    Abstract: A user equipment (UE) may receive Vehicle-to-Everything (V2X) information from a V2X entity, such as a vehicle, road side unit, or other UE carried by a pedestrian. The V2X information may be transmitted to a location server by the UE to obtain positioning assistance data. The location server may determine a coarse position of the UE using the V2X information and generate corresponding positioning assistance data including Positioning Reference Signal (PRS) information for neighbor base stations, which is transmitted to the UE. The UE may detect PRS signals from the neighbor base stations and perform position determination using the PRS signals. The V2X entity or a different V2X entity may also transmit PRS signals that are received by the UE and used along with the PRS signal from the neighbor base stations to perform position determination.

    Abstract: A method of locating a target device includes: producing, at a query device, a request for a location of a target device, the query device including a first radio, of a first type, configured to communicate wirelessly using a first communication protocol, the target lacking a radio of the first type but including a second radio, of a second type, configured to communicate wirelessly using a second communication protocol, the second communication protocol being incompatible with the first communication protocol; and transmitting the request wirelessly, from the query device to a first intermediate device, using the first radio.

    Abstract: Measurements from a plurality of Access Points (APs) may be used to determine that at least one AP in the plurality is mobile. Measurements from APs determined to be mobile may be excluded when determining a User Equipment (UE) location. Disclosed embodiments also pertain to AP mobility characterization. AP mobility may be determined based on range rate measurements such as Round Trip Time measurements between the AP and UE; or a Doppler frequency shift relative to a nominal frequency used by the AP for transmissions. Based on range rate measurements, a probability of mobility may be assigned to APs. Information pertaining to APs that are determined to be stationary or associated with a low probability of mobility may be reported to a location server. Information pertaining to APs determined to be mobile or associated with a higher probability of mobility may not be reported to a location server.
