Described is an apparatus of an Evolved Node-B (eNB) comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to generate a reference signal transmission for an eNB Transmitting (Tx) beam corresponding with at least a first eNB antenna port having a first polarization and a second eNB antenna port having a second polarization. The second circuitry may be operable to process one or more reporting transmissions carrying at least one of a first signal reception indication for a first UE antenna port and a second signal reception indication for a second UE antenna port. The third circuitry may be operable to determine a transmission hypothesis based upon the one or more reporting transmissions.
