Beamforming coverage optimization in a radio access network in a wireless communications system (wcs)

Abstract

Optimizing beamforming overhead and improving coverage in a radio access network in a wireless communications system (WCS) is disclosed. Herein, a radio node(s) is configured to radiate multiple radio frequency (RF) beams in a coverage area. Notably, the RF beams can intercept a ground since the radio node(s) is mounted above the ground (e.g., on a ceiling) and facing downward toward the ground. As a result, some of the radiated energy may be wasted to degrade coverage and performance in the coverage area. In this regard, in embodiments disclosed herein, multiple reflector devices (passive and/or active) are provided in proximity to the radio node(s) to intercept the RF beams radiated from the radio node(s) and redirect the intercepted RF beams in parallel to the ground. By redirecting the RF beams horizontally, it is possible to reduce energy waste and enhance beamforming coverage in the radio access network.
