1. A communication device for handling a recovery of a radio resource control (RRC) connection of a non-terrestrial network (NTN), comprising:
at least one storage device; and
at least one processing circuit, coupled to the at least one storage device,
wherein the at least one storage device stores instructions, and the at least one processing circuit is configured to execute the instructions of:
establishing an RRC connection with a first cell of the NTN;
receiving a collaborator cell configuration message from the first cell,
wherein the collaborator cell configuration message comprises at least one collaborator cell configuration associated with at least one cell of the NTN;
initiating a RRC connection recovery procedure, after receiving the collaborator cell configuration message;
selecting a second cell for the RRC connection recovery procedure, when the communication device initiates the RRC connection recovery procedure; and
performing a RRC connection re-establishment procedure with the second cell according to system information associated with the second cell, when the second cell is not associated with the at least one collaborator cell configuration associated with the at least one cell of the NTN and the communication device is not configured with a valid handover configuration associated with the second cell.
