摘要： Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unit 16 determines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.

摘要： A mobile station wherein the power consumption can be suppressed. In a frame 3, this mobile station (100) transmits, to both a base station (200) and a relay station (150), a multicarrier signal comprising a plurality of subcarriers that have been controlled in transmission power on the basis of reception quality information 1 (Processes (3) and (3)′: first transmission).

摘要： A wireless transmission apparatus capable of suppressing a reduction in coverage area of a base station apparatus and improving the transmission rate in the coverage area. According to this apparatus, a mobile station (10) generates a transport signal addressed to a base station (30) and transmits it to a plurality of relay stations (20-1,20-2), each of which then generates a relay signal from the transport signal and transmits the relay signal to the base station (30). A relay instructing part (115) of the mobile station (10) decides first and second different instructions having their respective instruction contents for the generation of the relay signals. The relay instructing part (115) then sends the first instruction to the relay station (20-1), which is one of the plurality of relay stations (20-1,20-2), while sending the second instruction to the relay station (20-2), which is another one of the plurality of relay stations (20-1,20-2).

摘要： A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station incorporating this wireless receiving apparatus, a selecting part selects a plurality of the same symbols in accordance with a mapping pattern established at the time of generating OFDM symbols in a base station. A correlation value calculating part determines correlation values between the subcarriers of the same symbols to generate an R-matrix, and further determines an inverse matrix of the R-matrix. An MMSE processing part performs an MMSE processing to determine a weight from both a P-vector received from a channel estimating part and the inverse matrix of the R-matrix received from the correlation value calculating part. Multipliers multiply each of the symbols selected by the selecting part by the weight determined by the MMSE processing part. A combining part combines the symbols as multiplied by the weight.

摘要： A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.
