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.

1-15. (canceled)
A method for performing, by a user equipment (UE), a random access (RA) procedure in a wireless communication system, the method comprising:
- establishing connection with a first node and a second node;
- transmitting an RA preamble to the second node;
- and
- if a number of RA preamble transmissions reaches a number associated with maximum preamble transmissions, transmitting an indication indicating an RA problem to the first node.
A user equipment (UE) comprising:
- a memory;
- a radio frequency (RF) unit;
- and
- a processor coupled to the memory and the RF unit, and configured to:
- establish connection with a first node and a second node;
- control the RF unit to transmit a random access (RA) preamble to the second node;
- and
- if a number of RA preamble transmissions reaches a number associated with maximum preamble transmissions, control the RF unit to transmit an indication indicating an RA problem to the first node.
