Abstract: The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity; determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.

Abstract: The present invention relates to a method of transmitting a status report by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving information about whether a Packet Data Convergence Protocol (PDCP) duplication for downlink is activated or not; receiving at least one data unit from a network; determining whether the status report related to the at least one data unit is triggered or not; based on whether the PDCP duplication for the downlink is activated or not; and transmitting the triggered status report related to the at least one data unit, wherein, based on the PDCP duplication for the downlink being activated, the status report related to the at least one data unit is not triggered.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling state variables of a PDCP entity in wireless communication system, the method comprising: delivering an PDCP SDU associated with a first COUNT to upper layer and starting, by the PDCP entity, a reordering timer, when an out-of-order PDCP PDU with the first COUNT value is received from lower layer; updating a value of a first state variable to the first COUNT value +1, when the reordering timer starts; and when the reordering timer expires, updating, by the PDCP entity, a value of a second state variable based on a second COUNT value of a first PDCP SDU which has not been delivered to upper layers, among PDCP SDUs with COUNT values which are equal to or larger than the first state variable.

Abstract: The present invention relates to a method of transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system, wherein the UE is connected to a first network. In particular, the method includes the steps of: performing a random access procedure with a second network; and based on the random access procedure being successfully performed, discarding packets which are stored in a buffer for transmission to the first network.

Abstract: The present invention relates to a method of transmitting data units by a Radio Link Control (RLC) entity of a user equipment (UE) in a Radio Resource Control (RRC) INACTIVE state in a wireless communication system. Especially, the method includes the steps of transmitting at least one first data unit without the poll in the RRC INACTIVE state to a peer RLC entity; based on a number of the at least one first data unit without the poll being equal to or greater than a threshold value, shifting to a RRC CONNECTED state; transmitting a second data unit with the poll in the RRC CONNECTED state to the peer RLC entity; and receiving a status report for the at least one first data unit without the poll and the second data unit with the poll from the peer RLC entity.

Abstract: The present invention relates to a method of performing a handover procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of initializing state variables for at least one radio bearer (RB) based on receiving a handover command from a source network; performing the handover procedure to a target network while maintaining the connection with the source network; based on detecting a handover failure to the target network, reverting back the state variables for the at respectively, and applying the first network configuration least one RB to the state variables used in the source network; and reporting information related to the handover failure to the source network.

Abstract: A method for transmitting a packet by a Packet Data Convergence Protocol (PDCP) entity of a user equipment in a wireless communication system is disclosed. The method comprises delivering a packet to a first Radio Link Control (RLC) entity; and when a radio link failure (RLF) related to the first RLC entity is detected, retransmitting the packet through a second RLC entity if acknowledgement information of the packet is not received from the first RLC entity.
