Abstract

Provided are a method and apparatus for processing user plane data by a terminal. The method may include: receiving additional configuration information for additionally configuring a WLAN carrier using an unlicensed frequency band; receiving downlink user plane data through a base station carrier using the WLAN carrier or a licensed frequency band according to the additional configuration information; and transmitting included uplink user plane data through the WLAN carrier or the base station carrier according to the additional configuration information.

Claims

1-20. -20. (canceled)

21. A method for processing data by a terminal, the method comprising:

configuring a user plane entity for receiving data from a base station through a wireless local area network (WLAN) carrier;

receiving user plane data from the base station through the user plane entity; and

transmitting control information indicating successful or unsuccessful reception of the user plane data through the WLAN carrier to the base station through an interface between the terminal and the base station.

22. The method according to claim 21, wherein the user plane entity is configured in a lower layer of a packet data convergence protocol (PDCP) layer.

23. The method according to claim 21, further comprising receiving radio bearer configuration information or PDCP configuration information including parameters for transmission of the control information through an upper layer signaling,

wherein the parameters for the transmission of the control information include at least one piece of information instructing the transmission of the control information, information on a transmission method of the control information, or information on a transmission period thereof.

24. The method according to claim 21, wherein the control information is provided from at least one of the user plane entity and a PDCP entity.

25. The method according to claim 21, wherein the transmission of the control information is triggered based on at least one of polling of the base station, a period and a timer, which is set by the base station.

26. A method for processing data by a base station, the method comprising:

configuring a user plane entity for transmitting data to a terminal through a wireless local area network (WLAN) carrier;

transmitting user plane data to the terminal through the user plane entity; and

receiving control information indicating successful or unsuccessful reception of the user plane data through the WLAN carrier from the terminal through an interface between the terminal and the base station.

27. The method according to claim 26, wherein the user plane entity is configured in a lower layer of a packet data convergence protocol (PDCP) layer.

28. The method according to claim 26, further comprising transmitting radio bearer configuration information or PDCP configuration information including parameters for transmission of the control information of the terminal through an upper layer signaling,

wherein the parameters for the control information transmission include at least one piece of information instructing the transmission of the control information, information on a transmission method of the control information, and information on a transmission period thereof.

29. The method according to claim 26, wherein the control information is provided from at least one of the user plane entity and a PDCP entity of the terminal.

30. The method according to claim 26, wherein the transmission of the control information is triggered based on at least one of polling of the base station, a period, and a timer, which is set by the base station.

31. A terminal for processing data, the terminal comprising:

a controller configured to configure a user plane entity for receiving data from a base station through a wireless local area network (WLAN) carrier;

a receiving unit configured to receive user plane data from the base station through the user plane entity; and

a transmitting unit configured to transmit control information indicating successful or unsuccessful reception of the user plane data through the WLAN carrier to the base station through an interface between the terminal and the base station.

32. The terminal according to claim 31, wherein the user plane entity is configured in a lower layer of a packet data convergence protocol (PDCP) layer.

33. The terminal according to claim 31, wherein the receiving unit is configured to receive radio bearer configuration information or PDCP configuration information including parameters for transmission of the control information through an upper layer signaling,

wherein the parameters for the transmission of the control information include at least one piece of information instructing the transmission of the control information, information on a transmission method of the control information, and information on a transmission period thereof.

34. The terminal according to claim 31, wherein the control information is provided from at least one of the user plane entity and a PDCP entity.

35. The terminal according to claim 31, wherein the transmission of the control information is triggered based on at least one of polling of the base station, a period, and a timer, which is set by the base station.
