    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: The signaling amount in selecting a plurality of beams is reduced in pre-coding to thereby enhance the throughput. To select a plurality of beams when the pre-coding is applied, when notification of a beam number is provided in a feedback signal from a user equipment 102 as a reception station to a radio base station 101 as a transmission station, a superior beam number having a high quality rank with small time variation is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the time period. For example, to select three beams from six beams, first, notification of the superior two beam numbers (beam numbers ‘b’ and ‘c’) is provided and the superior beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number ‘e’) is provided within the predetermined time period for reducing the signaling amount for providing beam number notification.

    摘要: A MIMO transmitting apparatus that achieves a flexible control in accordance with variation of a propagation environment to reduce the number of retransmissions is disclosed. An intra-code-word interleaver performs an interleave process on bits included in symbols to be simultaneously transmitted from a plurality of transmitting antennas. When performing the intra-code-word interleave process, the intra-code-word interleaver performs the interleave process in accordance with an interleave pattern notified from an interleave pattern table. A counter counts a number of retransmission requests, and outputs the number of retransmission requests to the interleave pattern table. The interleave pattern table stores interleave patterns to be used for the intra-code-word interleave process for the respective numbers of retransmission requests, and notifies the intra-code-word interleaver of an interleave pattern in accordance with the number of retransmission requests.
