Methods and apparatuses for handling a conditional handover (cho) execution condition in a non terrestrial network (ntn) environment

An apparatus, comprising:

• at least one non-transitory computer-readable medium having stored thereon computer-executable instructions;
• at least one receiving circuitry;
• at least one transmitting circuitry;
• and
• at least one processor coupled to the at least one non-transitory computer-readable medium, the at least one receiving circuitry and the at least one transmitting circuitry,
• wherein the computer-executable instructions cause the at least one processor to implement a method, the method comprising:
• receiving a radio resource control (RRC) reconfiguration message, wherein the RRC reconfiguration message includes conditional handover (CHO) configuration information associated with one or more target candidate cells and a set of parameters of CHO execution conditions associated with the one or more target candidate cells;
• evaluating one or more CHO execution conditions associated with each of the one or more target candidate cells;
• determining whether a CHO execution condition associated with a target candidate cell is satisfied;
• and
• in response to satisfying the CHO execution condition, performing a CHO procedure from a source cell to the target candidate cell.
