Abstract: In some implementations, a mobile device may receive a UWB positioning session configuration message from each of one or more UWB anchor devices. The mobile device may determine to perform hybrid NR/UWB positioning of the mobile device and may initiate the hybrid NR/UWB positioning of the mobile device. Initiating the hybrid NR/UWB positioning of the mobile device may comprise: conducting an NR positioning session with a Location Management Function (LMF) of a NR network and conducting a UWB positioning session with each of at least a subset of the one or more UWB anchor devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a responding device may receive a signal from an initiating device. The responding device may estimate, from the signal, a channel impulse response (CIR) that represents signal reflections from one or more objects as multiple taps. The responding device may select one or more taps, from the multiple taps, that are within a first time window that starts at a first offset from a reference point and that has a first specified time duration. The responding device may transmit, to the initiating device, a CIR report that indicates the one or more taps. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an initiator network node may transmit a first sensing signal for sensing an object using ultra-wideband sensing. The initiator network node may receive, from a responder network node, a second sensing signal, that is based at least in part on the first sensing signal, for sensing the object using the ultra-wideband sensing. The initiator network node may obtain a location of the object relative to the initiator network node and the responder network node based at least in part on the first sensing signal and the second sensing signal.

Abstract: In some implementations, a server may obtain metric information from each of a group of RF positioning anchors, wherein the metric information of a respective RF positioning anchor comprises information regarding: a time source accessible to the respective RF positioning anchor, a ground truth accuracy of a known location of the respective RF positioning anchor, a clock stability of the respective RF positioning anchor, a geographic location of the respective RF positioning anchor, a prevalence of Line of Sight (LoS) links of the respective RF positioning anchor, or power consumption information of the respective RF positioning anchor, or a combination thereof. The server may select the synchronization reference anchor from the group of RF positioning anchors based at least in part on the metric information. The server may transmit information indicative of the selected synchronization reference anchor to each RF positioning anchor of the group of RF positioning anchors.

Abstract: This disclosure provides methods, components, devices and systems for ambient power energizer control. Some aspects more specifically relate to utilizing silent periods during which an energy providing device does not transmit radio frequency (RF) energizing waveform to avoid interference. In some implementations, a reader may transmit a message to an energizer, indicating the time period during which the energizer is to refrain from transmitting the energizing waveform. The reader also may transmit a similar message to one or more tags indicating when the tags should harvest energy and monitor for wakeup signaling. A master device may send coordination information to multiple readers such that each reader and each energizer coordinates silent periods. An energizer may combine multiple patterns of silent time periods to ensure that silent time periods for different readers are aligned. The reader may dynamically trigger energizer waveform transmission.

Abstract: In some implementations, an ultra-wideband (UWB) initiator anchor device may receive a first blink message from a mobile device, wherein: the first blink message is sent during a slot of a contention access period (CAP) in a round of a UWB session, and the first blink message comprises a radio frequency (RF) message configured to enable UpLink Time Difference of Arrival (UL-TDoA) measurements by one or more UWB responder anchor devices. The UWB initiator anchor device may transmit a control message from the UWB initiator anchor device indicating a reserved slot in a subsequent contention free period (CFP) of the UWB session, wherein reserving the slot is responsive, at least in part, to receiving the first blink message at the UWB initiator device from the mobile device.

Abstract: In some implementations, a method may comprise determining capabilities of UWB initiator and responder devices related to at least one UWB session. The method may also comprise determining a gap duration based at least in part on the capabilities of the UWB initiator and responder devices for performing RF retuning during the at least one UWB session. The method may also comprise sending a configuration to the UWB initiator and/or responder devices, 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 of at least the determined gap duration following the first period of time, and a second period of time, following the gap, during which a second portion of the UWB RF signals is transmitted using a second carrier frequency.

Abstract: In some implementations, an ultra-wideband (UWB) management server may send a first message to a UWB anchor, wherein: the first message is indicative of a first threshold to use in a UWB positioning session, the first threshold specifying at least one trigger condition for making available one or more reserved time slots in a Contention Access Period (CAP) of the UWB positioning session. The UWB management server may determine a second threshold for identifying a UWB responder having a respective reserved time slot in the CAP. The UWB management server may send a second message to the UWB anchor, wherein the second message causes the UWB anchor to either: (i) move the respective reserved time slot in the CAP for the UWB responder to a respective one or more time slots in a Contention Free Period (CFP), or (ii) terminate the UWB positioning session with the UWB responder.
