The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A method for managing a link in a wireless communication may comprise the steps of: collecting and storing RLF report content for an RLF report when DC-related MCG failure is detected; transmitting an MCG failure information message related to the MCG failure to a first base station; when a response message related to the MCG failure is not received within a predetermined time period after the MCG failure information message is transmitted, adding, to the stored RLF report content, an indicator indicating that fast MCG link recovery has not been successfully completed; and transmitting an RLF report including the stored RLF report content to a second base station during a wireless link re-establishment procedure after the MCG failure.
