Patent number: 11991107Abstract: 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.Type: GrantFiled: November 1, 2021Date of Patent: May 21, 2024Assignee: Apple Inc.Inventors: Joachim S. Hammerschmidt, Eren Sasoglu, Santhoshkumar Mani

Publication number: 20240163006Abstract: A wireless device may transmit ranging transmissions using a compressed PSDU. The compressed PSDU may be configured to support poll packets, response packets, and report packets. The compressed PSDU may comprise an identifier (ID) field, an address field, ID specific data, and a cyclic redundancy check (CRC) field. Further, the wireless device may use an optimized header IE for broadcast.Type: ApplicationFiled: September 15, 2023Publication date: May 16, 2024Inventors: Alexander Krebs, Su Khiong Yong, Moche Cohen, Santhoshkumar Mani, Lochan Verma, Yong Liu, Jinjing Jiang

Publication number: 20240045017Abstract: 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.Type: ApplicationFiled: October 17, 2023Publication date: February 8, 2024Applicant: APPLE INC.Inventors: Joachim S.

Publication number: 20230379655Abstract: 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.Type: ApplicationFiled: August 3, 2023Publication date: November 23, 2023Applicant: APPLE INC.Inventors: Yagil Burowski, Santhoshkumar Mani, Robert W.
