Abstract
Embodiments of the present application relate to methods and apparatuses for a dual active protocol stack (DAPS) failure recovery mechanism and a mobility robustness optimization (MRO) mechanism for conditional handover (CHO) and DAPS procedures. According to an embodiment of the present application, a method can include: receiving CHO configuration information, wherein the CHO configuration information is associated with a CHO candidate cell, wherein the CHO configuration information includes a RRC reconfiguration message and a set of one or more execution conditions; in response to meeting one or more execution conditions associated with the CHO candidate cell, performing 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, transmitting time related assistant information to a serving cell, wherein the serving cell is one of the source cell and the CHO candidate cell. In addition, a recovery procedure and a MRO mechanism associated with a DAPS handover procedure are also studied.
