摘要： A macro-cell base station (MeNB) transmits, via a PDCCH in a first subframe, both allocation information indicating a radio resource allocated to a radio terminal (MUE) and subframe information indicating a second subframe which is later than the first subframe and in which an allocation is applied in accordance with the allocation information. The radio terminal (MUE) receives the allocation information and the subframe information from the macro-cell base station (MeNB) via the PDCCH in the first subframe. The macro-cell base station (MeNB) omits the transmission of the allocation information in the second subframe, while the reception unit on the terminal side omits the reception of the allocation information in the second subframe.

By using the obtained first prediction filter coefficient, the system executes a first prediction for predicting channel information upon a radio signal transmission in the future and suppresses a component of the ray contained in the low ray element. By using the low ray component in which the ray component is suppressed, the system executes a second prediction for predicting channel information upon a radio signal transmission in the future.

摘要： A channel estimation and prediction unit 18 estimates a channel and predicts a channel for a next transmission slot. An SVD unit 19 performs singular value decomposition on each channel prediction value. An eigenvalue calculation unit 20 calculates an eigenvalue in a slot, whereas an eigenmode quality calculation unit 21 calculates quality of each eigenmode based on the eigenvalue obtained from the eigenvalue calculation unit 20 and outputs the quality to a transmission adaptive control unit 22. The transmission adaptive control unit 22 recognizes frequency of channel variation based on variation of quality of a lower eigenmode and the likes, and corrects quality of a higher eigenmode to be a smaller value according to the frequency of channel variation being larger with respect to a slot length.
