Abstract: In the present invention, a UE configured with a SPS resource which occurs periodically for a predetermined time duration transmits indication information using the last SPS resource which occurs last in the predetermined time duration, if the last SPS resource is not sufficient to accommodate uplink data available for transmission. The indication information informs a network that there is uplink data remaining after the UE performs uplink data transmission on the last SPS resource.

Abstract: The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.

Abstract: A method of performing, by a user equipment (UE), wireless communication using a serving cell in a wireless communication system is provided. The method includes: starting a deactivation timer associated with the serving cell, the deactivation timer relating to a duration of time after which the serving cell is deactivated; determining whether there is an uplink (UL) grant or a downlink (DL) assignment for the serving cell in a time unit; based on a determination that there is an UL grant or a DL assignment, determining whether a data unit is transmitted on the UL grant or is received on the DL assignment; based on a determination that the data unit is transmitted on the UL grant or is received on the DL assignment: restarting the deactivation timer associated with the serving cell; and transmitting the data unit on the UL grant or receiving the data unit on the DL assignment.

Abstract: The present disclosure relates to a method of performing operations for a User Equipment (UE) in a wireless communication system. In particular, the method includes configuring a Quality of Service (QOS) flow and at least two Sub-QoS flows associated with the QoS flow, wherein a first Sub-QoS flow of the at least two Sub-QoS flows is associated with a first data type and is mapped to a first data radio bearer (DRB), wherein a second Sub-QoS flow of the at least two Sub-QoS flows is associated with a second data type and is mapped to a second DRB, receiving an uplink data unit from an upper layer; and based on one of the first and second data types to which the uplink data unit belongs, submitting the uplink data unit to one of the first and second DRBs to which Sub-QoS flow associated with corresponding data type is mapped.

Abstract: The present disclosure relates to a method of transmitting a packet by an integrated access and backhaul (IAB) node in a wireless communication system. In particular, the method includes the steps of: receiving the packet from a child node; based on the packet having a separation indication, generating a radio resource control (RRC) message including the packet and transmitting the RRC message to a first parent node which is connected with a donor node directly; and based on the packet not having the separation indication, transmitting the packet with routing information related to the donor node to a second parent node which is connected with the donor node through a third parent node.

Abstract: The present disclosure relates to a method of transmitting a packet by an Integrated Access and Backhaul (IAB) node in a wireless communication system. In particular, the method includes the steps of: receiving, from a first node, an indication indicating that a congestion problem occurs between the first node and a second node; if the packet is to be transmitted to other node via the first node, transmitting the packet to the first node; and if the packet is to be transmitted to the second node via the first node, transmitting the packet to a third node.

Abstract: The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: based on the UE transmitting the UL data on a first UL resource of a configured grant (CG) con-figuration based on a Hybrid-ARQ (HARQ) process, starting a CG retransmission timer for the HARQ process and a CG timer for the HARQ process; based on a second UL resource of the CG configuration not being configured between an expiration time point of the CG retransmission timer and an expected expiration time point of the CG timer, stopping the CG timer upon expiration of the CG retransmission timer; and performing retransmission of the UL data based on the HARQ process after the expected expiration time point of the CG timer.

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.
