Claims

1/ A method for performing resource allocation in a radio communication system, said radio communication system being dedicated to send frames on an air interface, each frame comprising a plurality of bursts, said method comprising the step of: Sorting the bursts to be contained in said frame by depending on a parameter related to the size of the resource allocated to said bursts;Performing said resource allocation depending on said sorting;Transmitting said frame in said radio communication system.

2/ The method according to claim 1, wherein the frame has a frequency extension, said sorting of the bursts being performed taking into account the frequency extension size of the resource allocated to said burst.

3/ The method according to claim 1, wherein the frame has a time extension, said sorting of the bursts being performed by taking into account the number of symbols contained in said burst.

4/ The method according to claim 1, wherein said sorting is performed in increasing order of said parameter related to the size of the resource allocated to said bursts.

5/ The method according to claim 1, wherein said sorting is performed in decreasing order of said parameter related to the size of the resource allocated to said bursts.

6/ The method according to claim 1, wherein said sorting is only performed a portion of said bursts.

7/ The method according to claim 1, wherein said radio communication system is using Orthogonal Frequency Division Multiple Access technology on the air interface, each frame having a time and frequency extension.

8/ The method according to claim 7, wherein said radio communication system uses beamforming technology at base stations.

9/ The method according to claim 1, further comprising the step of defining at least two regions in said frame, each region being adapted to contain bursts for which said parameter related to the size of the resource allocate to said burst is comprised in a predefined length range.

10/ A base station for use in a radio communication network, said base station being dedicated to send frames on an air interface, each frame comprising a plurality of bursts, said base station comprising means for scheduling the bursts in said frame;means for sorting the bursts to be contained in said frame by depending on a parameter related to the size of the resource allocated to said bursts;means for performing said resource allocation depending on said sorting;means for transmitting said frame in said radio communication system.
