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.

A terminal comprising:
- 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;
- and
- circuitry, which, in operation:
- estimates power of a signal from the macro-cell base station as an interfering-signal power based on a measurement subframe pattern, a transmission pattern of an almost blank subframe (ABS) set in the macro-cell base station being identical to the measurement subframe pattern;
- 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.
A communication method comprising:
- receiving 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;
- estimating power of a signal from the macro-cell base station as an interfering-signal power based on a measurement subframe pattern, a transmission pattern of an almost blank subframe (ABS) set in the macro-cell base station being identical to the measurement subframe pattern;
- generating a reception weight based on the interfering-signal power;
- and
- separating the plurality of data signals from each other based on the reception weight.
