    摘要: 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.

    摘要: 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.
