Apparatus and method for providing multiple connections using different radio access technology in wireless communication system

A method for operating an access node in a wireless communication system, the method comprising:

• receiving, from a base station supporting a first radio access technology (RAT), a first message for requesting to allocate a resource of a second RAT to a terminal;
• and
• performing an association and an authentication with the terminal;
• receiving, from the base station, a packet data unit (PDU) of the first RAT;
• and
• transmitting, to the terminal, data including the PDU and information indicating that the data includes the PDU of the first RAT,
• wherein the base station supports the first RAT,
• wherein the access node supports the second RAT that is different from the first RAT, and
• wherein the first RAT and the second RAT are used for an aggregation operation for the terminal.

A base station in a wireless communication system, the base station comprising:

• at least one transceiver;
• and
• at least one processor coupled to the at least one transceiver and configured to:
• receive, from a terminal, capability information on an aggregation operation using a first radio access technology (RAT) and a second RAT;
• transmit, to the terminal, a first message including a service set identification (SSID) of an access node and information on an authentication for the access node;
• transmit, to the access node, a second message for requesting to allocate a resource of the second RAT;
• and
• transmit, to the terminal, first data by using the first RAT and transmit, to the terminal, second data via the access node by using the second RAT, after the terminal performs an association and the authentication with the access node based on the SSID and the information on the authentication,
• wherein the base station supports the first RAT,
• wherein the access node supports the second RAT that is different from the first RAT,
• wherein the capability information includes a media access control (MAC) address of the terminal, and
• wherein the second data includes a packet data unit (PDU) of the first RAT.
