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 uplink control information in a mobile communication system, comprising the steps of:

a) generating uplink control information;

b) allocating the uplink control information on downlink-shared radio resource for packet data transmission based on downlink scheduling information; and

c) transmitting the radio resource to a terminal.

2. The method of claim 1, wherein the downlink scheduling information includes a group identifier denoting a terminal group to receive the uplink control information, and radio resource block location information denoting a location of the downlink-shared radio resource where the uplink control information is allocated.

3. The method of claim 2, wherein a predetermined part of a terminal scheduling identifier is reserved and allocated as the group identifier.

4. The method of claim 1, wherein in the step b), the uplink control information is variably local-allocated on the downlink radio resource using the downlink scheduling information.

5. The method of claim 1, wherein in the step b), the uplink control information is variably distributed and allocated on the downlink radio resource based on the downlink scheduling information.

6. The method of claim 1, wherein the uplink control information includes at least one among uplink scheduling information, random access response information, and response information for sustaining uplink synchronization.

7. The method of claim 6, wherein the uplink scheduling information includes a scheduling identifier, a radio resource block location information of the uplink control information, and an allocation period information.

8. The method of claim 6, wherein the random access response information includes a terminal identifier and uplink radio resource block location information.

9. The method of claim 1, wherein in the step b) the uplink control information is fixedly allocated to downlink radio resource.

10. The method of claim 9, further comprising the step of:

transmitting radio resource fixed allocation information of uplink control information to a terminal through a broadcasting channel (BCH).

11. A method for transmitting random access response information of a mobile communication system, comprising the steps of:

a) generating random access response information; and

b) allocating the random access response information on downlink-shared radio resource using downlink scheduling information,

wherein the downlink scheduling information includes a group identifier denoting a terminal or a terminal group to receive the random access response information.

12. The method of claim 11, wherein the random access response information includes at least one among a terminal identifier, timing alignment information, and uplink radio resource block location information.

13. The method of claim 11, wherein a predetermined part of a scheduling identifier is reserved and used as the group identifier.

14. The method of claim 11, wherein in the step b), random access response information for at least one terminal is allocated to a downlink-shared radio resource.

15. A method for receiving random access response information of a mobile communication system, comprising the steps of:

a) receiving a downlink-shared radio resource; and

b) obtaining random access response information from the downlink-shared radio resource based on downlink scheduling information,

wherein the downlink scheduling information includes a group identifier denoting a terminal or a terminal group to receive the random access response information.

16. The method of claim 15, wherein the random access response information includes at least one among a terminal identifier, timing alignment information, and uplink radio resource block location information.

17. The method of claim 15, wherein a predetermined part of a scheduling identifier is reserved as the group identifier.

18. The method of claim 15, wherein random access response information for at least one terminal is allocated to the downlink-shared radio resource.
