Method and apparatus for radio link failure reporting in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• performing a random access procedure with a terminal;
• and
• receiving, from the terminal, a report of a radio link failure,
• wherein the radio link failure is detected by a radio resource control (RRC) entity, based on a random access problem indication from a medium access control (MAC) entity for the random access procedure, and
• wherein radio link failure cause information is generated for the report of the radio link failure, based on an identification on whether the random access procedure was initiated for beam failure recovery or not.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• identify, by a radio resource control (RRC) entity, that a radio link failure is detected based on a random access problem indication obtained from a medium access control (MAC) entity for a random access procedure,
• identify, by the RRC entity, whether the random access procedure was initiated for beam failure recovery,
• generate, by the RRC entity, radio link failure cause information based on the identification, for a report of the radio link failure, and
• transmit, to a base station, the report of the radio link failure.
