  • Publication number: 20240381141
    Abstract: Aspects are directed to multiple carrier phase measurements associated with a positioning frequency layer (e.g., instead of measuring and/or reporting a single carrier phase measurement per positioning frequency layer at the central frequency of the positioning frequency layer). Other aspects are directed to reduced positioning frequency layer bandwidth for reference signal for positioning measurements (e.g., for reduced capability or “RedCap” user equipments). Other aspects are directed to differential carrier phase measurement reporting.
