Abstract: A method and apparatus for providing beam related information for connection failure detection in a wireless communication system is provided. In case that radio link failure (RLF) occurs due to too late handover, too early handover or handover to wrong cell, a gNB in which a user equipment (UE) attempts to re-establish or establish a radio resource control (RRC) connection provides RLF related information with beam related information to a gNB at which RLF happened.

Abstract: Provided are a method and a device for receiving information indicating the type of a signaling radio bearer (SRB) in a wireless communication system. A user equipment (UE): receives a first radio resource control (RRC) message including information indicating the type of SRB on which a second RRC message, which is a message corresponding to the first RRC message, is to be transmitted; and transmits the second RRC message via the type of SRB indicated by the information indicating the type of SRB. Accordingly, the type of bearer on which a first message is received and the type of bearer on which a second message is transmitted in a single RRC procedure may be identical or mutually different.
