Abstract: The present disclosure relates to a method of performing data transmissions in a Radio Resource Control (RRC) INACTIVE state by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of generating at least one Small Data Transmission (SDT) data unit that can be transmitted in RRC INACTIVE state; triggering a SDT procedure for transmitting the at least one SDT data unit in RRC INACTIVE state; generating a non-SDT data unit that cannot be transmitted in RRC_INACTIVE during the SDT procedure; generating an indication message informing that there is the non-SDT data unit, based on an uplink grant related to the SDT procedure for transmitting the indication message being available; and transmitting the indication message via a Dedicated Control Channel (DCCH) during the SDT procedure to a network.

Abstract: The present invention relates to a method for transmitting a medium access control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of generating the MAC PDU; and based on a listen before talk (LBT) succeeding, transmitting the MAC PDU on an uplink resource using a Hybrid automatic repeat request (HARQ) process; wherein, based on the MAC PDU including user data, a configured grant timer (CGT) and a configured grant retransmission timer (CGRT) for the HARQ process are started, and a status of the HARQ process is set to not pending, wherein, based on the MAC PDU not including the user data and being multiplexed with uplink control information (UCI), the CGT and the CGRT for the HARQ process are not started, and the status of the HARQ process is set to not pending.

Abstract: The present invention relates to a method of transmitting uplink data by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving information about first uplink configured grants (CGs) and second uplink CGs from a network; triggering a Buffer Status Report (BSR); and if at least one of the second uplink CGs can accommodate all of data to be transmitted, transmitting the data to the network on the at least one second uplink CG without transmitting the BSR on the first uplink CG, wherein, if the at least one second uplink CG can accommodate the data partially, the BSR is transmitted to the network on the first uplink CG without transmitting the data on the at least one second uplink CG.

Abstract: In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a control channel (CCCH) service data unit (SDU) on a physical uplink shared channel (PUSCH); and receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU includes a first part, and a second part after the first part. The first part includes multiple UE contention resolution identities (UE CRIDs).

Abstract: The present disclosure relates to a method for transmitting a protocol data unit (PDU) by a transmission end in a wireless communication system. In particular, the method includes receiving an uplink (UL) grant from a network; when the UL grant can accommodate all of pending data for a first logical channel but is not sufficient to additionally accommodate a buffer status report (BSR), including the pending data for the first logical channel to the PDU with canceling the BSR; and transmitting the PDU to the network, wherein the UL grant cannot additionally accommodate all of pending data for a second logical channel

Abstract: In the present disclosure, a first node performs buffer status reporting including information regarding a total amount of UL data. The first node determines the total amount of UL data for the buffer status reporting based on an amount of UL data for which the UL resources are actually allocated to the second node by the first node.
