Abstract

A method and apparatus for transmitting uplink control information in a wireless communication system is disclosed. A method for transmitting uplink control information in a mobile station of a wireless communication system includes performing reverse repetition coding with respect to first uplink control information, and performing joint coding with respect to the reverse repetition coded first uplink control information and second uplink control information. The first uplink control information has higher priority than the second uplink control information.

Claims

1. A method for transmitting uplink control information in a mobile station of a wireless communication system, the method comprising:

performing reverse repetition coding with respect to first uplink control information; and

performing joint coding with respect to the reverse repetition coded first uplink control information and second uplink control information, wherein the first uplink control information has higher priority than the second uplink control information.

2. The method according to claim 1, wherein the first uplink control information and the second uplink control information are transmitted in one transmission format.

3. The method according to claim 2, wherein the performing the reverse repetition coding includes performing reverse repetition coding such that the number of bits of the first uplink control information becomes a predetermined bit number.

4. The method according to claim 3, wherein the predetermined bit number is set in consideration of a maximum payload size supportable by channel coding defined in the transmission format.

5. The method according to claim 2, wherein the performing the reverse repetition coding includes performing reverse repetition coding such that a sum of the numbers of bits of the first uplink control information and the second uplink control information becomes a predetermined bit number.

6. The method according to claim 1, wherein the first uplink control information is a Scheduling Request (SR) and the second uplink control information is an Acknowledgement/Non-Acknowledgement (ACK/NACK) signal.

7. The method according to claim 6, wherein the first uplink control information is set to 1 if a scheduling request is present as positive Scheduling Request (SR) transmission in the mobile station and is set to 0 if the scheduling request is absent as negative Scheduling Request (SR) transmission in the mobile station.

8. The method according to claim 1, wherein the first uplink control information is a Scheduling Request (SR) and the second uplink control information is a Channel Quality Indicator (CQI).

9. The method according to claim 1, wherein the first uplink control information is an Acknowledgement/Non-Acknowledgement (ACK/NACK) signal and the second uplink control information is a Channel Quality Indicator (CQI).

10. A mobile station of a wireless communication system, comprising:

a processor configured to perform reverse repetition coding with respect to first uplink control information and joint coding with respect to the reverse repetition coded first uplink control information and second uplink control information; and

a transmission module configured to transmit the joint coded first uplink control information and second uplink control information, wherein the first uplink control information has higher priority than the second uplink control information.

11. The mobile station according to claim 10, wherein the first uplink control information and the second uplink control information are transmitted in one transmission format.

12. The mobile station according to claim 11, wherein the reverse repetition coding is performed such that the number of bits of the first uplink control information becomes a predetermined bit number.

13. The mobile station according to claim 12, wherein the predetermined bit number is set in consideration of a maximum payload size supportable by channel coding defined in the transmission format.

14. The mobile station according to claim 11, wherein the reverse repetition coding is performed such that a sum of the numbers of bits of the first uplink control information and the second uplink control information becomes a predetermined bit number.

15. The mobile station according to claim 10, wherein the first uplink control information is a Scheduling Request (SR) and the second uplink control information is an Acknowledgement/Non-Acknowledgement (ACK/NACK) signal.

16. The mobile station according to claim 15, wherein the first uplink control information is set to 1 if a scheduling request is present as positive Scheduling Request (SR) transmission in the mobile station and is set to 0 if the scheduling request is absent as negative Scheduling Request (SR) transmission in the mobile station.

17. The mobile station according to claim 10, wherein the first uplink control information is a Scheduling Request (SR) and the second uplink control information is a Channel Quality Indicator (CQI).

18. The mobile station according to claim 10, wherein the first uplink control information is an Acknowledgement/Non-Acknowledgement (ACK/NACK) signal and the second uplink control information is a Channel Quality Indicator (CQI).
