Abstract

A method and apparatus are provided for receiving acknowledgement information by a base station in a wireless communication system. The method includes transmitting control information for uplink transmission of acknowledgement information, the control information including at least one of information associated with a cyclic shift of a sequence or information for identifying a first resource block (RB) to be used for the uplink transmission of the acknowledgement information; and receiving the acknowledgement information from a user equipment based on the control information.

Claims

1. A method for receiving uplink control information by a base station in a wireless communication system, the method comprising:

transmitting configuration information for transmission of the uplink control information including acknowledgement information, the configuration information including information associated with a cyclic shift of a sequence to be used for the transmission of the uplink control information and information for identifying a first resource block (RB) to be used for the transmission of the acknowledgement information; and

receiving the uplink control information including the acknowledgement information on a physical uplink control channel based on the configuration information, the acknowledgement information being received from a user equipment in response to a downlink transmission of the base station.

2. The method of claim 1, wherein receiving the uplink control information comprises:

receiving channel quality indication (CQI) information at both ends of a system bandwidth; and

receiving the acknowledgement information at an interior of the system bandwidth based on the information for identifying the first RB.

3. The method of claim 1, wherein a resource for the acknowledgement information is placed between resources for channel quality indication (CQI) information in a system bandwidth.

4. The method of claim 1, wherein the information associated with the cyclic shift includes offset information for the cyclic shift and information indicating the cyclic shift.

5. The method of claim 1, wherein the information for identifying the first RB is associated with channel quality indication (CQI) information.

6. A base station for receiving uplink control information in a wireless communication system, the base station comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

transmit configuration information for transmission of the uplink control information including acknowledgement information, the configuration information including information associated with a cyclic shift of a sequence to be used for the transmission of the uplink control information and information for identifying a first resource block (RB) to be used for the transmission of the acknowledgement information, and

receive the uplink control information including the acknowledgement information on a physical uplink control channel based on the configuration information, the acknowledgement information being received from a user equipment in response to a downlink transmission of the base station.

7. The base station of claim 6, wherein the controller is further configured to:

receive channel quality indication (CQI) information at both ends of a system bandwidth, and

receive the acknowledgement information at an interior of the system bandwidth based on the information for identifying the first RB.

8. The base station of claim 6, wherein a resource for the acknowledgement information is placed between resources for channel quality indication (CQI) information in a system bandwidth.

9. The base station of claim 6, wherein the information associated with the cyclic shift comprises offset information for the cyclic shift and information indicating the cyclic shift.

10. The base station of claim 6, wherein the information for identifying the first RB is associated with channel quality indication (CQI) information.

11. A method for transmitting uplink control information by a user equipment in a wireless communication system, the method comprising:

receiving configuration information for transmission of the uplink control information including acknowledgement information, the configuration information including information associated with a cyclic shift of a sequence to be used for the transmission of the uplink control information and information for identifying a first resource block (RB) to be used for the transmission of the acknowledgement information; and

transmitting the uplink control information including the acknowledgement information on a physical uplink control channel based on the configuration information, the acknowledgement information being transmitted in response to a downlink transmission of a base station.

12. The method of claim 11, wherein transmitting the uplink control information comprises:

transmitting channel quality indication (CQI) information at both ends of a system bandwidth; and

transmitting the acknowledgement information at an interior of the system bandwidth based on the information for identifying the first RB.

13. The method of claim 11, wherein a resource for the acknowledgement information is placed between resources for channel quality indication (CQI) information in a system bandwidth.

14. The method of claim 11, wherein the information associated with the cyclic shift includes offset information for the cyclic shift and information indicating the cyclic shift.

15. The method of claim 11, wherein the information for identifying the first RB is associated with channel quality indication (CQI) information.

16. A user equipment (UE) for transmitting uplink control information in a wireless communication system, the UE comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

receive configuration information for transmission of the uplink control information including acknowledgement information, the configuration information including information associated with a cyclic shift of a sequence to be used for the transmission of the uplink control information and information for identifying a first resource block (RB) to be used for the transmission of the acknowledgement information; and

transmit the uplink control information including the acknowledgement information on a physical uplink control channel based on the configuration information, the acknowledgement information being transmitted in response to a downlink transmission of a base station.

17. The UE of claim 16, wherein the controller is further configured to:

transmit channel quality indication (CQI) information at both ends of a system bandwidth, and

transmit the acknowledgement information at an interior of the system bandwidth based on the information for identifying the RB.

18. The UE of claim 16, wherein a resource for the acknowledgement information is placed between resources for channel quality indication (CQI) information in a system bandwidth.

19. The UE of claim 16, wherein the information associated with the cyclic shift comprises offset information for the cyclic shift and information indicating the cyclic shift.

20. The UE of claim 16, wherein the information for identifying the first RB is associated with channel quality indication (CQI) information.
