Claim:
1. A method in a transmitting radio node for scheduling service data flows within a radio bearer towards a receiving radio node in a radio communications network, the method comprising: mapping data packets of at least two service data flows within the radio bearer to a respective pre-scheduling queue at a Packet Data Convergence Protocol (PDCP) layer, wherein each pre-scheduling queue is associated with a service or a service quality requirement of the respective service data flow; pre-scheduling the data packets of the respective pre-scheduling queue down to a scheduling queue at a Radio Link Control (RLC) or a Medium Access Control (MAC) layer; and scheduling the data packets in the scheduling queue towards the receiving radio node, wherein the pre-scheduling and/or the scheduling takes a prebuffer time of a data packet queued in the pre-scheduling queue into account when pre-scheduling and/or scheduling the data packets.
