1. A method for processing a data unit by a Service Data Adaptation Protocol (SDAP) entity of a user equipment (UE) in a wireless communication system, the method comprising:
receiving a SDAP Service Data Unit (SDU) from an upper layer;

submitting the SDAP PDU to a lower layer,
wherein the SDAP header includes a Quality of Service (QoS) Flow Identifier (QFI) field,
wherein, based on the QFI field being a specific value, the SDAP header further includes an extended QFI field having a value corresponding to the SDAP SDU, and
wherein, based on the QFI field not being the specific value, the SDAP header does not include the extended QFI field and the QFI field has the value corresponding to the SDAP SDU.
