Abstract

A resource allocation method and a method for transmitting resource allocation information in a mobile communication system are disclosed. That is, a LVRB (PRB) and a DVRB which are the units of a scheduling resource are defined and a resource allocation method and a method for transmitting resource allocation information using the same are disclosed. In the LVRB, a part bitmap scheduling method using a LVRB set is suggested and a method for constructing resource allocation information using the same is suggested. In the DVRB, a method for defining the DVRB using PRBs in a subframe is suggested and a method for constructing resource allocation information using the same when scheduling is performed using the DVRB constructed by the defined method is suggested. In order to prevent interference and collision from occurring due to the complete matching of the DVRBs in respective cells, a method using different DVRBs in the respective cells is suggested.

Claims

1. A method for receiving resource allocation information in mobile communication system, the method comprising:

receiving first information and second information via a control channel, the first information indicating a resource block group set and the second information indicating whether or not to allocate resource block included in the resource block group set in form of a bitmap;

identifying allocated resource block from the first information and the second information; and

receiving data using the allocated resource block.

2. The method according to claim 1, wherein the first information indicates one among one or more resource block group set.

3. The method according to claim 1, wherein the resource block group set includes one or more resource block group.

4. The method according to claim 3, wherein the resource block group includes one or more consecutive resource block according to the number of resource blocks included in a subframe.

5. The method according to claim 4, wherein the number of the resource block group set corresponds with the number of resource block included in the resource block group.

6. The method according to claim 4, wherein the number of resource blocks included in the resource block group set corresponds with the number of resource block group.

7. A method for transmitting resource allocation information in mobile communication system, the method comprising:

constructing a control channel including first information which indicates resource allocation type and second information which is a bitmap indicating whether or not to allocate at least part of resource blocks included in a subframe according to the resource allocation type;

transmitting the control channel to a scheduled User Equipment; and

transmitting data associated with the control channel to the scheduled User Equipment,

wherein the resource allocation type indicates at least one of a group scheduling type and a part-bitmap scheduling type.

8. The method according to claim 7, the bitmap indicates a resource block that is allocated to the scheduled User Equipment among one or more resource block included in a resource block group set, in a case that the resource allocation type is the part-bitmap scheduling type.

9. The method according to claim 8, wherein the resource block group set includes one or more resource block group.

10. The method according to claim 9, wherein the resource block group includes one or more consecutive resource block according to the number of resource blocks included in the subframe.

11. The method according to claim 8, wherein the control channel further comprises third information which indicates one among one or more resource block group set.

12. The method according to claim 7, wherein the bitmap indicates a resource block group that is allocated to the scheduled User Equipment, in a case that the resource allocation type is the group scheduling type.

13. A method for receiving resource allocation information in mobile communication system, the method comprising:

receiving information of virtual resource block which comprises a part of each of one or more resource block in a subframe;

identifying allocated resource block from the information of virtual resource block; and

receiving data using at least part of the allocated resource block according to the information of virtual resource block.

14. The method according to claim 13, wherein the information of virtual resource block includes information of the one or more resource block and information which indicates one or more among one or more virtual resource block comprised by the one or more resource block.

15. The method according to claim 13, wherein the information of virtual resource block includes information of the number of the one or more resource block and information of the number of one or more virtual resource block comprised by the one or more resource block and information which indicates one or more among the one or more virtual resource block.
