摘要： A method for positioning in a wireless communication system is described. The method comprises receiving, by a second node (102), a capability-request signal from a first node (106). The second node (102) transmits a capability-response signal to the first node (106). The second node (102) transmits an assistance information to the first node (106). The second node (102) transmits the configuration of the at least one reference signal to a third node (104). The second node (102) receives a reference signal from the third node (104). The second node (102) performs measurement on the reference signal and transmits report comprising the measurement to the first node (106), where the first node (106) estimates a position of the third node (104) based on the report received from the second node (102).

摘要： 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.

摘要： A method for localizing a user device using a Time-of-Flight (ToF) antenna array disposed on a vehicle, the method includes determining via a ToF localization controller, that a user device is positioned at a front region of a vehicle, calculating a distance to the user device from a combination of two ToF antennae of the ToF antenna array, and performing a 2-dimensional (2D) trilateration calculation. The method further includes evaluating a confidence metric value, determining a position of the user device based on the confidence metric value, and generating an unlock signal that unlocks a vehicle door.

摘要： A method includes obtaining signal information based on wireless signals received from an external electronic device via a first antenna pair and a second antenna pair. The first and second antenna pairs are aligned along different axes. The signal information includes channel information, range information, a first angle of arrival (AoA) based on the first antenna pair, and a second AoA based on the second antenna pair. The method also includes generating an initial prediction of a presence of the external electronic device relative to a field of view (FoV) of the electronic device. The method further includes performing a smoothing operation on the range information and the first and second AoA, the smoothing operation generating a predicted location of the external electronic device relative to the FoV of the electronic device. Additionally, the method includes generating, based on the smoothing operation, confidence values associated with the predicted location.

摘要： Various example embodiments are described in which a network node transmits to a user device preconfiguration information for a plurality of on-demand positioning signal (ODPS) preconfigurations. An ODPS preconfiguration may be selected and communicated. The transmitted ODPS preconfiguration may be a request for transmission, or a notice of transmission, of the selected ODPS. An ODPS, which is associated with or based on the selected ODPS preconfiguration, may be transmitted. The ODPS may include any positioning signal (e.g., any signal that may be used for positioning) that may be transmitted upon request or as needed, and, e.g., may include downlink on-demand positioning reference signals (ODPRS), uplink on-demand sounding reference signals (ODSRS), or other positioning or reference signal.
