摘要： A transfer rate decision method capable of optimizing transfer rate (modulation method and coding rate) allocation with a high accuracy in the AMC method. In this method, a base station detects a Doppler frequency (moving speed) of each mobile station by using a Doppler frequency detector (117). According to the Doppler frequency (moving speed) obtained by the Doppler frequency detector (117), an MCS allocation unit (125) corrects a relationship expression between the MCS (coding rate and modulation method) and a CIR. For example, a threshold value of the CIR is corrected and an optimal MCS for the CIR report value is decided. The allocation result (coding rate and modulation method) of the MCS allocation unit (125) is output to a coding unit (101) and a modulation unit (103).

摘要： Based on the determination of a transmission destination determination section 106, a data selector 151 selects only transmit data for the corresponding communication terminal apparatus. An adaptive modulation section 153 modulates the output signal from the data selector 151 using the modulation method indicated by a modulation method determination section 152. A spreading section 154 spreads the output signal from the adaptive modulation section 153 and outputs the resulting signal to a code multiplexer 158. A dedicated pilot signal generator 155 generates a dedicated pilot signal. A modulation section 156 modulates the dedicated pilot signal. A spreading section 157 spreads the output signal from the modulation section 156 and outputs the resulting signal to the code multiplexer 158. The code multiplexer 158 performs code multiplexing of the output signal from the adaptive spreading section 154 and the output signal from the spreading section 157 and outputs the resulting signal to a time multiplexer 162. By this means it is possible to maintain data-part reception quality when performing high-speed downlink packet transmission even when phase changes are sudden.

摘要： 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.

摘要： The radio reception section 1102 receives a received signal whose band has been restricted using a filter. The delay profile creation section 1104 creates continuous delay profiles for every midamble shift. The distortion component creation section 1106 creates start path distortion components by multiplying the power value of the start sample of each midamble shift by a coefficient of the filter. The removing section 1107 removes the start path distortion components of the following midamble shift from predetermined samples behind the delay profile of each midamble shift. The path selection section 1108 selects samples whose power value is equal to or greater than a threshold as paths from the delay profile with the start path distortion components removed as paths.

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： Priority order storage section 113 stores the order of priority for an uplink and the reverse order of priority for a downlink. Channel allocation section 114 performs channel allocation for a downlink in the order of priority of the downlink stored in priority order storage section 113, based on the CIR of the downlink. In addition, channel allocation section 114 performs channel allocation for an uplink in the order of priority of the uplink stored in priority order storage section 113, based on the CIR of the uplink. It is thereby possible to perform reuse partitioning in asymmetrical data communications.
