Systems, methods, apparatuses, and computer program products for GIS-NR beamforming for mmWave. For example, certain embodiments may provide for beam realignment, through which a serving network node may be able to re-position its beam towards a UE without the UE explicitly measuring and signalling to the network node the need for realignment. Instead of performing the traditional UE-based exhaustive beam search, the serving network node may proactively switch the beam in an attempt to track the UE movements. The serving network node may do this by corroborating information from two types of sources: 1) a set of neighbor mobile or fixed network nodes and 2) a geographic information system (GIS).
