PDCP AND FLOW CONTROL FOR SPLIT BEARER

摘要

A method in a network node is disclosed. The method comprises sending one or more packet data convergence protocol (PDCP) packet data units (PDUs) to a second network node on an internode interface, each of the one or more PDUs having an associated PDCP sequence number and an associated internode interface specific sequence number, the mtemode interface specific sequence numbers assigned by the network node. The method further comprises receiving feedback from the second network node.
