Abstract

A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.

Claims

1. A method for a mobile station to communicate control information in a wireless communication system, the method comprising:

receiving scheduling information via plural control resource units; and

transmitting or receiving acknowledgement information for data indicated by the scheduling information,

wherein a resource index for the acknowledgement information is determined based on a lowest one of plural indexes indicating the plural control resource units.

2. The method of claim 1, wherein the resource index for the acknowledgement information is determined further based on an offset.

3. The method of claim 1, further comprising:

receiving the data indicated by the scheduling information.

4. The method of claim 1, further comprising:

transmitting the data indicated by the scheduling information.

5. The method of claim 1, wherein the plural control resource units includes control channel elements (CCEs).

6. A mobile station for use in a wireless communication system, the mobile station comprising:

a radio frequency (RF) unit;

a processor,

wherein the processor is configured to control the RF to;

receive scheduling information via plural control resource units, and

transmit or receive acknowledgement information for data indicated by the scheduling information,

wherein a resource index for the acknowledgement information is determined based on a lowest one of plural indexes indicating the plural control resource units.

7. The mobile station of claim 6, wherein the resource index for the acknowledgement information is determined further based on an offset.

8. The mobile station of claim 6, wherein the processor is further configured to control the RF unit to receive the data indicated by the scheduling information.

9. The mobile station of claim 6, wherein the processor is further configured to control the RF unit to transmit the data indicated by the scheduling information.

10. The mobile station of claim 6, wherein the plural control resource units includes control channel elements (CCEs).

11. A base station for use in a wireless communication system, the base station comprising:

a radio frequency (RF) unit;

a processor,

wherein the processor is configured to control the RF to;

transmit scheduling information via plural control resource units, and

receive or transmit acknowledgement information for data indicated by the scheduling information,

wherein a resource index for the acknowledgement information is determined based on a lowest one of plural indexes indicating the plural control resource units.

12. The base station of claim 11, wherein the resource index for the acknowledgement information is determined further based on an offset.

13. The base station of claim 11, wherein the processor is further configured to control the RF unit to transmit the data indicated by the scheduling information.

14. The base station of claim 11, wherein the processor is further configured to control the RF unit to receive the data indicated by the scheduling information.

15. The base station of claim 11, wherein the plural control resource units includes control channel elements (CCEs).

16. A method for a base station to communicate control information in a wireless communication system, the method comprising:

transmitting scheduling information via plural control resource units; and

receiving or transmitting acknowledgement information for data indicated by the scheduling information,

wherein a resource index for the acknowledgement information is determined based on a lowest one of plural indexes indicating the plural control resource units.

17. The method of claim 16, wherein the resource index for the acknowledgement information is determined further based on an offset.

18. The method of claim 16, further comprising:

receiving the data indicated by the scheduling information.

19. The method of claim 16, further comprising:

transmitting the data indicated by the scheduling information.

20. The method of claim 16, wherein the plural control resource units includes control channel elements (CCEs).
