Abstract: The present invention relates to a method of transmitting a data unit by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of configuring a first pre-configured uplink (UL) resources (PUR) group and a second PUR group, wherein the first PUR group is used for data transmission not requiring the network feedback and the second PUR group is used for data transmission requiring the network feedback; generating the data unit to be transmitted to a network; selecting one of the first PUR group and the second PUR group based on whether a transmission of the data unit requires a feedback response of the data unit or not; selecting one of PURs belonging to the selected PUR group; and transmitting the data unit to the network on a UL resource belonging to the selected PUR.

Abstract: The present invention relates to a method of transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving an uplink shared channel (UL-SCH) resource; based on the UL-SCH resource being overlapped with another resource and the UL-SCH resource being deprioritized, triggering an SR for informing that the UL-SCH resource is deprioritized while having data available for transmission on the UL-SCH resource; and transmitting the SR to a network.

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 monitoring a Physical Downlink Control Channel (PDCCH) by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: monitoring the PDCCH discontinuously in transmission opportunities according to discontinuous reception (DRX) configuration; based on first downlink (DL) buffer status information indicating that there is DL data waiting for transmission being received from a network, monitoring the PDCCH continuously in all of the transmission opportunities with disabling the DRX configuration; and based on second DL buffer status information indicating that there is no more DL data waiting for the transmission being received from the network, monitoring the PDCCH discontinuously in the transmission opportunities according to the DRX configuration.

Abstract: A method for performing data transmission by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of receiving a message indicating a change of a Radio resource control (RRC) state from a RRC CONNECTED state to a RRC INACTIVE state, wherein the message includes information related to a configured grant (CG) and a threshold; if a time gap between a current time and an uplink grant occasion associated with the configured grant is larger than or equal to the threshold, triggering a random access (RA) procedure for the data transmission; and performing the data transmission based on the RA procedure in the RRC INACTIVE state, wherein, if the time gap is smaller than the threshold, the data transmission is performed based on the uplink grant occasion associated with the configured grant.
