1. A method performed by a user plane entity of a distributed base station, the method comprising:
receiving, from a user equipment (UE), an uplink data packet corresponding to a data flow, the uplink data packet comprising a specific Quality of Service (QoS) Flow Identifier (QFI);
determining that the QFI in the uplink data packed is not configured;
transmitting, to a control plane entity of the distributed base station, information indicating that the QFI in the uplink data packed is not configured; and
transmitting, to the UE via a data radio bearer (DRB), a downlink data packet corresponding to the data flow, the downlink data packet comprising one octet header information comprising a Reflective QoS flow to DRB mapping Indication (RDI), a Reflective QoS Indication (RQI), and the QFI;
wherein the RDI causes the UE to update mapping between the data flow and the DRB, and
wherein the information indicating that the QFI in the uplink data packed is not configured comprises a list including at least one combination of a Protocol Data Unit (PDU) session Identifier (ID) and a QoS Flow List.
