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: An electronic device may receive a first signal from a first transmitting device at a first time. The electronic device may receive a second signal from a second transmitting device at a second time. The electronic device may access location information for the first transmitting device and the second transmitting device. The electronic device may receive a message from a second electronic device having a known distance relationship to the first transmitting device and the second transmitting device, wherein the second electronic device is configured to receive the first signal, the second signal, and the message including timing information of the signals. The electronic device may determine the position of the electronic device using the location information and the timing information, wherein the position is dependent on the known distance relationship.
