1. A method performed by a terminal, the method comprising:
receiving, from a base station, a radio resource control (RRC) message comprising information indicating to apply uplink data compression (UDC);
obtaining data and a service data adaptation protocol (SDAP) header in a packet data convergence protocol (PDCP) layer of the terminal, from an upper layer of the terminal;
performing the UDC for the data in the PDCP layer of the terminal based on the information indicating to apply the UDC, wherein the UDC is not performed on the SDAP header;
ciphering a block including a UDC header and the UDC performed data; and
delivering a PDCP packet data unit (PDCP PDU) from the PDCP layer of the terminal to a lower layer of the terminal,
wherein the PDCP PDU includes a PDCP header, the SDAP header, and the ciphered block.
