  • Publication number: 20250125934
    Abstract: This disclosure provides methods, components, devices and systems for reducing out-of-band emission (OOBE) for transmissions associated with a distributed resource unit (RU) (dRU) allocation. Some aspects more specifically relate to introducing more unevenness in terms of tone spacing to a first subset of dRUs associated with a given bandwidth and maintaining relatively more even tone spacing for a second subset of dRUs associated with that given bandwidth. In some implementations, for example, a complete set of dRUs associated with a bandwidth may include a first subset of dRUs and a second subset of dRUs, with dRUs of the first subset having more uneven tone spacings as compared to dRUs of the second subset. In some aspects, the first subset of dRUs may include dRUs associated with relatively fewer tones as compared to dRUs of the second subset.

  • Publication number: 20230237702
    Abstract: The method includes a data collection step, a setup step, a positioning step, an analysis step, and an adjustment step. The data collection step collects spatial data about a scene to be monitored. The setup step installs a number of monitoring devices and a reference device, where the reference device includes a reflector or a calibration pattern. The positioning step determines respective positions of the monitoring devices relative to the reference device. The analysis step determines whether the FOVs of the monitoring devices jointly cover the scene by an algorithm module analyzing the scene data, the FOVs of the monitoring devices, and the relative positions of the monitoring devices against the reference device. The adjustment step provides suggestions about adding one or more monitoring devices or changing positions of the monitoring devices to cover the scene entirely if the FOVs of the monitoring devices do not cover the scene.
