Method and apparatus for transmitting data by using wireless lan carrier

A method for receiving, by a user equipment (UE), data by aggregating a wireless local area network (WLAN) carrier, comprising:

• configuring a first aggregation entity within a UE to process data received through a WLAN carrier;
• receiving data through at least one of a base station and the WLAN carrier;
• and
• transferring, by the first aggregation entity, data of a specific bearer to a data packet convergence protocol (PDCP) entity of a specific bearer within the UE, wherein, the data of the specific bearer is received through the WLAN carrier.

A method for transmitting data using a wireless local area network (WLAN) carrier by a base station, comprising:

• configuring a second aggregation entity within a base station to process data transmitted through a WLAN carrier;
• receiving, from a packet data convergence protocol (PDCP) entity, data transmitted through the WLAN carrier, and adding identification information thereto, by the second aggregation entity;
• and
• transmitting, by the second aggregation entity, the data transmitted through the WLAN carrier to a first aggregation entity using the WLAN carrier, wherein the first aggregation is configured within the UE.

A user equipment (UE) for receiving data by aggregating a wireless local area network (WLAN) carrier, comprising:

• a controller configured to configure a first aggregation entity within a UE to process data received through a WLAN carrier;
• and
• a receiver configured to receive data through at least one of a base station and the WLAN carrier,
• wherein the controller controls the first aggregation entity to transfer data of a specific bearer, received through the WLAN carrier, to a packet data convergence protocol (PDCP) entity of a specific bearer within the UE.
