Abstract: A terminal includes: a receiver, which, in operation, receives a plurality of data signals that is spatially multiplexed, the plurality of data signals being transmitted from a small-cell base station disposed in an area covered by a macro-cell base station; an estimator, which, in operation, estimates power of a signal from the macro-cell base station as interfering-signal power; and a signal separator, which, in operation, generates a reception weight based on the interfering-signal power and separates the plurality of data signals from each other based on the reception weight.

Abstract: A terminal includes: a radio receiver, which, in operation receives a plurality of data signals transmitted from a base station by a multi user-multiple input multiple output (MU-MIMO) scheme, the plurality of data signals being spatially multiplexed; an inter-user interference power estimator, which, in operation estimates inter-user interference power based on a transmission weight of another terminal with which the MU-MIMO scheme is performed; and a signal separator, which, in operation generates a reception weight based on the inter-user interference power and separates the plurality of data signals from each other based on the reception weight.

Abstract: In a base station that transmits data to a first terminal in coordination with a coordination-providing base station, and functions as a connection-making base station that instructs the coordination-providing base station on a transmission parameter that is used for coordinated communication, a reception processor receives first CSI between the connection-making base station and the first terminal from the first terminal, and, receives, from each of at least one or more second terminals other than the first terminal, second CSI between the connection-making base station and a second terminal, and third CSI between the coordination-providing base station and at least one second terminal, a CSI estimator configures the third CSI which corresponds to a terminal, to which the first CSI and the second CSI are the closest, of the at least one or more second terminals, as an estimation value of CSI between the coordination-providing base station and the first terminal.
