Abstract: A method for transmitting a data unit by an Integrated Access and Backhaul (IAB) node in a wireless communication system is disclosed. The method comprises steps of receiving, from a network, backhaul (BH) configuration including first information about first bearers associated with a parent node and second information about second bearers associated with a child node, wherein each of the first bearers is configured with a BH identifier belonging to a first BH identifier set, wherein each of the second bearers is configured with a BH identifier belonging to a second BH identifier set; receiving the data unit from the parent node via one of the first bearers; and transmitting the data unit to the child node via one of the second bearers.

Abstract: The present invention relates to a method for performing retransmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: re-transmitting a data unit to a reception end; and increasing a retransmission counter associated with the data unit, when the retransmission counter associated with the data unit reaches to a max value, reporting a max retransmission indication to an upper layer and setting the retransmission counter associated with the data unit to zero.

Abstract: A radio link control (RLC) entity of a transmitting device receives a first RLC service data unit (SDU) from an upper layer of the transmitting device. If the RLC entity receives, from the upper layer, a discard indication to discard the first RLC SDU, the RLC entity checks whether the first RLC SDU has been submitted to a lower layer of the transmitting device. The RLC entity discards the first RLC SDU if neither the first RLC SDU nor a segment of the first RLC SDU has been submitted to the lower layer.

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.
