QOS management framework

A method of managing Quality of Service (QoS), the method comprising: identifying, by a first node, wherein the first node is a radio access network (RAN) node, a number of hops for a bearer from a location in a multi-hop network to a destination in the multi-hop network; configuring, by the first node, information on a Packet Delay Budget (PDB) per hop for at least one second node between the location and the destination, based on the identified number of hops and a PDB of the bearer; and transmitting, by the first node, QoS information including the information on the PDB per hop to one or more second nodes between the location and the destination. The location may correspond to an attachment location of a user equipment (UE) or a location of a third node in the multi-hop network. The method may further comprise determining an effective PDB per hop based on obtained network condition information from the second nodes e.g. a number of hops to a destination, congestion conditions, radio conditions, buffer status, wireless delay, end-to-end (E2E) flow control feedback. Also provided is a first node and computer programs for executing the method.
