    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on 5G communication technology and IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A handover method of a terminal in a mobile communication system according to the present disclosure includes transmitting UE capability information including a random access-free handover indicator to a first base station, receiving a handover command message from the first base station, and transmitting, when the handover command message includes uplink resource information, a handover complete message to a second base station based on the uplink resource information.

    Abstract: The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for transmitting information in a communication system is provided. The method includes receiving information for allocating at least two transmission resources, allocating at least two transmission resources, identifying a data unit corresponding to at least one logical channel, determining a size of the data unit, which is to be transmitted based on a size of the allocated at least two transmission resources, and transmitting data to a receiver based on the determined size of the data unit.

    Abstract: The disclosure relates to a method and apparatus for controlling packet duplication transmission in a wireless communication system. According to an embodiment of the disclosure, a method, performed by a user equipment (UE), of controlling packet duplication transmission in a wireless communication system includes: receiving a packet duplication configuration for a radio bearer, through a radio resource control (RRC) message, from a base station; determining whether each of a plurality of radio link control (RLC) entities is configured to be used for uplink packet duplication transmission; and performing, when packet duplication transmission is activated, packet duplication transmission by using a RLC entity set to be used for uplink packet duplication transmission.

    Abstract: A method and terminal are provided in which a radio resource control (RRC) message is received which includes information indicating a change from a first packet data convergence protocol (PDCP) to a second PDCP entity. It is identified whether the first PDCP entity is changed based on the information indicating the change. Data with a PDCP sequence number for the first PDCP entity is processed as new data for the second PDCP entity, in case that the first PDCP entity is changed. The first PDCP entity is released. A new PDCP header associated with the data is configured. The data is encrypted with a new security key. The PDCP sequence number of the first PDCP entity is greater than or equal to the PDCP sequency number of data for which successful transmission is not acknowledged from a radio link control (RLC) entity.
