    摘要: Respective threshold value judging units 108-1 through 108-n compare the likelihoods calculated by the corresponding likelihood calculators 106-1 through 106-n with threshold values stored in a threshold value buffer 109 in terms of size, and output signals, which show the corresponding likelihood in only a case where the likelihood is the threshold value or more, through a likelihood transmission bus 110. The rank decision unit 112 ranks the symbols for which the likelihood is an appointed threshold value or more, on the basis of the likelihoods stored in the likelihood buffer 111, whereby it is possible to relieve the traffic of a bus line and to suppress the amount of processing in a ranking process with respect to all non-demodulated symbols.

    摘要: An interference cancellation apparatus and method may remove interference from a directional array combined signal that is received by an array antenna and array combined on a directivity-by-directivity basis. The apparatus and method input a plurality of array combined signals subjected to array combining on a directivity-by-directivity basis to select an array-combined signal corresponding to a path. A correlation value is detected between the selected array combined signal and a spread code. Detected correlation values are combined to generate a combined value, and the combined value is used to generate a temporarily determined value. The temporarily determined value is re-spread to generate a re-spread signal, and re-spread signals are sorted for every directivity, on a per path basis. The re-spread signals sorted for every directivity are then added to generate a replica signal.

    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: 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 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 radio base station apparatus may include two diversity antennas spaced apart by a distance that allows space diversity, with each diversity antenna functioning as an adaptive array antenna. Each diversity antenna has a corresponding transmitter that includes a calculator that calculates a transmission weight from one of (i) a reception weight determined based on an uplink signal and (ii) direction of arrival information. Each transmitter also has a multiplier that multiplies only a transmission signal for a channel to a specific user by the transmission weight. Also, each transmitter has a transmit power controller that controls the transmit power of the transmission signal, multiplied by the transmission weight, in accordance with a transmit power control signal.

    摘要: A determination section 301 determines whether or not a DSCH has been assigned to the communication terminal apparatus in question, and outputs a signal indicating the result of that determination to a transmission controller 102, and the transmission controller 102 changes as appropriate the degree of frequency of transmission of a signal containing shared channel information according to the result of determination by the determination section 301. That is to say, the transmission controller 102 outputs a signal containing shared channel information to a modulator 103 with a high degree of frequency when the DSCH has been assigned to that terminal, and outputs a signal containing shared channel information to the modulator 103 with a low degree of frequency when the DSCH has not been assigned to that terminal.
