Abstract: The disclosure includes a method for providing a data link between one or more high frequency Transmission Points (TPs) and a User Equipment (UE) in a wireless network, the method including receiving, by the UE, an assignment from a macro cell in the heterogeneous wireless network, wherein the assignment includes a UE specific reference signal set that maps to one or more high frequency TP downlink beams. The UE identifies each of the one or more TP downlink beams by detecting the UE specific reference signals sent in each of the one or more TP downlink beams. The UE measures a quality of each of the one or more TP downlink beams and selects a selected beam from the one or more TP downlink beams based on the quality. The UE establishes the data link to the high frequency TP that transmitted the selected beam using the selected beam.
