TRANSMISSION APPARATUS AND METHOD

摘要

A transmission apparatus which allocates a signal to a stream, performs precoding to cancel interference at an n-th reception apparatus, and performs a modulo operation for controlling the transmission power to within a predetermined value. The processing for allocating a signal to a stream allocates an n-th signal to an x-th stream, wherein in said n-th signal, the size of the sum of the absolute values of the feedback coefficients for cancelling interference at an n-th reception apparatus after allocation of a signal to an (x-1)-th stream is less than or equal to a second threshold value or is the minimum value.
