摘要： A MIMO transmitting apparatus for improving the frame timing detection performance in a cell search. In the MIMO transmitting apparatus, a pilot pattern designating part (108) designates a pilot pattern corresponding to a scrambling code and sends the designation to pilot inserting parts (110-1 to 110-4). The pilot inserting parts (110-1 to 110-4) each insert pilot symbols in accordance with the designation of the pilot pattern designating part (108) into predetermined positions of a respective stream. A scrambling pattern designating part (112) designates a scrambling pattern, i.e., a pattern of reversing the signs of the subcarriers of the pilot symbols in each stream and sends the designation to scrambling parts (114-1 to 114-4). The scrambling parts (114-1 to 114-4) reverse the signs of a half number of subcarriers corresponding to the end or front symbols of the streams in accordance with the designation of the scrambling pattern designating part (112).

摘要： A communication device which can reduce amount of control information, limit interference with other traffics, and prevent an increase in current consumption. In this device, a separation unit (105) separates radio resource allocation information, specific section information and transmission parameter information from a received signal. A specific section information control unit (106) selects a sub-carrier designated by the specific section information to allocate data to be transmitted to the own unit. A channel quality measuring unit (107) uses a pilot signal to measure the channel quality of the selected sub-carrier. A channel quality information creating unit (108) creates channel quality information indicating the measurement results input from the channel quality measuring unit (107). A multiplexing unit (109) multiplexes the transmission signal with the channel quality information.

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.

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 transmitting apparatus, a receiving apparatus and a transmission power control method wherein even in a case of performing a transmission power control of multi-valued modulated symbols, the degradation of reception characteristic and that of network usage efficiency can be avoided. A power control instructing part (204) adjusts, based on an encoding rate and a modulation scheme in a case of applying a power control value, which maximizes the MIMO channel capacity, to each stream, the power control value of a stream, which is the most likely to be affected by a power estimation error, into a reference value, and then applies the adjustment value used for that adjustment to the other streams, that is, the streams that are not likely to be affected by the power estimation error. A power control part (205) performs a transmission power control in accordance with the power control value as adjusted by the power control instructing part (204).

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： A wireless communication apparatus that allows channel information to be reproduced with high precision at a transmitting end without increasing feedback information amount. In this apparatus, a channel estimating part (103) uses received pilot signals to perform channel estimation for each channel. A correlation detecting part (104) uses the result of the channel estimation to obtain correlation values between the channels, thereby detecting correlation values of all channels.
