Abstract: The present invention relates to a method of processing a data unit by a Service Data Adaptation Protocol (SDAP) entity of a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a SDAP Service Data Unit (SDU) from an upper layer; generating a SDAP protocol data unit (PDU) including a SDAP header and the SDAP SDU; and submitting the SDAP PDU to a lower layer, wherein the SDAP header includes a Quality of Service (QoS) Flow Identifier (QFI) field, wherein, based on that the QFI field has a specific value, the SDAP header further includes an extended QFI field having a value corresponding to the SDAP SDU.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an adaptive bundling transmission in wireless communication system, the method comprising: generating a uplink (UL) data to be transmitted for an uplink grant of a Hybrid-ARQ (HARQ) process; performing a new HARQ transmission of the UL data with resetting a counter of the HARQ process, performing a HARQ retransmission of the UL data, if the new HARQ transmission of the UL data fails, wherein the counter is counted each time a HARQ transmission of the UL data fails, wherein if the counter is equal to or larger than a threshold, the HARQ retransmission of the UL data is performed with bundling transmission.

Abstract: Provided are a method for performing, by a user equipment (UE), transmission via only a primary path in a wireless communication system, and an apparatus supporting the same. The method may include: configuring a split bearer, which has multiple L2 entities for both a master cell group (MCG) and a secondary cell group (SCG); when the UE transits from a first state to a second state, reconfiguring the primary path of the split bearer autonomously; and performing the transmission via only the primary path of the split bearer, wherein the primary path is related to an L2 entity for the MCG.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting lossless data packet based on QoS framework in wireless communication system, the method comprising: starting a timer for a first QoS flow when a DRB which is mapped to the first QoS flow is changed from a first DRB to a second DRB; delivering packets of the first QoS flow received from the first DRB to an upper layer while the timer is running; when the timer expires, starting to deliver the packets of the first QoS flow received from the second DRB while stopping the delivering packets of the first QoS flow received from the first DRB.

Abstract: A method and apparatus for performing a cell selection triggered by a lower layer signaling in a wireless communication system is provided. A first node receives information for triggering a connection reestablishment, i.e. the lower layer signaling, from a second node. The first node deprioritizes a serving cell based on the information for the triggering the connection reestablishment, and after deprioritizing the serving cell, selects a cell other than the serving cell. The first node performs uplink (UL) transmission on the selected cell for the connection reestablishment.
