Abstract: Provided is a first terminal for performing unicast communication between terminals in a wireless communication system. The first terminal may be configured to: transmit a packet to a second terminal through a first sidelink carrier; determine a failure of the first sidelink carrier based on at least one of a number of times of retransmission of the transmitted packet, a number of times of reception of hybrid automatic repeat request (HARQ) negative acknowledgement (NACK) or discontinuous transmission (DTX) for the transmitted packet, or a number of times of continuous out of synch (OOS) for the first sidelink carrier; and determine whether to perform a radio link failure (RLF) handling procedure or whether to perform a carrier failure handling procedure, based on a result of the determining of the failure and the first sidelink carrier, wherein the carrier failure handling procedure may be performed based on at least one of a connection state between the first terminal and a base station or a need for multi-carrier transmission.

Abstract: Provided are a method and device for providing power preference information in a wireless communication system. A terminal according to an embodiment of the disclosure may identify the necessity for transition from a radio resource control (RRC) connected mode and transmit, to a base station, a connection release request message including state information preferred by the terminal. In this case, the state information preferred by the terminal may include information indicating whether a state preferred by the terminal is an idle mode, an inactive mode, a connected mode, or a random mode, and the random mode may indicate that the terminal prefers to be released from the connection mode but there is no preferred mode among the idle mode and the inactive mode.

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 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 processing a packet by a transmission device in a wireless communication system according to an embodiment of the present invention comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QoS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.

Abstract: The purpose of the present invention is to provide a method for increasing data transmission efficiency when performing packet duplication. A method for a terminal in a wireless communication system according to the present invention comprises the steps of: performing protocol data convergence protocol (PDCP) duplication in which an identical PDCP protocol data unit (PDU) is transmitted to a base station through each of a first logical channel and a second logical channel; when a request for retransmission of the PDCP PDU which has been transmitted through the second logical channel is received from the base station, retransmitting the PDCP PDU to the base station; and when the PDCP PDU has been retransmitted a predetermined number of times or more, receiving, from the base station, information indicating deactivation of the PDCP duplication.

Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method for operating a user equipment in a wireless communication system includes determining service information required by a vehicle to everything (V2X) application and determining a V2X transmission mode. The method also includes determining quality of service (QoS) information required by the V2X application and acquiring sidelink radio bearer configuration information corresponding to the QoS information. The method further includes transmitting and receiving a V2X packet of direct communication using the acquired sidelink radio bearer configuration information.
