Abstract

Provided are a method and an apparatus for aggregating the WLAN with an E-UTRAN carrier at a radio access network (RAN) level and using the same to transmit and receive LTE-WLAN aggregation data. A method of a terminal for receiving data by aggregating a WLAN carrier may include transmitting WLAN MAC address information or IP address information which are configured in the terminal, receiving configuration information to configure a specific bearer through the WLAN carrier, receiving the data through the base station and the WLAN carrier, respectively, and transferring the specific bearer data received through the WLAN carrier to a PDCP entity of the specific bearer within the terminal.

Claims

1-20. -20. (canceled)

21. 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.

22. The method of claim 21, wherein the first aggregation entity is configured to correspond to a second aggregation entity which is configured in the base station.

23. The method of claim 21, wherein the first aggregation entity is configured in a lower layer of the PDCP entity within the UE.

24. The method of claim 21, wherein the data received through the WLAN carrier includes identification information for transferring, by the first aggregation entity, the data received through the WLAN carrier to the PDCP entity of the specific bearer within the UE.

25. The method of claim 24, wherein the identification information includes one of logical channel identifier information, bearer identification information, and wireless bearer index information.

26. 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.

27. The method of claim 26, wherein the second aggregation entity is configured to correspond to the first aggregation entity which is configured in the UE.

28. The method of claim 26, wherein the second aggregation entity is configured in a lower layer of a packet data convergence protocol (PDCP) entity within the base station.

29. The method of claim 26, wherein the identification information includes information for the UE to transfer data received through the WLAN carrier to a PDCP entity of a specific bearer within the UE.

30. The method of claim 26, wherein the identification information includes one of logical channel identifier information, bearer identification information, and wireless bearer index information.

31. 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.

32. The UE of claim 31, wherein the first aggregation entity is configured to correspond to a second aggregation entity which is configured in the base station.

33. The UE of claim 31, wherein the first aggregation entity is configured in a lower layer of a packet data convergence protocol (PDCP) entity within the UE.

34. The UE of claim 31, wherein the data received through the WLAN carrier includes identification information with data received through the WLAN carrier and transferred by the first aggregation entity to the PDCP entity of the specific bearer within the UE.

35. The UE of claim 34, wherein the identification information includes one of logical channel identifier information, bearer identification information, and wireless bearer index information.
