Abstract

Radio communication resources are allocated in an at least partially self-organising radio communications system having several user stations and at least one central entity for organizing the allocation of radio communication resources, in addition to a corresponding radio communications system. Resources for direct communication between at least two respective user stations are allocated repeatedly at least partly by the central entity.

Claims

1-8. -8. (canceled)

9. A method for allocating radio communication resources in an at least partially self-organizing radio communication system having a plurality of user stations and at least one central entity for organizing allocation of radio communication resources, comprising:

allocating resources for a direct communication between at least two user stations in each case on a multiple basis at least partially by the at least one central entity.

10. A method according to claim 9, wherein said allocating of the radio communication resources on a multiple basis is performed by the at least one central entity when the direct communication between at least two user stations using the same resources meets certain quality requirements.

11. A method according to claim 10, wherein the radio communication resources are allocated on a multiple basis for at least two first user stations communicating with one another while using the same resources and at least two second user stations communicating with one another while using the same resources that are in each case situated in different areas of the radio communication system, between which substantially no interference exists during the direct communication while using the same resources.

12. A method according to claim 11, wherein the at least two user stations at least partially report accessible user stations to the at least one central entity for a direct radio communication.

13. A method according to claim 12, wherein the at least partially self-organizing radio communication system is a cellular radio communication system.

14. A radio communication system having a plurality of user stations, comprising:

at least one central entity at least partially organizing allocation of radio communication resources on a multiple basis for a direct communication between at least two user stations in each case.

15. A radio communication system according to claim 14, wherein said at least one central entity receives reports from the user stations at least partially indicating accessible user stations for a direct radio communication.

16. A radio communication system according to claim 15, wherein the radio communication system at least partially exhibits a cellular structure.
