  • Publication number: 20230387970
    Abstract: Multi-beam uniform coverage in a coverage cell(s) in a wireless communications system (WCS) is provided. The WCS includes a number of wireless devices that are typically mounted on a fixed structure to provide coverage for user devices. Each wireless device includes one or more antenna arrays. Each antenna array is controlled via a set of codewords to form one or more RF beams to each cover a respective area in a coverage cell. The codewords are predetermined based on fairness and/or leakage constraints such that the RF beams can be formed in desired geometric shapes and steered toward desired directions to provide a unform coverage in the coverage cell. By forming the RF beams based on the codewords predetermined based on fairness and/or leakage constraints, it is possible to ensure an equal RF power signal level inside the coverage cell and/or reduced power leakage outside the coverage cell.

  • Publication number: 20230379035
    Abstract: Multi-level beam scheduling in a wireless communications circuit, particularly for a wireless communications system (WCS), is disclosed. The WCS includes a central unit(s) and a wireless communications circuit(s) configured to reduce beamforming overhead and improve radio frequency (RF) coverage in a wireless communications cell(s) based on a multi-level beam scheduling scheme. In a non-limiting example, the multi-level beam scheduling scheme includes a first level (L1) scheduler, a second level (L2) scheduler, and a third level (L3) scheduler configured to perform cross-cell beam scheduling, in-cell beam scheduling, and in-beam user equipment (UE) scheduling, respectively. By employing the multi-level beam scheduling scheme in the WCS, it may be possible to reduce processing overhead and improve resource usage, data throughput, and system adaptability of the wireless communications circuit(s), thus helping to optimize capacity and throughput in the wireless communications cell(s).

  • 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. By adapting the GoB to the coverage condition change, it may be possible to reduce processing overhead and improve resource usage, data throughput, and system adaptability of the wireless communications circuit, thus helping to optimize RF coverage in the wireless communications cell.

  • Publication number: 20220385312
    Abstract: Intelligent thermal and power management in a wireless communications device in a wireless communications system (WCS) is disclosed. In a non-limiting example, the wireless communications device can be a base station (e.g., eNB) in the WCS. The wireless communications device includes a number of sensor circuits each configured to perform a sensory measurement (e.g., temperature measurement) in a specific circuit or at a specific location of the wireless communications device. A control circuit is provided in the wireless communications device support intelligent thermal and power management in the wireless communications device. Specifically, the control circuit determines that the sensory measurement is above an abnormal threshold(s) and performs one or more corrective actions accordingly to reduce the sensory measurement to a desirable threshold.

  • Publication number: 20220386235
    Abstract: Dynamic power saving in a wireless device in a wireless communications system (WCS) is disclosed. The WCS includes a wireless device(s), such as a fifth-generation (5G) or a 5G new-radio (NR) base station (eNB), configured to communicate downlink and uplink communications signals in a coverage cell. In embodiments disclosed herein, the wireless device(s) can determine whether a power-saving condition is met in the coverage cell, and opportunistically operate in a power-saving mode when the power-saving condition is met. By opportunistically operating in the power-saving mode based on the power-saving condition, it is possible to reduce power consumption in the wireless device(s) without sacrificing user experience in the coverage cell.

  • Publication number: 20220385367
    Abstract: Dynamic radio frequency (RF) beam pattern adaptation in a wireless communications system (WCS) is provided. The WCS typically includes a number of wireless devices, such as remote units and/or base stations, for enabling indoor wireless communications to user devices. The wireless devices are typically mounted on a fixed structure. Notably, a wireless device may be preconfigured to support RF beamforming based on an RF beam pattern that corresponds to a configured orientation. However, the wireless device can be installed with a different orientation from the configured orientation, thus requiring the RF beam pattern to be adapted accordingly. In this regard, a wireless device is configured to dynamically determine an actual orientation of the wireless device and automatically adapt the RF beam pattern based on the determined actual orientation. As a result, it is possible to reduce installation and calibration time associated with deployment of the wireless device in the WCS.
