Claim 9:
10. A base station (BS) in a wireless communication system, the BS comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving, by a Service Data Adaptation Protocol (SDAP) entity of the BS, a SDAP protocol data unit (PDU) including a SDAP header and the SDAP service data unit (SDU) from a lower layer; and
delivering, by the SDAP entity of the BS, the SDAP SDU to an upper 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.
