    Abstract: An operation method of a transmitting apparatus in a wireless communication system is provided. The operation method includes receiving a service data adaptation protocol (SDAP) header configuration and a header compression configuration through higher layer signaling and when an SDAP entity receives first data from an upper layer, generating an SDAP header and transmitting second data obtained by adding the generated SDAP header to the first data to a packet data convergence protocol (PDCP) entity, the generating and the transmitting being performed by the SDAP entity, performing, by the PDCP entity, header compression on an upper layer header of the second data, excluding the SDAP header, performing, by the PDCP entity, ciphering on data of the second data, excluding the SDAP header and generating a PDCP header and transmitting third data obtained by adding the generated PDCP header to the ciphered data to a lower layer, the generating and the transmitting being performed by the PDCP entity.

    Abstract: A user equipment (UE) and method thereof are provided for use in a wireless communication system. The method includes receiving, from a source cell, a radio resource control (RRC) reconfiguration message; configuring a medium access control (MAC) entity for a target cell in response to the RRC reconfiguration message configuring a bearer to a dual active protocol stack (DAPS) handover; performing, by the MAC entity, a random access procedure on the target cell for the DAPS handover; transmitting, from the MAC entity, to an upper layer, an indication of completion of the random access procedure, in response to completing the random access procedure to the target cell; and switching, by a packet data convergence protocol (PDCP) entity, uplink data for the bearer, in response to receiving a request for uplink data switching from the upper layer based on the indication.

    Abstract: Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed is an operating method of a terminal, comprising the steps of: receiving, from a base station, a radio resource control (RRC) message including information for indicating whether to use uplink data compression (UDC); receiving data from an upper application layer of the terminal; compressing the data and encoding the compressed data; generating an uplink data compression (UDC) header and a service data adaption protocol (SDAP) header together; generating a block to which the UDC header and the SDAP header are bonded in the encoded data; and transmitting the block to a lower layer of the terminal.
