Abstract: A wireless device may coordinate UWB channel usage with neighboring devices. In some embodiments, an initiator may periodically send an ultra-wideband acquisition packets (UWB-AP). The UWB-AP may comprise information of future UWB channel usage of the initiator. Neighboring UWB devices may receive the UWB-AP and adjust channel usage based on the UWB-AP.

Abstract: In order to eliminate the reliance of ultra-high bandwidth (UWB) standalone transceivers and narrow-band-assisted (NB-assisted) UWB transceivers on BLUETOOTH™ (BLE) usage, an NB radio may be used. The NB radio may be tightly coupled with the UWB radio, for example driven by the same time source, to enable leveraged use of ACP (Acquisition Packet) for discovery, session setup, and maintenance over UWB and/or NB-assisted UWB without the use of BLE. Rules for advertising ACP and scanning for ACP may be defined for two modes of operation. An ad-hoc discovery may be based on external acquisition triggers, while a managed discovery may be based on an ongoing discovery advertisement process. ACPs may thereby be transmitted over UWB and/or NB.

Abstract: A wireless device may use UWB communications in connection-oriented mode to transmit data. In some embodiments, data subframes may be introduced into a MAC frame. In some embodiments, the data subframes contain a LL packet wrapped with its own delimiter, Data Message Payload information element, and frame check sequence. In some embodiments, the data subframes may also include a duplicated MAC header.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. One mobile device acting as a beacon device can define a ranging round including an initial timeslot and a plurality of non-overlapping response slots for discovering and performing ranging with any mobile device in a vicinity of the beacon. The beacon can broadcast a ranging request including a beacon device identifier at a request time. A first mobile device can transmit a first acknowledgement message during a first response slot. A second mobile device can transmit a second acknowledgement message during a second response slot. The beacon device can calculate a first distance from the first mobile device and a second distance from the second mobile device based at least upon information in the first and second acknowledgement messages.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. Ranging between multiple mobile devices can present challenges due to clock drift between the devices resulting in missed messages due to collisions between ranging messages. Techniques can be implemented to reduce the number of collisions by designating time slots for ranging sessions based on timing from a coordinator mobile device. Alternative techniques allow for splitting up channels at different time amount different pairs of devices. The ranging techniques can be used to share information between devices with a predefined distance for applications such as augmented reality.

Abstract: An electronic device configures two or more virtual responders associated with different subsets of capabilities of a physical responder in the electronic device, where the physical responder comprises a radio-frequency (RF) transceiver and multiple antennas, and where a given virtual responder corresponds to the RF transceiver and a given antenna. Then, the electronic device performs, based at least in part on wirelessly communication with a second electronic device and using at least the virtual responders, measurements on wireless signals from the second electronic device to the electronic device, where the measurements correspond to a time of flight of the wireless signals. Next, the electronic device determines, based at least in part on the measurements, a range between the electronic device and the second electronic device, where the determination uses the measurements from different virtual responders to correct for an environmental condition and/or increase an accuracy of the determined range.

Abstract: Methods performed by a first device. The methods include transmitting a first ranging poll to a plurality of second devices, receiving a polling response message from each of at least a first subset of the second devices, determining a propagation delay for each of the received polling response messages and determining a distance to each of the first subset of the second devices based on at least the respective propagation delays. The methods further include receiving a ranging poll from a second device, wherein the ranging poll is one of a multicast transmission or a broadcast transmission, determining a type of response to be transmitted to the second device based on at least a capability of the first device and transmitting a response of the determined type to the second device.

Abstract: A mobile device may receive a plurality of polling messages with each polling message including an identifier of a particular access device transmitting the polling message. Each polling message of the plurality of polling messages may be transmitted during a polling phase. The mobile device may select a timeslot of a response phase of a communication session. The mobile device may transmit a response message during the timeslot of the response phase. The mobile device may receive, during a third phase, an assignment message including an assigned timeslot for a response phase of a future session. The mobile device may perform secure ranging with one or more access devices of the plurality of access devices during the future session using the assigned timeslot. The mobile device may provide an access credential to the one or more access devices based on a location determined using the secure ranging.
