Multi-beamwidth radio frequency (rf) beamforming optimization in a wireless communications apparatus, particularly for a wireless communications system (wcs)

Abstract

Multi-beamwidth radio frequency (RF) beamforming optimization in a wireless communications apparatus is disclosed. The wireless communications apparatus includes a signal processing circuit configured to process an RF communications signal for radiation in a set of RF beams optimized to maximize coverage in a wireless communications cell. In examples disclosed herein, the set of RF beams includes a center RF beam and a number of edge RF beams. Specifically, the center RF beam is formed with a wider beamwidth to cover a larger center area of the wireless communications cell and, the edge RF beams are each formed with a narrower beamwidth to improve coverage in an edge area of the wireless communications cell. As a result, it may be possible to maximize coverage in the wireless communications cell with fewer RF beams, thus helping to reduce computational complexity, processing latency, and energy consumption of the wireless communications apparatus.
