Frequency stitching for uwb ranging and sensing

A device for enabling frequency stitching in either or both of ultra-wideband (UWB) ranging or sensing, the device comprising:

• a transceiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• determine capabilities of a UWB initiator device and a UWB responder device related to at least one UWB session, wherein:
• the capabilities comprise information indicative of a capability of each of the UWB initiator device and the UWB responder device for performing radio frequency (RF) retuning during the at least one UWB session, and
• the UWB responder device is configured to take measurements of UWB RF signals transmitted by the UWB initiator device during the at least one UWB session;
• determine a gap duration based at least in part on the capability of each of the UWB initiator device and the UWB responder device for performing RF retuning during the at least one UWB session;
• and
• send a configuration, via the transceiver, to the UWB initiator device, the UWB responder device, or both, wherein the configuration is indicative of:
• a first period of time in the at least one UWB session during which a first portion of the UWB RF signals is transmitted using a first carrier frequency,
• a gap following the first period of time and having a duration of at least the determined gap duration, and
• a second period of time in the at least one UWB session, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.

An apparatus for enabling frequency stitching in either or both of ultra-wideband (UWB) ranging or sensing, the apparatus comprising:

• means for determining capabilities of a UWB initiator device and a UWB responder device related to at least one UWB session, wherein:
• the capabilities comprise information indicative of a capability of each of the UWB initiator device and the UWB responder device for performing radio frequency (RF) retuning during the at least one UWB session, and
• the UWB responder device is configured to take measurements of UWB RF signals transmitted by the UWB initiator device during the at least one UWB session;
• means for determining a gap duration based at least in part on the capability of each of the UWB initiator device and the UWB responder device for performing RF retuning during the at least one UWB session;
• and
• means for sending a configuration to the UWB initiator device, the UWB responder device, or both, wherein the configuration is indicative of:
• a first period of time in the at least one UWB session during which a first portion of the UWB RF signals is transmitted using a first carrier frequency,
• a gap following the first period of time and having a duration of at least the determined gap duration, and
• a second period of time in the at least one UWB session, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.

A non-transitory computer-readable medium storing instructions for enabling frequency stitching in either or both of ultra-wideband (UWB) ranging or sensing, the instructions comprising code for:

• determining capabilities of a UWB initiator device and a UWB responder device related to at least one UWB session, wherein:

• the UWB responder device is configured to take measurements of UWB RF signals transmitted by the UWB initiator device during the at least one UWB session;
• determining a gap duration based at least in part on the capability of each of the UWB initiator device and the UWB responder device for performing RF retuning during the at least one UWB session;
• and
• sending a configuration to the UWB initiator device, the UWB responder device, or both, wherein the configuration is indicative of:
• a first period of time in the at least one UWB session during which a first portion of the UWB RF signals is transmitted using a first carrier frequency,
• a gap following the first period of time and having a duration of at least the determined gap duration, and
• a second period of time in the at least one UWB session, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.
