Abstract: A CIR measuring section 307 measures CIRs of all blocks received and a block selection section 308 makes a threshold decision based on the CIR measurement result and threshold information according to an amount of traffic in the own cell and neighboring cells. As a result of the threshold decision, blocks whose CIRs exceed the threshold are regarded as usable blocks. A CIR averaging section 309 averages the CIRs of the usable blocks and a CQI generation section 310 generates a CQI based on the CIR average value. The CQI generated and selected block numbers are reported to a base station apparatus. This allows the throughput of the own cell and neighboring cells to be improved.

Abstract: The communication terminal apparatus measures reception quality and reports the measurement result to the base station apparatus, and the base station apparatus switches the transmission rate based on the reported result of the reception quality. In this way, the transmission rate is switched starting at the point in time at which the reception quality of the communication terminal apparatus deteriorates. Furthermore, the transmission rate is switched so that the amount of interference with others is within the allowable range according to the channel condition between the communication terminal apparatus and base station apparatus.

Abstract: A parity bit generating section 110 generates parity bits of FEC for error correction from transmission data. A transmission power deciding section 111 decides transmission power at the time of retransmitting the parity bits from the number of information bits of transmission data and the number of parity bits. A transmission power controller 112 controls transmission power based on information decided by the transmission power deciding section 111 and outputs the resultant to a radio transmission section 104.

Abstract: A first scheduler 152 carries out scheduling deciding a destination apparatus based on radio line quality prediction results from a radio line quality prediction section 107. A second scheduler 153 carries out scheduling on a time slot to which a packet to be retransmitted is assigned by the first scheduler 152, based on the radio line quality prediction results from the radio line quality prediction section 107 and the scheduling results of the first scheduler 152. A transmission control section 155 controls a transmission queue 156, an error correction encoding section 158 and a modulation section 159, in accordance with the scheduling results of the first scheduler 152 when a signal is an ACK signal, and in accordance with the scheduling results of the second scheduler 153 when the signal is a NACK signal. In this way, even when a transmitted packet is correctly demodulated, other packet can be transmitted in the time slot to which a packet to be retransmitted is assigned, so that decrease in the transmission rate can be prevented.

Abstract: A mobile communication system which is capable of, when carrying out mobile communication using a shared channel, increasing in efficiency of transmission timing of the data transmission rate request value to prevent wasteful power consumption and hence reduce power consumption. The mobile station apparatus 102 of the mobile communication system measures CIR of the received signal from the base station apparatus 101 at the CIR measuring section 306, and decides the data transmission rate request value corresponding to the measured CIR value at the rate request value deciding section 307. Also, it detects an error of the received signal at the CRC section 304, and, when no error is found, calculates a difference between the average data transmission rate from the base station apparatus 101 and the data transmission request value at the rate request value transmission controlling section 308. Then, it transmits the data transmission rate request value to the base station apparatus 101 only when the obtained difference is larger than a threshold value.

Abstract: 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 abase 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.

Abstract: In a radio reception apparatus, a judgement unit judges inter-transmission users. A controller specifies the number of inter-transmission users in accordance with the judgement result. The controller calculates a power value of a received signal per one person of inter-transmission user from both of a power value of the received signal and the number of inter-transmission users. The controller estimates a power value in the case where all the members of inter-communication users come into inter-transmission users from both of the calculated power value and the number of inter-communication users.
