ABSTRACT:
The present invention relates to a method and system for scheduling data packets in a base station device of an access network. An information indicating a retransmission status of a data packet is provided to the base station device, and a scheduling priority is allocated to the data packet based on the retransmission status information. Thereby, retransmission packets can be scheduled earlier and round trip times can be reduced, so as to decrease the risk of timeouts and stalling and to loosen buffer requirements.
