    摘要: It is possible to prevent lowering of a throughput of a radio communication system even when propagation path environments of an uplink line and downlink line are asymmetric. A maximum proper value calculation unit (115) calculates a maximum proper value from a channel matrix. A maximum proper value comparison unit (116) compares the maximum proper value with a maximum proper value of the downlink line reported separately from a base station. According to the comparison result obtained by the maximum proper value comparison unit (116), a proper mode initiative instruction unit (117) decides to pass the proper mode initiative to a communication partner or to the local device. When the initiative is to be passed to the local device, this fact is reported to a proper bam correction unit (118). When the proper beam correction unit (118) gets the proper mode initiative, the proper beam correction unit (118) corrects the correlation matrix by using the proper values of both of the downlink line and the uplink line and instructs a directivity forming unit (103) to form a proper beam according to the correlation matrix after the correction.

    摘要: A base station apparatus may include a plurality of antenna element groups that each have a plurality of antenna elements arranged in a vertical direction. A reception weight combining section generates a combined signal for each antenna element group by multiplying a signal received by each antenna element of the group with a weight and combining the weighted signals of the antenna element group. A selection section measures reception power of the combined signal for each antenna element group and selects an antenna element group based on the measured reception powers. A transmission weight combining section multiplies a transmit signal with a weight applied by the reception weight combining section to a signal received by an antenna element of the selected antenna element group, and a diversity transmission section transmits the transmit signal from the selected antenna element group.

    摘要: A base station apparatus and communication terminal apparatus capable of estimating interference with other cells on an uplink and realizing optimum assignment. At a base station (100), a scheduling and transmission parameter determining section (113) receives soft handover information from a higher layer and does not perform individual assignment processing for a mobile station in the process of soft handover. In this way, the mobile station can perform continuous transmission at a constant transmission rate (e.g., coding rate, modulation scheme, spreading factor, transmit power, etc.).

    摘要: An envelope calculation section (113) calculates the amplitude of a transmission signal after the multiplexing thereof. When the calculated amplitude is beyond a permissible amplitude value, a correction coefficient calculation section (114) calculates a correction coefficient that is the difference between amplitude values before and after a correction. Multiplication sections (115) and (116) calculate a correction value by multiplying a filter coefficient by a correction coefficient. Subtraction sections (119) and (120) subtract the correction value from the transmission signal after a filtering operation. Thereby, the transmission amplitude at the time of a peak can be suppressed without increasing the number of filter operation circuits.

    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.
