceller or between base stations with interference cancellers of different capabilities.

摘要： A base station receives a signal resulting from multiplexing a communication signal spread using a signal-specific spreading code and sent by mobile station apparatus and a calibration (CAL) signal spread using a signal-specific spreading code and sent for each unit frame for a predetermined time by a CAL radio signal generator in a same frequency band. An A/D conversion/despreading section and an A/D conversion/despreading section extract the communication signal and CAL signal from the received signal. A calibration processing section carries out calibration processing using the CAL signal in parallel with a communication using the communication signal. An array combining/signal processing section carries out demodulation processing on the communication signal using the calibration processing result.
