  • Publication number: 20240118370
    Abstract: An anchor UE may move or have a low transmission power and impact the accuracy of positioning estimates of a target UE based on measurements of the PRSs associated with the anchor UE. One or more candidate anchor UEs may be selected or excluded from being used for positioning based on one or more of a measurement quality metric of a position measurement of a candidate anchor UE, a mobility status of the candidate anchor UE, or a GDOP associated with the candidate anchor UE. A mobility status of the candidate anchor UE may be derived from reported positions of the candidate anchor UE or obtained from the candidate anchor UE. A UE selected as an anchor UE is used for positioning of a target UE, and a UE downselected from being an anchor UE is excluded from use for positioning of the target UE.

  • Publication number: 20240114480
    Abstract: A determination of a position of a target mobile device in a wireless communication network employing time-division duplexing (TDD) can use a wireless reference signal from another mobile device with a known position. The other mobile device can be configured to transmit the wireless reference signal using cross-link interference (CLI), where the target mobile device receives the signal during a period in which the target mobile device is configured to receive downlink (DL) communication. The target mobile device then transmits another wireless reference signal, which is received by a base station, which also receives the wireless reference signal from the other mobile device. The timing of these various signals received at the target mobile device and base station can be used to determine the location of the mobile device.

  • Publication number: 20240104202
    Abstract: Man-in-the-middle attacks on reference signals used for positioning a mobile device in a wireless network can be detected through time and/or angle consistency checks. Time consistency checks may be based on a consistency of peak location and/or power delay profile across multiple reference signals and/or across different signal types, for example. Angle consistency checks may be based on a consistency of an angle at which a reference signal is received across multiple reference signals and/or in comparison with an expected angle, for example. Embodiments may further include reporting detected attacks.
