REFERENCE SELECTION FOR HANDOVER WITH PSCELL CHANGE OR ADDITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17777155 titled 'REFERENCE SELECTION FOR HANDOVER WITH PSCELL CHANGE OR ADDITION

Simplified Explanation

The patent application describes an apparatus and method for a user equipment (UE) to perform measurement operations for a handover procedure involving a target NR Primary Secondary Cell (PSCell) change or addition. The measurements of the target PSCell are conducted based on a synchronization signal/physical broadcast channel (SS/PBCH) block measurement time configuration (SMTC) received from a base station (BS). The source primary cell (PCell) or source PSCell is used for reference timing of the SMTC depending on the configuration by the source cell on the same frequency and subcarrier spacing of the target PSCell.

• Target NR PSCell measurement operations for handover procedure
• Utilization of SS/PBCH block measurement time configuration (SMTC) for measurements
• Reference timing from source PCell or source PSCell based on configuration
• Synchronization signal/physical broadcast channel (SS/PBCH) block utilization

Original Abstract Submitted

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.
