Claim 23:
24. A first wireless device, comprising:
processing circuitry configured to:
receive beamformed channel state information-reference signal, CSI-RS, signaling, the beamformed CSI-RS signaling being communicated based on a common precoding matrix index, PMI, that the common PMI comprising a common beamforming vector which is not in any of at least one null space associated with a plurality of wireless devices including the first wireless device;
compute a channel quality indicator, CQI, based on the beamformed CSI-RS signaling; and
indicate the CQI that is based on the beamformed CSI-RS signaling to a network node.
