    摘要: The disclosure relates to a 5th generation (5G) communication system or a 6th generation (6G) communication system for supporting higher data rates. More particularly, the disclosure relates to a method performed by a terminal in a communication system comprising receiving, from a base station, a radio resource control (RRC) message including a first value of a first timer and a second value of a second timer for low importance; receiving, from the base station, a medium access control (MAC) control element (CE) for activating a protocol data unit (PDU) set importance (PSI) based discard; starting the second timer based on reception of a packet data convergence protocol (PDCP) service data unit (SDU) belonging to a low importance PDU set; and discarding the PDCP SDU belonging to the low importance PDU set based on an expiration of the second timer.

    摘要: 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. The disclosure is to configure configuration parameter information of a sidelink radio bearer in a wireless communication system. An operation of a terminal may include: determining whether there is a need of an SLRB configuration; obtaining the SLRB configuration; performing sidelink data transmission or reception by using the SLRB configuration; determining whether there is a collision of the SLRB configuration; and performing a procedure of adjusting the collision of the SLRB configuration.

    摘要: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station, configuration information associated with a sidelink (SL) listen-before-talk (LBT) failure recovery, identifying a counter value associated with the SL LBT failure detection, based on an SL LBT failure indication received from a lower layer, and in a case where the counter value is greater than or equal to a threshold value, triggering the SL consistent LBT failure.

    摘要: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system to support a data transmission rate higher than before. Disclosed is a method performed by a first user equipment (UE), including obtaining configuration information including information on a threshold used for identifying, by the first UE performing a UE-to-UE (U2U) relay operation, whether to perform transmission of a second message based on a first message received by the first UE from a second UE, receiving, from the second UE, a first discovery message including information on the second UE, identifying, based on reference signal received power (RSRP) measured based on communication with the second UE and the threshold, whether to perform transmission of the second message based on the received first discovery message, and performing, based on a result of the identification, transmission of the second message based on the received first discovery message.

    摘要: The present disclosure relates to a method and apparatus for processing a sidelink (SL) operation in a wireless communication system. An operating method of a first user equipment (UE) in a wireless communication system may include, when the first UE is in an radio resource control (RRC) connected state and is configured with discontinuous reception (DRX), monitoring a physical downlink control channel (PDCCH) transmitted from a base station (BS) during an active time associated with the DRX; detecting, based on the monitoring of the PDCCH, information associated with a SL resource allocated by the BS, identifying whether the SL resource is a resource for new transmission of a SL signal or a resource for re-transmission of the SL signal, when the SL resource is the resource for re-transmission of the SL signal, identifying whether a SL hybrid automatic repeat request (HARQ) feedback is enabled for a SL HARQ process of the first UE, when the SL HARQ feedback is enabled, receiving, from a second UE, SL HARQ feedback information about a SL signal transmitted from the first UE to the second UE, and reporting, to the BS, the received SL HARQ feedback information.
