Methods and apparatuses for a DAPS failure recovery mechanism and a MRO mechanism for CHO and DAPS procedures

A user equipment (UE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• receive first conditional handover (CHO) configuration information that is associated with a CHO candidate cell, the first CHO configuration information including a first radio resource control (RRC) reconfiguration message and a first set of one or more execution conditions;
• in response to meeting one or more execution conditions associated with the CHO candidate cell, perform a CHO procedure from a source cell to the CHO candidate cell;
• and
• in response to successfully accessing the CHO candidate cell or in response to an occurrence of a failure during the CHO procedure, transmit time related assistant information to a serving cell that is one of the source cell or the CHO candidate cell, wherein the time related assistant information includes a time duration between a time instance of receiving a latest CHO configuration information and a time instance of starting to perform the CHO procedure.

• in response to successfully completing the CHO procedure, transmit, to the CHO candidate cell, an indication of an available state of the time related assistant information;
• receive, from the CHO candidate cell, a UE information request message after successfully completing the CHO procedure;
• and
• transmit a UE information response message to the CHO candidate cell, wherein the UE information response message includes the time related assistant information.
