  • Publication number: 20230318725
    Abstract: Methods and apparatus for predicting wireless measurements based on virtual access points is described. In some embodiments, a location of a user equipment (UE) may be obtained, and given the location of the UE, an output may be generated using a machine learning model, the output including one or more predicted wireless measurements. The output may be indicative of a wireless channel in a multipath environment. In some variants, the machine learning model may have been trained by obtaining a training dataset comprising multipath components data and ground truth locations of a wireless device, and performing an optimization with respect to the multipath components data and the ground truth locations. In some implementations, a training output comprising a predicted multipath component may be produced during the training, and the optimization may include an iterative minimization of an error between at least the predicted multipath component and a labeled multipath component.

  • Publication number: 20230288524
    Abstract: A user equipment (UE) may define the classes of a plurality of path delay detection algorithms that the UE may use to identify line-of-sight positioning signals and reject non-line-of-sight positioning signals. The UE may receive a capabilities request from a location server and transmit, to the location server, a capability report indicating the classes of the plurality of path delay detection algorithms supported by the UE. The UE receives a location information request from a location server, and selects a path delay detection algorithm, which is used to perform measurements of one or more positioning signals received by the UE. The UE provides an indication of the selected path delay detection algorithm along with the positioning measurements to the location server. The location server determines or verifies a location of the UE based on the path delay detection algorithm selected by the UE and the positioning measurements.
