1. A method for an operation related to a Radio Link Failure (RLF) in a wireless communication system performed by a user equipment (UE), comprising:monitoring a radio link state of a serving base station (BS);
detecting a physical layer problem;
transmitting a specific random access preamble related to the RLF to one or more neighboring BSs through a specific Physical Random Access Channel (PRACH) resource;
receiving a random access response from the one or more neighboring BSs;
determining a neighboring BS to which an additional RRC connection is to be configured based on the received random access response; and
configuring an RRC connection with the determined neighboring BS,
wherein the specific PRACH resource is a common PRACH resource that is separately configured to transmit the specific random access preamble.
