Abstract: A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

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 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 wireless communication system. More specifically, the present invention relates to a method and a device for handling pre-configured UL resources based on LBT procedure in wireless communication system, the method comprising: receiving information for UL resource configuration from a network, in a state that the UE is configured with at least one serving cell operating in an unlicensed spectrum; performing LBT operation for transmission of uplink data by using the UL resource, wherein the UE starts counting a number of failures of the LBT operation once the UE is not allowed to use the UL resource for transmission of uplink data during the LBT operation, and when the number of failures of the LBT operation reaches to the maximum number of LBT failure, stopping using the UL 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.
