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. A buffer (104) temporarily stores transport bits, which have been interleaved, in preparation for retransmission. An intra-code-word interleaver (105) performs an interleave process by all of the bits included in the symbols to be simultaneously transmitted from a plurality of transmitting antennas. When performing an intra-code-word interleave process, the intra-code-word interleaver (105) performs the interleave process in accordance with an interleave pattern notified from an interleave pattern table (107). A counter (106) counts retransmission requests, and outputs the number of retransmissions to the interleave pattern table (107). The interleave pattern table (107) stores interleave patterns to be used for intra-code-word interleave process for the respective numbers of retransmissions, and notifies the intra-code-word interleaver (105) of an interleave pattern in accordance with a number of retransmissions.

摘要： A transmitter, a receiver and a communication method enabling improvement of the data rate of an MIMO system. One signal x2 out of the three signals is combined with the other two signals x1, x3 respectively to generate two combined signals x1+x2, x2+x3. The combined signals are transmitted through transmission antennas (102, 103). A signal separating section (106) of the receiver separates the received signals r1, r2 into two signals y1, y2 by a signal separation processing such as the ZF. An MLD processing section (107) generates MLD evaluation formulae using y1, y2 and performs an MLD processing in which x2 is cancelled from y1, y2 and evaluation formulae about x1, x3 are generated, and a maximum likelihood estimation is performed. As a result of the MLD processing, x1, x3 are detected. In a canceling section (108) the detected x1, x3 are canceled from y1, y2, and x2 is detected.

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 wireless communication apparatus wherein the power consumption can be reduced. In this apparatus, a code block dividing part (101) divides a transport block, in which filler bits have been inserted, into a plurality of code blocks. A mapping control part (107) controls, based on both scheduling information, which is received from a scheduler (not shown) and indicative of physical channel resources to be used for code block transmission, and the number of filler bits which is received from the code block dividing part (101), the plurality of code blocks so that they will be mapped to the respective physical channel resources in such an order that a respective code block having a less number of filler bits will be mapped to a respective more forward physical channel resource. A mapping part (108) then maps, based on mapping information received from the mapping control part (107), data symbols, which are received from the modulating parts (106) of the respective ones of code block processing parts (102-1 to 102-C), to the physical channel resources.

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.
