Apparatus and method for supporting unicast transmission between user equipments in wireless communication system

A method performed by a base station, the method comprising:

• receiving, from a first terminal, a first message including a destination identity, transmission type information, radio link control (RLC) mode information, and quality of service QoS) information;
• determining an RLC mode, based on the first message;
• and
• transmitting, to the first terminal, a second message including sidelink RLC configuration information associated with the RLC mode,
• wherein the sidelink RLC configuration information is configured by a second terminal.

A first terminal in a wireless communication system, the first terminal comprising:

• a transceiver unit;
• and
• a control unit connected to the transceiver unit, the control unit configured to:
• transmit, to a base station, a first message including a destination identity, transmission type information, radio link control (RLC) mode information, and quality of service (QoS) information,
• receive, from the base station, a second message including sidelink RLC configuration information associated with an RLC mode based on the first message, and
• transmit, to a second terminal, a third message comprising the sidelink RLC configuration information based on the second message,
• wherein the sidelink RLC configuration information is configured by the second terminal based on the third message.
