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 for managing uplink transmission resources by considering processing time of a data unit in a wireless communication system. In particular, the method includes the steps of: generating a data unit; based on the data unit not being able to be transmitted on a configured grant (CG), transmitting a message for requesting a dynamic grant on the CG; receiving the dynamic grant in response to the message; and transmitting the data unit on the dynamic grant.

Abstract: The present disclosure relates to a method for transmitting a data unit on uplink transmission resources based on processing time of the data unit in a wireless communication system. In particular, the method includes the steps of: configuring a first configured grant (CG) configuration and a scheduling request (SR) configuration related to the CG configuration, wherein the first CG configuration comprises first CG grants and the SR configuration comprises SR resources related to the CG grants; receiving a data unit from an upper layer; determining whether the data unit can be transmitted on one of the first CG grants of the first CG configuration or not; based on it being determined that the data unit cannot be transmitted on the one first CG grant, transmitting a SR message on a SR resource related to the CG grant; receiving a dynamic uplink grant in response to the SR message; and transmitting the data unit on the dynamic uplink grant.

Abstract: The present disclosure relates to a method of transmitting a control message by a first node in a wireless communication system. In particular, the method includes the steps of: configuring at least two service radio bearers (SRBs) for transmitting the control message from the first node to a third node; receiving the control message from a User Equipment (UE) operated by the first node or from a second node connected with the first node; and transmitting the control message through one SRB of the at least two SRBs to the third node, wherein the one SRB through which the control message is transmitted is determined among the at least two SRBs based on whether the control message is received from the UE or the second node

Abstract: An Integrated Access and Backhaul (IAB) node configured with a first Backhaul Adaptation Protocol (BAP) address related to a first donor IAB node and a second BAP address related to a second donor IAB node in a wireless communication system. Techniques include receiving a packet including a destination BAP address and a path identifier (ID). Based on the packet being received through the second link and the destination BAP address not matching the second BAP address, determining whether the destination BAP address and the path ID of the packet match at least one entry of a configured rewriting table. Based on the destination BAP address and the path ID of the packet matching the at least one entry, rewriting a header of the packet by setting the destination BAP address and the path ID according to the at least one entry, and transmitting the packet to a next hop node.

Abstract: The present disclosure relates to a routing path switching in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving a configuration for a first routing identity (ID) and a second routing ID, wherein the first routing ID is related to a first routing path towards a destination node, and the second routing ID is related to a second routing path towards the destination node; transmitting, to the destination node, a first protocol data unit (PDU) via the first routing path related to the first routing ID; and based on that a condition to switch a routing path is satisfied: constructing a second PDU so that a header of the second PDU includes information for a routing path switch to the second routing path; and transmitting, to the destination node, the second PDU including the header via the second routing path related to the second routing ID.

Abstract: The present disclosure relates to a method of processing signals by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a data signal including a data unit for a multicast/broadcast service (MBS) based on a control signal addressed with a Group-Radio Network Temporary Identifier (G-RNTI) from a network; identifying a logical channel for the MBS among two or more logical channels, based on the G-RNTI and a logical channel identifier; and transferring the data unit for the MBS to the identified logical channel.
