Abstract: Some embodiments include a system and method for enabling communicating Ultra Wideband (UWB) devices to collaborate by exchanging pulse shape information. The UWB devices use the pulse shape information to improve ranging accuracy. The improved ranging accuracy can be used in complex multipath environments where advanced estimation schemes are used to extract an arriving path for time-of-flight estimation. To determine the pulse shape information to be shared, some embodiments include determining location information of a UWB device and selecting the pulse shape information that satisfies regional aspects. The pulse shape information includes a time-zero index specific to a ranging signal that is used by UWB receivers to establish timestamps time-of-flight calculations. Some embodiments include measuring performance characteristics and selecting different pulse shape information based on the performance characteristics for improved accuracy.

Abstract: An apparatus, method and computer readable medium for special thermal density reduction by antenna thinning. A system comprises N transmit/receive (TX/RX) chains, where each TX/RX chain comprises an RFFE and each RFFE comprises one or more thermal sensors configured to measure heat in the RFFE. An antenna array coupled to the plurality of TX/RX chains. A codebook that comprises a plurality of code words configured to respond to real-time heat measurements from the thermal sensors in each TX/RX chain is configured to switch off selected TX/RX chains to reduce thermal density at the antenna array while maintaining M RFFEs switched on, where M

Abstract: 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.

Abstract: 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.

Abstract: 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.

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.
