Abstract

The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

Claims

1. A method for transmitting response for random access in a base station of a mobile communication system, the method comprising:

generating a response for random access received from a terminal;

allocating the response for random access to downlink-shared radio resource for transmitting packet data; and

transmitting to the terminal an identifier indicating transmission of the response for random access through a channel carrying downlink scheduling information, and transmitting to the terminal the response for random access through the downlink-shared radio resource for transmitting packet data, wherein responses for random access for a plurality of terminals are addressed using the identifier.

2. The method as recited in claim 1, wherein the response for random access includes one or more among timing alignment (TA) information, an identifier of a random access preamble used for the random access received from the terminal, information on allocation of radio resource block to be used when uplink transmission is performed and information on power level to be used when uplink transmission is performed.

3. The method as recited in claim 1, wherein the identifier is reserved and allocated among scheduling identifiers used in the mobile communication system.

4. The method as recited in claim 1, wherein the responses for random accesses for the plurality of terminals are transmitted to the plurality of terminals.

5. The method as recited in claim 1, further comprising receiving, from the terminal, uplink transmission using information on allocation of radio resource block to be used when uplink transmission is performed, the information being included in the response for random access.

6. The method as recited in claim 5, wherein the uplink transmission is to transmit information on the terminal.

7. The method as recited in claim 1, wherein the response for random access is dynamically allocated to the downlink-shared radio resource.

8. The method as recited in claim 7, wherein information on allocation of the downlink-shared radio resource is transmitted through the channel carrying downlink scheduling information.

9. The method as recited in claim 1, wherein the response for random access is fixedly allocated to the downlink-shared radio resource.

10. A method for receiving response for random access in a terminal of a mobile communication system, the method comprising:

receiving an identifier indicating transmission of the response for random access, the identifier being transmitted through a channel carrying downlink scheduling information; and

receiving the response for random access which is addressed using the identifier through downlink shared radio resource for transmitting packet data, the identifier being used to address responses for random access for a plurality of terminals.

11. The method as recited in claim 10, wherein the response for random access includes one or more among timing alignment (TA) information, an identifier of a random access preamble used for the random access, information on allocation of radio resource block to be used when uplink transmission is performed and information on power level to be used when uplink transmission is performed.

12. The method as recited in claim 10, wherein the identifier is reserved and allocated among scheduling identifiers used in the mobile communication system.

13. The method as recited in claim 10, wherein the responses for random accesses for the plurality of terminals are transmitted to the plurality of terminals.

14. The method as recited in claim 10, further comprising performing uplink transmission using information on allocation of radio resource block to be used when uplink transmission is performed, the information being included in the response for random access.

15. The method as recited in claim 14, wherein the uplink transmission is to transmit information on the terminal to a base station.

16. The method as recited in claim 10, wherein the response for random access is dynamically allocated to the downlink-shared radio resource.

17. The method as recited in claim 16, wherein information on allocation of the downlink-shared radio resource is received through the channel carrying downlink scheduling information.

18. The method as recited in claim 10, wherein the response for random access is fixedly allocated to the downlink-shared radio resource.
