Systems and methods for distributing relay wireless devices across an access node
Exemplary embodiments described herein include systems, methods, and nodes for distributing relay wireless devices across an access node. Network identification numbers associated with at least two wireless devices may be determined. At an access node, a traffic class identifier and frequency band may be assigned to the at least two wireless devices, wherein each frequency band available for communication at the access node is assigned at most a maximum number of wireless devices comprising a network identification number that meets the criteria. Data may then be communicated between the access node and the at least two wireless devices according to the assigned traffic class identifiers and frequency bands, wherein the wireless devices comprise relay wireless devices that relay data between the access node and one or more small cells.

4. The method of claim 1 , wherein traffic of a first type is transmitted from the access node to the first wireless device according to the first traffic class identifier based on a first frequency band, and traffic of a second type is transmitted from the access node to the second wireless device according to the second traffic class identifier based on a second frequency band.
5. The method of claim 4 , wherein traffic of the first type is not transmitted over the second frequency band to the second wireless device and traffic of the second type is not transmitted over the first frequency band to the first wireless device.
6. The method of claim 5 , wherein traffic of the first type comprises carrier aggregation traffic and traffic of the second type comprises traffic with a latency requirement that meets a latency criteria.
7. The method of claim 4 , further comprising determining a network identification number associated with a third wireless device; and
assigning the first traffic class identifier and a third frequency band to the third wireless device when the determined network identification number for the third wireless device matches a predetermined identification number.
8. The method of claim 7 , wherein traffic of the first type and the second type is transmitted from the access node to the third wireless device according to the first traffic class identifier based on the third frequency band.
9. The method of claim 8 , wherein at least two of the first, second, and third wireless devices serve as a relay node for a same small cell.
10. The method of claim 1 , wherein the maximum number of wireless devices comprises one wireless device.
