Systems and Methods for User Equipment History Information Update for Conditional Handover and Conditional Primary Secondary Cell Group Cell Change

A method by a target network node associated with a Conditional Handover (CHO) or Conditional Primary Secondary Cell Group Cell (PSCell) change of a user equipment (UE), the method comprising:

• receiving, from a source network node, a first message requesting the CHO or Conditional PSCell change of the UE, the first message comprising user equipment history information (UHI);
• receiving, from the UE, a second message indicating a completion of applying a Radio Resource Control (RRC) reconfiguration;
• and
• updating the UHI based on an amount of time between receiving the first message comprising the UHI and receiving the second message indicating the completion of applying the RRC reconfiguration.

A target network node associated with a Conditional Handover (CHO) or Conditional Primary Secondary Cell Group Cell (PSCell) change of a user equipment (UE), the target network node comprising processing circuitry configured to:

• receive, from a source network node, a first message requesting the CHO or Conditional PSCell change of the UE, the first message comprising user equipment history information (UHI);
• receive, from the UE, a second message indicating a completion of applying a Radio Resource Control (RRC) reconfiguration;
• and
• update the UHI based on an amount of time between receiving the first message comprising the UHI and receiving the second message indicating the completion of the applying the RRC reconfiguration.
