RECIPROCITY-AIDED ITERATIVE BEAMSPACE INTERFERENCE SUPPRESSION

Abstract: according to some embodiments, a method performed by a network node for interference aware downlink transmission includes determining a reciprocity-aided interference aware transmission precoder based on a downlink wideband interference covariance matrix estimated from a plurality of received sounding reference signals and based on a matrix inversion associated with the downlink wideband interference covariance matrix. the matrix inversion is determined based on an iterative inverse covariance estimation. the method further includes transmitting a downlink signal using the reciprocity-aided interference aware transmission precoder.
