    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.
