Abstract: Methods and apparatus for processing positioning assistance data are provided. An exemplary method includes receiving, from a positioning server, virtual access point (VAP) data including a list of unique identifiers, and determining a location of a mobile device by using the VAP. The VAP data indicates that the unique identifiers included on the list identify signals originating from the same physical access point. The unique identifiers can be MAC addresses. In an example, the location determining the can include actively scanning a signal identified by a unique identifier on the list and not actively scanning a different signal identified by a different unique identifier also on the list. Not scanning the other MAC addresses that are on the access point's list and assigned to the mobile device keeps the mobile device from performing duplicative scanning that wastes time, processor cycles, and energy.

Abstract: A method for aligning visual-inertial odometry (VIO) and satellite positioning system (SPS) reference frames includes obtaining a plurality of range-rate measurements of a mobile platform from an SPS. The range-rate measurements are with respect to a global reference frame of the SPS. The method also includes obtaining a plurality of VIO velocity measurements of the mobile platform from a VIO system. The VIO velocity measurements are with respect to a local reference frame of the VIO system. At least one orientation parameter is then determined to align the local reference frame with the global reference frame based on the range-rate measurements and the VIO velocity measurements.

Abstract: Disclosed are implementations that include a method, performed by a network control device, including sending a first instruction to a first device to send a first measurement signal, and sending a second instruction to a second device to receive the first measurement signal. Following receipt of a first acknowledgement signal from the target mobile device, the first and second devices change their roles so the second device sends, and the first device receives, a second measurement signal, and the first and second devices receive a second acknowledgement signal from the target device. Position of the target device is determined based on timing measurements associated with the first and second measurement signals, the first and second acknowledgement signals, and on known positions of the first and second devices. Another network device is selected to perform additional measurements upon a determination that a desired accuracy of the position determined was not achieved.

Abstract: Disclosed are systems, apparatus, devices, methods, media, products, and other implementations, including a method that includes determining, at a first wireless device comprising multiple transmit antennas, at least one signal transmission characteristic according to at least one pre-determined varying transmission characteristic determination process. The at least one transmission characteristic includes, for example, a transmit antenna selected from the multiple transmit antennas, a beam characteristic, a cyclic delay diversity parameter, and/or any combination thereof. The method also includes transmitting from the first wireless device to a second wireless device a signal using the at least one signal transmission characteristic determined according to the at least one pre-determined varying transmission characteristic determination process. The transmitted signal is configured to facilitate position determination of the second wireless device upon deriving at the second wireless device a reconstructed value of the at least one signal transmission characteristic determined at the first wireless device.

A method according to these techniques includes receiving, at a mobile device, information defining a boundary defined by first and second fixed-location WAPs, the boundary being defined at least in part based on a ratio of a round trip time (RTT) between the mobile device and the first fixed-location WAP to a ratio of a RTT between the mobile device and the second fixed-location WAP, determining the ratio of the RTT between the mobile device and the first fixed-location WAP to a ratio of the RTT between the mobile device and the second fixed-location WAP, determining whether the mobile device has crossed the boundary, and triggering an event in response to the mobile device crossing the boundary.
