摘要： A base-station apparatus (101) and a terminal apparatus (102) communicate with each other in a communication system. When reporting reception quality information together with data to the base-station apparatus via a channel for use in data transmission, the terminal apparatus reports the reception quality information using a spatial multiplexing method identical to a spatial multiplexing method of the data if the reception quality information is reception quality information that is to be nonoperiodically reported, and reports the reception quality information using a spatial multiplexing method independent of the spatial multiplexing method of the data if the reception quality information is reception quality information that is to be periodically reported. When extracting the reception quality information reported together with the data from the terminal apparatus, the base-station apparatus extracts the reception quality information based on the assumption that the spatial multiplexing method of the reception quality information is identical to the spatial multiplexing method of the data if the reception quality information is nonoperiodically reported, and extracts the reception quality information based on the assumption that the spatial multiplexing method of the reception quality information is independent of the spatial multiplexing method of the data if the reception quality information is periodically reported.

摘要： A terminal device includes communication means for carrying out communication with a base station device, and generation means for generating a rank indicator specifying a preferred rank, first partial precoder information and second partial precoder information specifying a preferred precoder, and a reception quality indicator specifying a preferred transmission rate. In a first feedback mode in which reception quality information is reported periodically to the base station device, the communication means reports the second partial precoder information and the reception quality indicator at first timing, and reports the rank indicator and the first partial precoder information at second timing different from the first timing. In a second feedback mode in which the reception quality information is reported aperiodically to the base station device, the communication means reports the rank indicator, the first partial precoder information, the second partial precoder information, and the reception quality indicator at the same timing.

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： A wireless communication system includes a first channel state measurer and a second channel state measurer. When a second communication device measures a state of a channel between the second communication device and a first communication device using reference signals transmitted from the first communication device, the first channel measurer is configured to measure a state of the channel including an interference due to a signal transmitted from another first communication device. When measuring the state of the channel between the second communication device and the first communication device using the reference signals transmitted from the first communication device, the second channel state measurer measures the state of the channel while suppressing the interference due to the signal transmitted from the another first communication device. Accordingly, the wireless communication system can generate adequate feedback information both when cooperative communication is performed and when cooperative communication is not performed.
