  • Patent number: 11728875
    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.

  • Patent number: 11714177
    Abstract: In various embodiments, a system for identifying a vertical height of a user equipment using network-side components, instead of device-side components, is described. The system may include a fixed antenna of a node and a processor. The antenna sends a first beam having a first set of beam characteristics and receives a first signal strength indication from the user equipment based upon the first beam. The antenna then sends a second beam having a second set of beam characteristic and receives a second signal strength indication from the user equipment based upon the second beam. The processor may then analyze the first signal strength and the second signal strength to determine the vertical height of the user equipment, such as by a trigonometric calculation based upon an inclination of the beams and various known distances.
