  • Publication number: 20240163738
    Abstract: Apparatus and method are provided for a user equipment (UE) to perform measurement operations for a handover procedure including target NR Primary Secondary Cell (PSCell) change or addition. The measurements of a target PSCell are performed in accordance with a synchronization signal/physical broadcast channel (SS/PBCH) block measurement time configuration (SMTC) included in a measurement object received from a base station (BS). A source primary cell (PCell) is used for reference timing of the SMTC if the measurement object is configured by the source PCell on same frequency and subcarrier spacing of the target PSCell. A source PSCell is used for reference timing of the SMTC if the measurement object is configured by the source PSCell on same frequency and subcarrier spacing of the target PSCell.

  • Publication number: 20240155398
    Abstract: Systems and methods for analyzing a validity of an early measurement report (EMR) measurement result are described herein. A base station may configure a threshold value for EMR result validity and receive, from a user equipment (UE), a first measurement value corresponding to a first time at or before expiration of a timer associated with idle mode or inactive mode measurements. The base station receives, from the UE, a second measurement value corresponding to a second time when a radio resource control (RRC) connection setup or resume procedure starts. The base station then determines, based on a comparison of the threshold value to a difference between the first measurement value and the second measurement value, whether the EMR result is valid.
