Abstract: Provided is a method of performing a random access procedure, the method including: selecting, from among a plurality of Synchronization Signal Blocks (SSBs), a first SSB that exceeds a threshold value of signal power; transmitting a contention-based random access preamble corresponding to the first SSB; receiving a first Random Access Response (RAR) corresponding to the contention-based random access preamble; obtaining a first Media Access Control Protocol Data Unit (MAC PDU) corresponding to a size of uplink (UL) resource allocation in the first RAR; transmitting a message3 (Msg3) including the first MAC PDU; determining, by transmitting the Msg3, whether contention is resolved; and when the contention is not resolved, performing a contention-free random access procedure.

Abstract: Methods and apparatuses are provided for activating or deactivating packet duplication in a wireless communication system. A central unit (CU) of a first base station transmits, to a distributed unit (DU) of the first base station, via an F1 interface, information to activate or deactivate a dual connectivity (DC) based packet duplication for a data radio bearer (DRB). The information is transmitted to a second base station. A medium access control (MAC) control element (CE) indicating whether to activate or deactivate packet duplication for the DRB, based on the information, is transmitted to a user equipment (UE).

Abstract: A method and terminal are provided in which a radio resource control (RRC) message is received which includes information instructing a version change from a first packet data convergence protocol (PDCP) to a second PDCP entity. First data is transferred from the first PDCP entity to the second PDCP entity in case that the first PDCP entity is changed to the second PDCP entity, and the first PDCP entity is released. A new PDCP header associated with the transferred first data is configured. The transferred first data is encrypted with a new security key. The first data is data having a value greater than or equal to a PDCP sequence number for which successful delivery is not acknowledged, from a radio link control (RLC) entity connected to the first PDCP entity, before reception of the RRC message.
