Abstract
Systems and methods of the present disclosure are directed to 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.
Claims19
An Ultra-Wideband (UWB)-equipped device with reduced UWB power consumption, comprising:
- one or more UWB transmitters;
- one or more UWB receivers;
- processing circuitry, wherein the processing circuitry is configured to cause the UWB-equipped device to:
- for a plurality of ranging rounds in accordance with a first ranging time interval:
- send one or more UWB ranging signals to a second UWB-equipped device;
- and
- receive one or more location measurements from the second UWB-equipped device, wherein a location measurement is indicative of a location of the second UWB-equipped device;
- determine, based on the one or more location measurements across the plurality of ranging rounds, a current location and a predicted end location for the second UWB-equipped device;
- make a determination whether the predicted end location is within a range of interest;
- 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, wherein modifying the first ranging time interval comprises modifying, based on the determination, the first ranging time interval to the second ranging time interval different than the first ranging time interval.
An Ultra-Wideband (UWB)-equipped device with reduced UWB power consumption, wherein the UWB-equipped device is adapted to:
- for a plurality of ranging rounds in accordance with a first ranging time interval:
- send one or more UWB ranging signals to a second UWB-equipped device;
- and
- receive one or more location measurements from the second UWB-equipped device, wherein a location measurement is indicative of a location of the second UWB-equipped device;
- determine, based on the one or more location measurements across the plurality of ranging rounds, a current location and a predicted end location for the second UWB-equipped device;
- make a determination whether the predicted end location is within a range of interest;
- 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, wherein modifying the first ranging time interval comprises modifying, based on the determination, the first ranging time interval to the second ranging time interval different than the first ranging time interval.
A method performed by a first Ultra-Wideband (UWB)-equipped device for reducing UWB power consumption, comprising:
- 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, wherein a location measurement is indicative of a location of the second UWB-equipped device;
- determining, based on the one or more location measurements across the plurality of ranging rounds, a current location and a predicted end location for the second UWB-equipped device;
- making a determination whether the predicted end location is within a range of interest;
- 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, wherein modifying the first ranging time interval comprises modifying, based on the determination, the first ranging time interval to the second ranging time interval different than the first ranging time interval.
