1. A method for improving flow control interaction in a distributed radio access network, RAN, comprising an upper layer RAN node and at least one lower layer RAN node, the method comprising:
determining a Packet Data Convergence Protocol, PDCP, Protocol Data Unit, PDU, buffer dwell time target, BDTT;
determining the BDTT is performed in the upper layer RAN node;
providing the BDTT to at least one of the upper layer RAN node and the lower layer RAN node, the BDTT being at least one of differentiated and determined based on Quality of Service, Qos, requirements, providing the BDTT comprising providing the BDTT from the upper layer RAN node to the at least one lower layer RAN node; and
selecting a Desired Buffer Size, DBS, in the lower layer RAN node based on the BDTT.
