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： Various systems and methods are described for performing fractionally spaced time domain equalization (TEQ). One embodiment is a method implemented in a communication system for training a fractionally spaced time domain equalizer (TEQ). The method comprises performing an initialization phase, averaging a received signal in the system to reduce effects of noise in a channel, determining a channel estimate, and aligning an ideal reference signal with the received signal. The method further comprises updating a target response filter according to a non-integer multiple of a base sampling rate, determining an adaptation error based on useful information both inside and outside a Nyquist band of the TEQ, and updating the TEQ according to the adaptation error.

摘要： It is possible to provide an SC-FDMA transmission device and an SC-FDMA transmission signal formation method which improve the transmission efficiency of the SC-FDMA transmission signal. The SC-FDMA transmission device (100) performs the discrete Fourier transform process on a primary modulation signal sequence formed by N primary modulation symbols to obtain a plurality of frequency components, which are respectively mapped onto different subcarriers. The obtained SC-FDMA symbol is subjected to the inverse Fourier transform process before being transmitted. A propagation path information decoding unit (155) acquires frequency selection characteristic in a propagation path to/from a reception side. A cyclic shift unit (110) and a correlation characteristic judgment unit (115) adjust the frequency response of the SC-FDMA symbol according to the frequency selection characteristic. The adjustment is performed by a result of correlation obtained by performing a correlation calculation between the propagation path frequency selection characteristic and the SC-FDMA symbol.
