Abstract
Systems and methods of the present disclosure are directed a method performed by a first Ultra-Wideband (UWB)-equipped device for reducing UWB power consumption. The method includes, for a plurality of ranging rounds in accordance with a first ranging time interval, sending one or more UWB ranging signals to a second UWB-equipped device and receiving one or more location measurements from the second UWB-equipped device. A location measurement is indicative of a location of the second UWB-equipped device. The method includes, based on the one or more location measurements across the plurality of ranging rounds, modifying the first ranging time interval to a second ranging time interval different than the first ranging time interval.

Ultra-Wideband (UWB) processing circuitry configured to:
- for a plurality of ranging rounds in accordance with a first ranging time interval:
- send one or more UWB ranging signals to a UWB-equipped device;
- and
- receive one or more location measurements from the UWB-equipped device, wherein a location measurement is indicative of a location of the UWB-equipped device;
- and
- based on the one or more location measurements across the plurality of ranging rounds, modify the first ranging time interval to a second ranging time interval different than the first ranging time interval.
A method, comprising:
- for a plurality of ranging rounds in accordance with a first ranging time interval:
- sending one or more UWB ranging signals to a UWB-equipped device;
- and
- receiving one or more location measurements from the UWB-equipped device, wherein a location measurement is indicative of a location of a second UWB-equipped device;
- and
- based on the one or more location measurements across the plurality of ranging rounds, modifying the first ranging time interval to a second ranging time interval different than the first ranging time interval.
