Abstract: A method for transmitting signals by a medium access control (MAC) entity of a transmission end in a wireless communication system is disclosed. The method includes steps of receiving a protocol data unit (PDU) from a Radio Link Control (RLC) layer; transmitting a signal including the PDU based on a specific coverage enhanced (CE) level to a network; when a transmission of the signal to a network is failed, determining whether a current CE level is changed or not from the specific CE level; if the current CE level is changed from the specific CE level, transmitting an indication requesting a retransmission of the PDU, to the RLC layer; receiving the PDU from the RLC layer; and transmitting a signal including the PDU based on the current CE level to the network.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting uplink data which is robust to collision on shared uplink resource in wireless communication system, the method comprising: checking whether uplink data is allowed to transmit on contention based resource or not, when the uplink data becomes available for transmission; and transmitting a buffer status reporting (BSR) on the contention based resource without any uplink data, if the uplink data is not allowed to transmit on the contention based resource.

Abstract: The present disclosure relates to backhaul status reporting in wireless communications. According to an embodiment of the present disclosure, a method performed by a network node in a wireless communication system comprises: monitoring backhaul links for multiple cell groups; receiving information indicating at least one cell group of which a backhaul status is to be reported among the multiple cell groups; and transmitting a message for reporting the backhaul status of the at least one cell group based on the information.

Abstract: The present invention relates to a method of transmitting a buffer status report (BSR) by an Integrated Access and Backhaul (IAB) node in a wireless communication system. In particular, the method includes the steps of: generating the BSR; and transmitting the BSR to the network, wherein the BSR includes data volume of the IAB node determined by considering data volume of at least one RLC (Radio Link Control) layer entity of the IAB node and data volume of an adaptation layer of the IAB 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: 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.
