Abstract
Aspects of the present disclosure provide a dual phase-locked loop (PLL) system configured to execute parallel, time shifted ranging session scheduling even if the sessions use different communication channels. Using techniques described herein, in some embodiments, a delay between ranging sessions is reduced compared to other UWB session scheduling implementations, which allows for more compact scheduling and often more accurate measurements as a result.
Claims20
A communication node, comprising:
- an ultra-wideband (UWB) communication unit configured to initiate UWB communication with an external communication node;
- a clock generation system configured to generate at least two different clock signals;
- and
- a processor configured to execute interleaved ranging sessions between the communication node and the external communication node based on the at least two different clock signals, wherein the interleaved ranging sessions comprise two or more distance measurements based on messages exchanged between the communication node and the external communication node, wherein the messages are exchanged through the UWB communication unit.
A non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate at least one processor to:
- initiate ultra-wideband (UWB) communication with an external communication node;
- generate at least two different clock signals;
- and
- execute interleaved ranging sessions between the communication node and the external communication node, wherein the interleaved ranging sessions comprise two or more distance measurements based on messages exchanged between the communication node and the external communication node.
A method of operating a communication node, comprising:
- initiating ultra-wideband (UWB) communication with an external communication node;
- generating at least two different clock signals;
- and
- executing interleaved ranging sessions between the communication node and the external communication node, wherein the interleaved ranging sessions comprise two or more distance measurements based on messages exchanged between the communication node and the external communication node.
