A method for supporting end-to-end (e2e) Quality of Service (QoS) for uplink (UL) communication between a User Equipment (UE) and a network via a relay node, the method performed by the relay node, are provided. The method includes receiving, from the network, a downlink (DL) packet for the UE, wherein the DL packet includes a value of a first indicator of a QoS flow on a first link between the relay node and the network, and creating or updating a QoS rule, wherein the QoS rule is derived based on the value of the first indicator, and optionally wherein the created or updated QoS rule corresponds to the UE or to a QoS flow on a second link with the UE.
