Abstract: The present invention relates to a method of transmitting data units by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of transmitting at least first one data unit in a Radio Resource Control (RRC) CONNECTED state with a sequence number for the RRC CONNECTED state; receiving a RRC INACTIVE transition command with an initial sequence number for data transmission in a RRC INACTIVE state; setting a sequence number for the RRC INACTIVE state as the initial sequence number; and transmitting at least one second data unit in the RRC INACTIVE state with the sequence number for the RRC INACTIVE state, wherein the sequence number for the RRC INACTIVE state is incremented by 1 for every second data unit.

Abstract: In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a common control channel (CCCH) service data unit (SDU) on a physical uplink channel (PUSCH). The UE receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU may include a MAC PDU associated with a contention resolution identity (CRID) in the MAC PDU. The UE determines whether a MAC SDU is present or not in the MAC PDU, based on the MAC SDU indicator associated with a CRID in the MAC PDU in a state in which the CRID matches the CCCH SDU.

Abstract: In the present invention, a user equipment (UE) receives an UL grant that can be used while the UE is not in RRC_CONNECTED state. If the UE receives a message indicating to leave RRC_CONNECTED state, the UE starts a time alignment timer (I-TAT) when the UE leaves RRC_CONNECTED state. The UE transmits UL data using the UL grant if the UL data becomes available for transmission when the UE is not in RRC_CONNECTED state and if the I-TAT is running.

Abstract: The present invention relates to a method of performing uplink transmission by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a configured grant (CG) activation command for a configured uplink grant; based on a size of the configured uplink grant not matching with a size of a pending protocol data unit (PDU) associated with an identified HARQ process, flushing a Hybrid Automatic Repeat Request (HARQ) buffer of the identified HARQ process; and transmitting a CG confirmation medium access control (MAC) control element (CE) using the identified HARQ process.

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 scheduling request (SR) by a user equipment (UE) in a wireless communication system, wherein the UE is connected to a first network. In particular, the method includes the steps of: performing a random access procedure with a second network; and based on the random access procedure being successfully performed, discarding packets which are stored in a buffer for transmission to the first network.

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: In the present disclosure, a transmitting device receives zero header information from a receiving device, generates a MAC PDU based on the zero header information, and transmits the MAC PDU. The zero header information may include information regarding a logical channel or MAC control element (CE). The MAC PDU may include a MAC subPDU containing data of the logical channel or the MAC CE without corresponding MAC subheader.

Abstract: A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.
