Claim Text:
1. A method of coordinated scheduling of a downlink transmission flow from a first radio network node to a user equipment UE in a second radio network node, the method comprising steps of: scheduling the downlink transmission flow so that in-sequence delivery of received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node; determining, based on one or more buffer-related parameters, that in-sequence delivery of data blocks to higher layers in the UE can reach an acceptable level even without adjusting scheduling priority of the downlink transmission flow in the second radio network node, or that there may be out-of-sequence delivery of received data blocks to the higher layers in the UE with adjusting the scheduling priority of the downlink transmission flow in the second radio network node; and resetting the scheduling priority of the downlink transmission flow to an original scheduling priority in the second radio network node, or recalculating the scheduling priority of the downlink transmission flow without considering the scheduling priority adjustment.
