Carrier Aggregation Aware Load Distribution
First Claim
1. A method, performed in a source network node of a source cell, of supporting load distribution from a source cell to a target cell in a wireless network using carrier aggregation, the method comprising:
- determining source traffic load and carrier aggregation properties of the source cell,receiving, from a target network node, a load report comprising target traffic load and carrier aggregation properties for the target cell,retrieving user equipment, UE, carrier aggregation capabilities of UEs served by the source cell; and
selecting one or more UEs served by the source cell for moving to the target cell based on a combination of the retrieved UE carrier aggregation capabilities and the carrier aggregation properties of the source cell and target cell.

Abstract
The present disclosure relates to methods and network nodes of supporting load distribution from a source cell to a target cell in a wireless network using carrier aggregation. When performed in the source network node, the method comprises determining (S31) source traffic load and carrier aggregation properties of the cell source cell and receiving (S32), from a target network node, a load report comprising target traffic load and carrier aggregation properties for the target cell. Carrier aggregation capabilities of user equipments, UEs, served by the source cell are retrieved in the source network node. One or more UEs served by the source cell are selected (S33) for moving to the target cell based on a combination of the retrieved UE carrier aggregation capabilities and the carrier aggregation properties of the source cell and target cell.

12. A method, performed in a target network node of a target cell, of supporting load distribution from a source cell to the target cell in a wireless network using carrier aggregation, the method comprising:
-
determining target traffic load and carrier aggregation properties of the target cell, sending, to the source network node, a load report comprising the determined target traffic load and carrier aggregation properties thereby enabling selection in the receiving source network node of one or more UEs served by the source cell for moving to the target cell. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A network node of a source cell, arranged to support load distribution from the source cell to a target cell, the network node comprising a processor, a communication interface, and a memory, said memory containing instructions executable by said processor whereby the network node is operative to:
-
determine source traffic load and carrier aggregation properties of the source cell, receive, from a target network node, a load report comprising target traffic load and carrier aggregation properties determined for the target cell, retrieve user equipment, UE, carrier aggregation capabilities of UEs served by the source cell; and select one or more UEs served by the source cell for moving to the target cell based on a combination of the retrieved UE carrier aggregation capabilities and the carrier aggregation properties of the source cell and target cell. - View Dependent Claims (23, 24, 25)
