摘要： In a transmission apparatus which multicarrier-modulates and transmits symbols, which are basic units of digital signals, a subcarrier in which a symbol is arranged in a first multicarrier symbol having a first guard interval and a subcarrier in which a symbol is arranged in a second multicarrier symbol having a second guard interval longer than the first guard interval are scattered among a plurality of subcarriers constituting a multicarrier at the same time. Therefore, it is possible to improve the resistance to inter-symbol interference without substantially degrading transmission efficiency.

摘要： To provide a receiving apparatus and reception method that can reduce degradation due to multipath interference without increasing the amount of computation even in a system that has a large number of subcarriers.
A signal detector 205, using the symbol replica generated by symbol replica generator 208 and the channel estimate which a channel estimator 209 estimated based on the received pilot signal, suppresses interference attributed to delayed waves exceeding the GI and outputs a suppressed signal for the receivedsignal. Ademodulator 206 decodes the signal of which interference has been alleviated, to determine code bit LLR as bit likelihood information. A decoder 207 performs an error correction decoding process on the input code bit LLR. If no error exists in the result of error correction decoding, the decoder outputs information bits to complete the reception process. If there is an error in the decoded result, the decoder outputs the code bit LLR to symbol replica generator 208.

A terminal device receives a first reception signal and a second reception signal, includes a higher layer processing unit that determines NAICS information indicating whether it is indicated in a higher layer that NAICS has to be applied, and a control unit that performs control in such a manner that, in a case where the NAICS is configured in the higher layer, an ACK/NACK of the first reception signal is transmitted and an ACK/NACK of the second reception signal is not transmitted. Furthermore, configuration information of the terminal device is acquired in the higher layer, downlink control information is received using a downlink control channel, and, with the first reception signal, signal detection is performed using information that is obtained from the configuration information and the downlink control information, and with the second reception signal, the signal detection is performed based on the configuration information.
