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 communication system, the method comprising:

identifying control information, which is set in a binary format field, wherein the control information indicates whether a scheduling carrier on which scheduling information is transmitted is an own carrier or an other carrier compared to a data carrier on which data is received, wherein the control information indicates an index of the scheduling carrier in a case that the scheduling carrier is an other carrier;

transmitting the control information to the terminal;

transmitting the scheduling information on the scheduling carrier based on the control information; and

receiving the data based on the scheduling information on the data carrier from the terminal,

wherein a resource of scheduling information for each carrier is respectively set on the scheduling carrier, and

wherein the indication of the own carrier or the other carrier indicates whether the scheduling carrier is linked or not linked to the data carrier.

2. The method of claim 1, further comprising:

transmitting information indicating which carrier signals an acknowledge (ACK) or negative acknowledge (NACK) for the data.

3. A method for receiving control information of a terminal in a communication system, the method comprising:

receiving control information which is set in a binary format field from a base station, wherein the control information indicates whether a scheduling carrier on which scheduling information is transmitted is an own carrier or an other carrier compared to a data carrier on which data is received, wherein the control information indicates an index of the scheduling carrier in a case that the scheduling carrier is an other carrier;

receiving the scheduling information on the scheduling carrier based on the control information from the base station; and

transmitting the data based on the scheduling information on the data carrier, to the base station,

wherein a resource of scheduling information for each carrier is respectively set on the scheduling carrier, and

wherein the indication of the own carrier or the other carrier indicates whether the scheduling carrier is linked or not linked to the data carrier.

4. The method of claim 3, further comprising:

receiving information indicating which carrier signals an acknowledge (ACK) or negative acknowledge (NACK) for the data.

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

a transceiver configured to transmit and receive a signal; and

controller coupled with the transceiver and configured to;

identify control information, which is set in a binary format field, wherein the control information indicates whether a scheduling carrier on which scheduling information is transmitted is an own carrier or an other carrier compared to a data carrier on which data is received, wherein the control information indicates an index of the scheduling carrier in a case that the scheduling carrier is an other carrier;

transmit the control information to the terminal,

transmit the scheduling information on the scheduling carrier based on the control information, and

receive the data based on the scheduling information on the data carrier from the terminal,

wherein a resource of scheduling information for each carrier is respectively set on the scheduling carrier, and

wherein the indication of the own carrier or the other carrier indicates whether the scheduling carrier is linked or not linked to the data carrier.

6. The base station of claim 5, wherein the controller further controls to transmit information indicating which carrier signals an acknowledge (ACK) or negative acknowledge (NACK) for the data.

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

a transceiver configured to transmit and receive a signal; and

a controller coupled with the transceiver and configured to;

receive control information, which is set in a binary format field, wherein the control information indicates whether a scheduling carrier on which scheduling information is transmitted is an own carrier or an other carrier compared to a data carrier on which data is received, wherein the control information indicates an index of the scheduling carrier in a case that the scheduling carrier is an other carrier;

receive the scheduling information on the scheduling carrier based on the control information from the base station, and

transmit the data based on the scheduling information on the data carrier from the terminal,

wherein a resource of scheduling information for each carrier is respectively set on the scheduling carrier, and

wherein the indication of the own carrier or the other carrier indicates whether the scheduling carrier is linked or not linked to the data carrier.

8. The terminal of claim 7, wherein the controller further controls to receive information indicating which carrier signals an acknowledge (ACK) or negative acknowledge (NACK) for the data.
