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: 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: In the present invention, a UE configured with a SPS resource which occurs periodically for a predetermined time duration transmits indication information using the last SPS resource which occurs last in the predetermined time duration, if the last SPS resource is not sufficient to accommodate uplink data available for transmission. The indication information informs a network that there is uplink data remaining after the UE performs uplink data transmission on the last SPS resource.

Abstract: A method and apparatus for performing operations in a wireless communication system disclosed herein may measure a RSRP of a downlink pathloss reference based on the preamble transmission counter being equal to or higher than a first threshold. And the second preamble is transmitted on a second random access occasion related to the MSG3 repetition based on the RSRP being lower than a second threshold.

Abstract: The present disclosure relates to a method of transmitting a random access preamble by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving multiple synchronization signal blocks (SSBs) from a network, wherein the multiple SSBs comprise one or more SSBs associated with Msg3 physical uplink shared channel (PUSCH) repetition; based on reception powers of all of SSBs being less than a first threshold, selecting one SSB among the one or more SSBs associated with Msg3 PUSCH repetition; based on reception power of any one of SSBs being equal to or greater than the first threshold, selecting any SSB not associated with Msg3 PUSCH repetition among the multiple SSBs; and transmitting the random access preamble based on a random access resource related to the selected SSB.

Abstract: The present invention 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 the packet from a child node; based on the packet having a separation indication, generating a radio resource control (RRC) message including the packet and transmitting the RRC message to a first parent node which is connected with a donor node directly; and based on the packet not having the separation indication, transmitting the packet with routing information related to the donor node to a second parent node which is connected with the donor node through a third parent node.

Abstract: The present invention relates to a method of transmitting buffer status report (BSR) by a node in a wireless communication system. In particular, the method includes the steps of: transmitting, to a parent node, a first BSR with starting a timer before receiving data from a child node; triggering a second BSR based on receiving the data from the child node; and based on the data not being transmitted to the parent node until expiration of the timer, transmitting, to the parent node, a scheduling request (SR) for transmission of the second BSR, wherein, based on the data being transmitted to the parent node before the expiration of the timer, the timer is stopped and the second BSR is canceled.

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: If there are missing RLC SDU(s) and/or missing RLC SDU segment(s), a receiving device transmits a STATUS PDU to a transmitting device in order to inform the missing RLC SDU(s) and/or missing RLC SDU segment(s). If there are multiple RLC SDU segments belonging to one RLC SDU, the STATUS PDU of the present invention one sequence number (SN) for the multiple missing RLC SDU segments, which is the same as a SN of the RLC SDU, and location information on each of the multiple missing RLC SDU segments within the RLC SDU.
