Claims

1-22. -22. (canceled)

23. A method of operating a terminal in a wireless communication system, comprising:

receiving a control message from a first base station which controls a first cell group, the control message including configuration information for configuring a second cell group which is controlled by a second base station;

identifying a bearer type associated with the second cell group based on the configuration information; and

if the bearer type is a first bearer type, configuring uplink transmission on one of the first and second cell group based on the configuration information.

24. The method of claim 23, further comprising configuring uplink transmission on the second cell group if the bearer type is a second bearer type.

25. The method of claim 23, further comprising;

if the bearer type is the first bearer type, indicating data available for uplink transmission to a MAC entity configured for the first cell group or a MAC entity configured for the second cell group based on the configuration information.

26. A method of operating a base station configured to control a first cell group in a wireless communication system, comprising:

determining, with another base station, to configure a second cell group which is controlled by the other base station;

transmitting, to a terminal, a control message which includes configuration information comprising information for configuring the second cell group, information for indicating a bearer type associated with the second cell group and information for indicating whether the second cell group is used for uplink transmission.

27. The method of claim 26, further comprising omitting to transmit and receive data on the first cell group if the bearer type is a second bearer type.

28. The method of claim 26, wherein, if the bearer type is the first bearer type, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the first cell group or a MAC entity configured for the second cell group based on the uplink information.

29. A method of operating a base station configured to control a second cell group in a wireless communication system, comprising:

determining, with another base station, to configure the second cell group; and

if a bearer type associated with the second cell group is a first bearer type and the second cell group is selected to uplink transmission, receiving data from a terminal on the second cell group,

wherein a control message including configuration information comprising information for configuring the second cell group, information for indicating the bearer type associated with the second cell group and information for indicating whether the second cell group is used for uplink transmission is transmitted from the other base station to the terminal.

30. The method of claim 29, further comprising transmitting and receiving data on the second cell group if the bearer type is a second bearer type.

31. The method of claim 29, wherein, if the bearer type is the first bearer type and the first cell group is selected to uplink transmission based on the control message, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the first cell group, and

if the bearer type is the first bearer type and the second cell group is selected to uplink transmission based on the control message, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the second cell group.

32. A terminal comprising:

a transceiver configured to transmit and receive signals with a first and second base station; and

a control unit configured to;

receive a control message from the first base station which controls a first cell group, the control message including configuration information for configuring a second cell group which is controlled by the second base station;

identify a bearer type associated with the second cell group based on the configuration information; and

if the bearer type is a first bearer type, configure uplink transmission on one of the first and second cell group based on the configuration information.

33. The terminal of claim 32, wherein the control unit is further configured to configure uplink transmission on the second cell group if the bearer type is a second bearer type.

34. The terminal of claim 32, wherein the control unit is further configured to indicate data available for uplink transmission to a MAC entity configured for the first cell group or a MAC entity configured for the second cell group based on the configuration information if the bearer type is the first bearer type.

35. A base station configured to control a first cell group, the base station comprising:

a transceiver configured to transmit and receive signals with a terminal and another base station; and

a control unit configured to;

determine, with the other base station, whether to configure a second cell group which is controlled by the other base station;

transmit, to the terminal, a control message which includes configuration information comprising information for configuring the second cell group, information for indicating a bearer type associated with the second cell group, and information for indicating whether the second cell group is used for uplink transmission.

36. The base station of claim 35, wherein the control unit is further configured to omit to transmit and receive data on the first cell group if the bearer type is a second bearer type.

37. The base station of claim 35, wherein, if the bearer type is the first bearer type, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the first cell group or a MAC entity configured for the second cell group based on the uplink information.

38. A base station configured to control a second cell group, the base station comprising:

a transceiver configured to transmit and receive signals with a terminal and another base station; and

a control unit is configured to;

determine, with the other base station, whether to configure the second cell group; and

if a bearer type associated with the second cell group is a first bearer type and the second cell group is selected to uplink transmission, receive data from the terminal on the second cell group,

wherein a control message including configuration information comprising information for configuring the second cell group, information for indicating the bearer type associated with the second cell group, and information for indicating whether the second cell group is used for uplink transmission is transmitted from the other base station to the terminal.

39. The base station of claim 38, wherein the control unit is further configured to transmit and receive data on the second cell group if the bearer type is a second bearer type.

40. The base station of claim 38, wherein, if the bearer type is the first bearer type and the first cell group is selected to uplink transmission based on the control message, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the first cell group, and

if the bearer type is the first bearer type and the second cell group is selected to uplink transmission based on the control message, data available for uplink transmission is indicated, by the terminal, to a MAC entity configured for the second cell group.
