Abstract: Disclosed are systems, devices and methods for determining a range between devices based, at least in part, on measurements of wireless tone signals transmitted between devices. In particular, two devices may measure tone signals transmitted between the two devices for determination of a round-trip phase measurement. Obtaining multiple round-trip measurements from tone signals transmitted at different carrier frequencies may enable resolving at least some range ambiguities.

Abstract: Embodiments relate to a deployment of a master radio in conjunction with one or more slave radios. The master radio coordinates with a UE, or transmitter, to transmit a particular known set of wireless signals in a defined time window over a dedicated wireless connection between the UE and the master radio. The master radio separately coordinates with the one or more slave radios to monitor for and measure the dedicated wireless connection during the defined time window (e.g., to obtain AoA measurements, signal strength measurements, etc.). The measurements can be reported to the master radio or a separate measurement processing unit to facilitate a location determination of the UE.

Abstract: A method for handover of a set of wireless devices is described. The method includes receiving, at a first wireless device of the set of wireless devices, data from a first serving device of a set of serving devices. The first wireless device has a primary wireless device role and a second wireless device has a non-primary wireless device role. The method includes determining, at the first wireless device, a handover condition for the set of wireless devices. The set of wireless devices is handed over as a set to a second serving device. The method includes becoming detectable, by the first wireless device. Each of the wireless devices in the set of wireless devices is configured to become detectable in response to the handover condition. The method includes receiving, by the first wireless device, an indication of a selected wireless device of the set of wireless devices.
