Abstract: 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.

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 of performing operations of an Integrated Access and Backhaul (IAB) node in a wireless communication system. In particular, the method includes the steps of: receiving, from a first parent IAB node, a Radio Resource Control (RRC) message to be forwarded to a child IAB node; and forwarding the RRC message to the child IAB node, wherein, based on a connection attempt to a second parent IAB node being failed, a discard indication is transmitted to the child IAB node, wherein the discard indication indicates that the RRC message is to be discarded by the child IAB node.

Abstract: The present invention relates to a method of transmitting a buffer status report (BSR) by a wireless node in a wireless communication system. In particular, the method includes the steps of: receiving first logical channel group (LCG) configuration information including identities of LCGs from a network; generating the BSR including a LCG field; and transmitting the BSR to the network, wherein a length of the LCG field is configured according to a highest value of the identities of LCGs.

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 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: Provided are a method for transmitting a message by a user equipment (UE) in a wireless communication, and an apparatus supporting the same. The method may include: initiating early data transmission; receiving a random access response message including an uplink grant, from a base station (BS); based on the uplink grant, determining whether or not to transmit a first message related to the early data transmission to the BS, in response to the random access response message; and after determining to transmit the first message related to the early data transmission, resuming radio bearers for the early data transmission.
