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 wireless communication system. More specifically, the present invention relates to a method and a device for handling for Bandwidth Part operation in wireless communication system, the method comprising: starting a timer related to a downlink (DL) bandwidth part (BWP), when an active BWP for a serving cell is switched to the DL BWP; wherein DL semi-persistent scheduling (SPS) resources are configured on the DL BWP and uplink (UL) SPS resources are configured on a UL BWP related with the DL BWP; transmitting UL data on one of the UL SPS resources or receiving DL data on one of the DL SPS resources; and restarting the timer related to the DL BWP when the UL data is transmitted on the UL SPS resource or the DL data is received in the DL SPS resource.

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: 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.
