Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first subsystem of a first device may determine parameter data for a ranging round (e.g., UWB and/or NB-assisted (NBA) UWB multi-millisecond (MMS) ranging), and transmit the parameter data to a second subsystem of the first device. The parameter data may indicate a first time associated with a first time domain for performing ranging. The second subsystem may determine a second time based on the first time, whereby the second time is associated with a second time domain for performing NB signaling (e.g., via a Bluetooth Low Energy (BLE) protocol). The first device may transmit via an NB signal an advertisement packet that indicates the second time. The first device may then initiate the ranging round at the first time.

Systems, methods, and computer-readable medium are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. For example, a first device may schedule transmission of a packet via a narrowband signal to a second device. The first device may then transmit the packet, whereby the packet conveys synchronization data that is used by the second device to schedule reception of a plurality of fragments, respectively, via an ultra-wideband (UWB) signal. The first device may then schedule and transmit the plurality of segments to the second device via the ultra-wideband signals, each fragment being time-spaced from other fragments of the plurality of fragments by at least a predefined time interval.

Techniques for hybridized ultra-wideband and narrowband signaling

Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first device may transmit a first packet via an NB signal to a second device, whereby the first packet comprises information indicating to the second device a time period for reception of a second (UWB) packet. In this example, the second packet may comprise a first partition and a second partition, whereby the first partition comprises a first plurality of fragments and the second partition comprising a second plurality of fragments. The respective fragments of each plurality of fragments may be transmitted via a UWB signal. The first device may then transmit the first plurality of fragments, and then subsequently transmit the second plurality of fragments to the second device, the first and second pluralities respectively being associated with different fragment types.

Signaling techniques using fragmented and multi-partitioned UWB packets

Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for passive beacon communication techniques. Transmitting devices (e.g., beacons) can transmit advertising messages using a first wireless protocol to provide timing for ranging messages for one of more ranging messages over a second protocol (e.g., UWB). One or more receiving devices can determine using signal strength if the devices are within a threshold range to perform communication techniques. Various ranging communications techniques can be used to determine a range between the receiving device and transmitting device. Other techniques can be used to passively calculate the angle of arrival for transmitter signals. The angle of arrival information can be used for precise position locating for the receiving device or to indicate interest in information provided by the one or more transmitting devices.

Communication techniques using passive beacons

Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. For example, a first device may transmit a packet via an NB signal to a second device, whereby the packet comprises information indicating a time period for reception of a plurality of fragments, respectively, via a UWB signal. The first device may then transmit a first fragment of the plurality of fragments to the second device via the UWB signal, whereby the first fragment comprises an intermediary base sequence, the intermediary base sequence being aperiodic and comprising a first set of first sequences and a second set of second sequences. In some embodiments, the intermediary base sequence may contain at least one gap interval that may be used to identify a signature of the link between the first device and the second device.
