    Abstract: The present invention relates to a method for processing signals by a node in a wireless communication system. In particular, the method includes receiving a radio bearer (RB) configuration message from a network; and configuring a radio bearer between a radio link control (RLC) entity of the node and a peer RLC entity using the RB configuration message, wherein the RB configuration message includes information about that the peer RLC entity operates with a different RLC mode from a RLC entity of the node.

    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 handling data lossless in a UM RLC entity in wireless communication system, the method comprising: receiving a Radio Resource Control (RRC) message for releasing or reestablishing of a Unacknowledged Mode (UM) Radio Link Control (RLC) entity; transmitting, by the UM RLC entity to a Packet Data Convergence Protocol (PDCP) entity associated with the UM RLC entity, information for transmission status of RLC Service Data Units (SDUs) stored in the UM RLC entity; and discarding all RLC SDUs and Unacknowledged Mode Data (UMD) Protocol Data Units (PDUs) stored in the UM RLC entity.

    Abstract: The present disclosure relates to a method of performing operations by PDCP entity of a User Equipment (UE). In particular, the method includes performing a transmission of a first PDCP SDU compressed based on a first UDC context, wherein the first UDC context is updated based on the first PDCP SDU; receiving a successful delivery confirmation of the first PDCP SDU, wherein a second UDC context is updated based on the first PDCP SDU; performing a transmission of a second PDCP SDU compressed based on the first UDC context, wherein the first UDC context is updated based on the second PDCP SDU; based on an indication for re-establishment being received before receiving a successful delivery confirmation of the second PDCP SDU, overriding the second UDC context to the first UDC context and performing a retransmission of the second PDCP SDU compressed based on the overridden first UDC context.

    Abstract: The present disclosure relates to a method of performing a frame level discard operation by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a first data unit associated with a frame from an upper layer, wherein a discard timer is started upon receiving the first data unit; and receiving a second data unit associated with the frame from the upper layer; transmitting the first data unit and the second data unit while the discard timer is running, wherein, based on the discard timer being expired, the first data units and the second data unit are discarded

    Abstract: The present invention relates to a method of transmitting uplink data by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving information about first uplink configured grants (CGs) and second uplink CGs from a network; triggering a Buffer Status Report (BSR); and if at least one of the second uplink CGs can accommodate all of data to be transmitted, transmitting the data to the network on the at least one second uplink CG without transmitting the BSR on the first uplink CG, wherein, if the at least one second uplink CG can accommodate the data partially, the BSR is transmitted to the network on the first uplink CG without transmitting the data on the at least one second uplink CG.
