Abstract

Provided is a method of transmitting control information of a base station in a mobile communication system includes obtaining scheduling information from a terminal; and transmitting at least two control channels through one down link carrier, wherein each control channel corresponds to a different uplink carrier.

Claims

1. A method for transmitting control information of a base station in a mobile communication system, the method comprising:

obtaining scheduling information from a terminal; and

transmitting at least two control channels through one down link carrier,

wherein each control channel corresponds to a different uplink carrier.

2. The method of claim 1, wherein the each control channel comprises identification information for the uplink carrier.

3. The method of claim 1, further comprising:

transmitting control information including information indicating whether a plurality of uplink carriers are used to the terminal.

4. The method of claim 1, wherein the control channel is related with scheduling grant or retransmission information.

5. A method for receiving control information of a base station in a mobile communication system, the method comprising:

transmitting scheduling information to a base station; and

receiving at least two control channels from the base station through one down link carrier,

wherein each control channel corresponds to a different uplink carrier.

6. The method of claim 5, wherein the each control channel comprises identification information for the uplink carrier.

7. The method of claim 5, further comprising:

receiving control information including information indicating whether a plurality of uplink carriers are used from the terminal.

8. The method of claim 5, wherein the control channel is related with scheduling grant or retransmission information.

9. A base station for transmitting control information in a mobile communication system, the base station comprising:

a scheduler that performs scheduling by using scheduling information received from a terminal; and

a control information processing module that controls to transmit at least two control channels through one down link carrier,

wherein each control channel corresponds to a different uplink carrier.

10. The method of claim 9, wherein the each control channel comprises identification information for the uplink carrier.

11. The method of claim 9, further comprising:

a controller that decides a use of a plurality of uplink carriers according to the scheduling result; and

a control channel transmission resource processing module that generates control information including information indicating whether the decided plurality of uplink carriers are used and transmits the control information.

12. The method of claim 9, wherein the control channel is related with scheduling grant or retransmission information.

13. A terminal for receiving control information in a mobile communication system, the terminal comprising:

a controller that controls to transmit scheduling information to a base station; and

a control information reception module that receives at least two control channels through one down link carrier from the base station,

wherein each control channel corresponds to a different uplink carrier.

14. The method of claim 13, wherein the each control channel comprises identification information for the uplink carrier.

15. The method of claim 13, further comprising:

a control channel transmission resource reception module that receives control information including information indicating whether a plurality of uplink carriers are used from the base station.

16. The method of claim 15, wherein the control channel is related with scheduling grant or retransmission information.
