A method, system and apparatus are disclosed. According to one or more embodiments, a network node is provided. The network node includes processing circuitry configured to receive channel state information, CSI, from each of a plurality of wireless devices and determine at least one null space based on the received CSI from each of the plurality of wireless devices. The processing circuitry is further configured to determine a common precoding matrix index, PMI, where a common beamforming vector is not in the at least one null space and cause a multicast broadcast transmission to the plurality of wireless devices using at least the common PMI.
