Abstract
A method and apparatus for performing a random access (RA) procedure in a wireless communication system is provided. A user equipment (UE) establishes connection with a first node and a second node, and transmits an RA preamble to the second node. If a number of RA preamble transmissions reaches a maximum number, the UE stops uplink (UL) transmission of all cells in a group to which the second node belongs, and transmits an indication indicating that transmission of the RA preamble has failed to the first node.
