Abstract

A control unit of a communication device provides multicast precoding information from at least first beamforming information descriptive for a first transmission channel and second beamforming information descriptive for a second transmission channel. A precoder unit beamforms at least one signal using the multicast precoding information to obtain at least two precoded signals. A transmitter circuit which is electrically coupled to the precoder unit multicasts transmission signals through the at least first and a second transmission channels, wherein the transmission signals are derived from the precoded signals.
