Apparatus and method for resource allocation information transmission in mobile communication system

An operating method of a transmitting apparatus in a wireless communication system, the method comprising:

• allocating and transmitting a first resource allocation information for at least one anchor component carrier (CC) and a second resource allocation information for at least one non-anchor CC in a first time period;
• receiving data from a receiving apparatus through the anchor CC and the non-anchor CC using the first resource allocation information and the second resource allocation information, respectively, in a second time period;
• transmitting a third resource allocation information for the non-anchor CC in a third time period, with acknowledgement (ACK) for the data transmission through the anchor CC and non-acknowledgement (NACK) for the data transmission through the non-anchor CC;
• and
• receiving retransmission data from the receiving apparatus through the non-anchor CC using the third resource allocation information in a fourth time period.

A receiving apparatus in a wireless communication system, the apparatus comprising:

• a detector;
• and
• a transmitter,
• wherein the detector is configured to detect a first resource allocation information for at least one anchor component carrier (CC) and a second resource allocation information for at least one non-anchor CC in a first time period,
• wherein the transmitter is configured to transmit data to a transmitting apparatus through the anchor CC and the non-anchor CC using the first resource allocation information and the second resource allocation information, respectively, in a second time period,
• wherein the detector is configured to detect a third resource allocation information for the non-anchor CC in a third time period, at which acknowledgement (ACK) for the data transmission through the anchor CC and non-acknowledgement (NACK) for the data transmission through the non-anchor CC are received, and
• wherein the transmitter is configured to retransmit the data to the transmitting apparatus through the non-anchor CC using the third resource allocation information in a fourth time period.

A transmitting apparatus in a wireless communication system, the apparatus comprising:

• an allocator;
• a transmitter;
• and
• a receiver,
• wherein the allocator is configured to allocate a first resource allocation information for at least one anchor component carrier (CC) and a second resource allocation information for at least one non-anchor CC in a first time period,
• wherein the transmitter is configured to transmit the first resource allocation information for the anchor CC and the second resource allocation information for the non-anchor CC to a receiving apparatus,
• wherein the receiver is configured to receive data from the receiving apparatus through the anchor CC and the non-anchor CC using the first resource allocation information and the second resource allocation information, respectively, in a second time period,
• wherein the transmitter is configured to transmit a third resource allocation information for the non-anchor CC in a third time period, with acknowledgement (ACK) for the data transmission through the anchor CC and non-acknowledgement (NACK) for the data transmission through the non-anchor CC, and
• wherein the receiver is configured to receive retransmission data from the receiving apparatus through the non-anchor CC using the third resource allocation information in a fourth time period.
