Abstract: Selective radiation of radio frequency (RF) reference beams in a wireless communications system (WCS) based on user equipment (UE) locations is disclosed. The WCS may include a radio node that communicates RF communications signals in a coverage area via RF beamforming. Thus, the radio node is required to periodically radiate a number of RF reference beams in different directions of the coverage area to help UEs to identify a best-possible RF beam(s). However, radiating the RF beams in different directions periodically can increase power consumption of the radio node, particularly when the UEs are concentrated at a handful of locations in the coverage area. In this regard, the radio node can be configured to selectively radiate a subset of the RF reference beams based on a determined location(s) of the UE(s) in the coverage area, thus making it possible to reduce computational complexity and power consumption of the radio node.
