Abstract

Disclosed is a method and corresponding devices and computer programs for determining antenna weights for transmissions with punctured signals. The method comprises extracting, from a signal reception model for signals transmitted by at least two communication units, at least one of the communication units transmitting with punctured signals, a signal orthogonality loss quantity introduced by the punctured signals. The method also comprises calculating, based on the extracted signal orthogonality loss quantity, a covariance matrix quantifying the signal orthogonality loss between signals transmitted by the at least two communication units. The method also comprises determining, based on the covariance matrix, antenna weights for data symbols in the signals. Also disclosed is a method and corresponding devices and computer programs for designing a beamformer based on the determined antenna weights, wherein the beamformer suppresses the interference caused by a signal orthogonality loss induced by the transmission of punctured signals.
