  • Patent number: 11936451
    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.

  • Patent number: 11736175
    Abstract: Grid of beams (GoB) adaptation in a wireless communications circuit, particularly for a wireless communications system (WCS), is disclosed. The wireless communications circuit may be provided in the WCS to provide radio frequency (RF) coverage in a wireless communications cell. In this regard, an antenna array is provided in the wireless communications circuit to radiate the GoB, which includes a number of RF beams corresponding to an RF communications signal(s), in the wireless communications cell. In examples discussed herein, the wireless communications circuit can be configured to detect a coverage condition change in the wireless communications cell and modify the GoB accordingly.

  • Patent number: 10785800
    Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.
