Method for receiving ACK/NACK signal in mobile communication system

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 1st 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 2nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.

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 1st 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 2nd uplink data block, wherein the ACK/NACK resource is linked to a value corresponding to the lowest RB index plus an offset.
