A method and a device for data processing in a wireless network are provided, wherein at least one relay node is served by a base station, wherein load partitioning for the at least one relay node is conducted based on at least one load information message, and wherein the at least one load information message includes information regarding resource blocks and sub-frames. Furthermore, a communication system is suggested including at least one such device.

No: 13/578041 Application Filed: February 10, 2010 Claim: 1. A method for data processing in a wireless network, wherein at least one relay node is served by a base station, wherein load partitioning for the at least one relay node is conducted based on at least one load information message, wherein the at least one load information message comprises information regarding resource blocks and sub-frames. Claim: 2. The method according to claim 1, wherein the at least one load information message is based on a high interference indication message and/or on an overload indication message. Claim: 3. The method according to claim 1, wherein the resource block comprises at least one group of resource blocks and/or wherein the sub-frames comprises at least one group of sub-frames. Claim: 4. The method according to claim 1, wherein the load information message is sent from the relay node to the base station comprising a partitioning request information. Claim: 5. The method according to claim 4, wherein the partitioning request information comprises resource blocks and sub-frames that are preferred by the relay node. Claim: 6. The method according to claim 4, wherein the partitioning request information comprises additional resource blocks and sub-frames that are preferred by the relay node, wherein the resource blocks and sub-frames requested extend beyond what is currently required by the relay node for conveying data. Claim: 7. The method according to claim 1, wherein the load information message is sent from the relay node to the base station comprising an information about the interference levels. Claim: 8. The method according to claim 1, wherein the load information message is sent from the base station to the relay node comprising load partitioning information, wherein the relay node utilizes this load partitioning information. Claim: 9. The method according to claim 8, wherein the load information message is sent from the base station to the relay node comprising information on resources the base station assigned to other relay nodes and/or resources used by the base station itself. Claim: 10. The method according to claim 1, wherein the at least one load message comprises a bitmap information indicating the resource blocks and sub-frames. Claim: 11. The method according to claim 1, wherein the bitmap information is compressed. Claim: 12. The method according to claim 11, wherein the bitmap information is compressed depending on a traffic situation on a backhaul link and/or an overhead traffic threshold on the backhaul link. Claim: 13. The method according to claim 1, wherein the wireless network is a 3GPP wireless network, in particular an LTE-A network. Claim: 14. A device for data processing in a wireless network comprising a processing unit that is arranged, for conducting load partitioning for at least one relay node based on at least one load information message, wherein the at least one relay node is served by a base station, and wherein the at least one load information message comprises information regarding resource blocks and sub-frames. Claim: 15. A communication system comprising at least one device according to claim 14. Current U.S. Class: 370/315 Current International Class: 04
