Method of utilizing a relay node in wireless communication system

A method of establishing a Radio Resource Control (RRC) connection in a wireless communication system, the method comprising:

• transmitting, from a mobile terminal, a RRC connection request message to a base station;
• receiving, by the mobile terminal, a RRC connection setup message from the base station in response to the transmitted RRC connection request message;
• and
• transmitting, from the mobile terminal, a RRC connection setup complete message to the base station after the reception of the RRC connection setup message by the mobile terminal,
• wherein the steps of transmitting the RRC connection request message, receiving the RRC connection setup message, and the transmitting the RRC connection setup complete message are performed during a RRC connection establishment, and
• wherein the RRC connection setup complete message indicates that the RRC connection is for the RN only when the RRC connection setup complete message includes information indicating that the RRC connection is for the RN.

An apparatus for establishing a Radio Resource Control (RRC) connection in a wireless communication system, the apparatus comprising:

• a memory;
• a transceiver;
• and
• a processor, the processor configured to:
• transmit, from a mobile terminal, a RRC connection request message to a base station;
• receive a RRC connection setup message from the base station in response to the transmitted RRC connection request message;
• and
• transmit a RRC connection setup complete message to the base station after the reception of the RRC connection setup message by the mobile terminal,
• wherein the RRC connection request message is transmitted, the RRC connection setup message is received, and the RRC connection setup complete message is transmitted during a RRC connection establishment, and
• wherein the RRC connection setup complete message indicates that the RRC connection is for the RN only when the RRC connection setup complete message includes information indicating that the RRC connection is for the RN.
