9. A transmitting device in a wireless communication system, the transmitting device comprising:
a transceiver configured to transmit or receive a signal; and
a controller coupled with the transceiver and configured to:
obtain, by a packet data convergence protocol (PDCP) layer, from an upper layer, a PDCP service data unit (SDU), the PDCP SDU including a payload,
perform, by the PDCP layer, an ethernet header compression (EHC) on an ethernet header included in payload, wherein a robust header compression (ROHC) and the EHC are configured for the PDCP layer associated with a data radio bearer (DRB) by a higher layer,
perform, by the PDCP layer, the ROHC on a transmission control protocol/internet protocol (TCP/IP) header included in the payload,
generate, by the PDCP layer, a PDCP protocol data unit (PDU), by placing an EHC header in front of a ROHC header, and by placing the ROHC header in front of the payload performed the EHC and the ROHC in the PDCP PDU, and
deliver, by the PDCP layer to a lower layer, the PDCP PDU.
