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 of determining resource allocation for acknowledgement/negative acknowledgement (ACK/NACK) signal at a mobile communication apparatus, the method comprising:

transmitting two uplink data blocks by using scheduled resource blocks (RBs);

determining ACK/NACK resource for an ACK/NACK signal corresponding to 1^st uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to a lowest RB index of the scheduled RBs; and

determining ACK/NACK resource for an ACK/NACK signal corresponding to 2^nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.

2. The method of claim 1, wherein the two uplink data blocks are corresponding to two uplink codewords.

3. The method of claim 1, wherein information indicating the scheduled RBs is provided using one or more control channel elements (CCEs).

4. The method of claim 1, further comprising:

receiving ACK/NACK signals for the two uplink data blocks using the determined ACK/NACK resources.

5. A method of performing resource allocation for acknowledgement/negative acknowledgement (ACK/NACK) signal at a network node, the method comprising:

receiving two uplink data blocks by using scheduled resource blocks (RBs),

determining ACK/NACK resource for an ACK/NACK signal corresponding to 1^st uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to a lowest RB index of the scheduled RBs; and

determining ACK/NACK resource for an ACK/NACK signal corresponding to 2^nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.

6. The method of claim 5, wherein the two uplink data blocks are corresponding to two uplink codewords.

7. The method of claim 5, wherein information indicating the scheduled RBs is provided using one or more control channel elements (CCEs).

8. The method of claim 5, further comprising:

transmitting ACK/NACK signals for the two uplink data blocks using the determined ACK/NACK resources.

9. A mobile communication apparatus which is used in determining resource allocation for acknowledgement/negative acknowledgement (ACK/NACK) signal, the mobile communication apparatus comprising:

a memory unit; and

a processor,

wherein the processor is configured to;

transmit two uplink data blocks by using scheduled resource blocks (RBs);

determine ACK/NACK resource for an ACK/NACK signal corresponding to 1^st uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to a lowest RB index of the scheduled RBs; and

determine ACK/NACK resource for an ACK/NACK signal corresponding to 2^nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.

10. The mobile communication apparatus of claim 9, wherein the two uplink data blocks are corresponding to two uplink codewords.

11. The mobile communication apparatus of claim 9, wherein information indicating the scheduled RBs is provided using one or more control channel elements (CCEs).

12. The mobile communication apparatus of claim 9, wherein the processor is further configured to receive ACK/NACK signals for the two uplink data blocks using the determined ACK/NACK resources.

13. A network node which is used in performing resource allocation for acknowledgement/negative acknowledgement (ACK/NACK) signal, the network node comprising:

a memory unit; and

a processor,

wherein the processor is configured to;

receive two uplink data blocks by using scheduled resource blocks (RBs);

determine ACK/NACK resource for an ACK/NACK signal corresponding to 1^st uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to a lowest RB index of the scheduled RBs; and

determine ACK/NACK resource for an ACK/NACK signal corresponding to 2^nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.

14. The network node of claim 13, wherein the two uplink data blocks are corresponding to two uplink codewords.

15. The network node of claim 13, wherein information indicating the scheduled RBs is provided using one or more control channel elements (CCEs).

16. The network node of claim 13, wherein the processor is further configured to transmit ACK/NACK signals for the two uplink data blocks using the determined ACK/NACK resources.
