  • Patent number: 11609299
    Abstract: The positions of multiple user equipments (UEs) are jointly determined by a location server using positioning measurements from a comment set of positioning reference signals (PRS), which may include downlink (DL) PRS, uplink (UL) PRS, sidelink (SL) PRS, or a combination thereof. The common set of PRS may be selected by the location server, e.g., based on a rough estimate of position of the UEs determined by the location server, a recommendation from the UEs, or a position report from the UEs. Once selected by the location server, an indication of the common set of PRS is sent to the UEs. The common set of PRS, alternatively, may be selected by one or more UEs, e.g., by a controlling UE or consensus, and one or more UEs provide an indication of the common set of PRS to the location server.

  • Patent number: 11595938
    Abstract: A user equipment (UE) receives assistance data for positioning that includes relative position information for anchor points, such as base stations and/or sidelink UEs. The relative position information may include, for example, distances or angles between anchor points. The UE performs positioning measurements for reference signals received from the anchor points. The UE performs outlier rejection of the positioning measurements using the relative position information. Positioning measurements selected by the UE using the relative position information are provided to a location server. The location server may perform UE-assisted positioning using the selected position measurements and the actual locations of the anchor points. Accordingly, the outlier rejection of the position measurements may be off loaded from the location server to the UE while maintaining confidentiality of the actual locations of the anchor points.
