Classification: CPC H | IPC H

Claim 8:
9. A user equipment (UE) in a communication system, the UE comprising:
a transceiver; and
a controller operably coupled to the transceiver, the controller configured to:
receive, from a base station associated with new radio-radio access (NR) via the transceiver, a command message for inter-radio access technology (RAT) handover from the NR to a target RAT, wherein the command message includes information on a type of the target RAT,
perform a procedure associated with the inter-RAT handover based on the command message,
in case that a failure condition for the inter-RAT handover is satisfied, identify that the inter-RAT handover fails, and
in case that the type of the target RAT is set to evolved universal terrestrial radio access (EUTRA) and the UE supports a radio link failure report for inter-RAT mobility robustness optimization (MRO) EUTRA, store handover failure information in a variable for the radio link failure report based on an identification that the inter-RAT handover fails.
