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 performing a Short Data Transmission (SDT) procedure for transmitting a data unit in the RRC INACTIVE state; based on a failure of the SDT procedure being detected, determining whether a radio bearer (RB) of at least one logical channel related to the data unit is Acknowledged Mode (AM) RB or not; based on the RB not being the AM RB, discarding the data unit; and based on the RB being the AM RB, transmitting a RRC message to the network for requesting RRC connection resumption and performing the retransmission of the data unit in a RRC CONNECTED state.

Abstract: The present disclosure relates to a method of performing data transmission by a user equipment (UE) in a wireless communication system. Especially, the method includes the 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 second resources and a threshold; and if a time gap between a current time and a first resource is smaller than the threshold, performing the data transmission in the RRC INACTIVE state based on the first resource with ignoring at least one of the second resources which is located earlier than the first resource.

Abstract: A method for transmitting a truncated Medium Access Control (MAC) Control Element (CE) report by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of triggering transmissions of one or more MAC CEs; receiving an uplink grant from a network; based on the uplink grant not accommodating the one or more MAC CEs, generating a MAC Protocol Data Unit (PDU) including a truncated MAC CE report; transmitting the MAC PDU to the network, wherein the truncated MAC CE report includes information related to at least one MAC CE which is triggered but not included or partially included in the MAC PDU among the one or more MAC CEs.

Abstract: A method for transmitting a configured grant (CG) confirmation message by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of receiving information related a CG from a network; triggering a CG confirmation upon receiving a CG activation command from the network, wherein, based on data to be transmitted on a new transmission opportunity being available, the triggered CG confirmation is canceled; and based on there being a CG confirmation not canceled, transmitting the CG confirmation message for the triggered CG confirmation on the new transmission opportunity.

Abstract: A method for receiving downlink data by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of configuring at least one Semi Persistent Scheduling (SPS) configuration comprising a plurality of SPS occasions; starting a SPS monitoring timer; monitoring a downlink assignment on the plurality of SPS occasions during the SPS monitoring timer is running; based on detecting the downlink assignment on one SPS occasion of the plurality of SPS occasions, receiving the downlink data based on the downlink assignment on the one SPS occasion and stopping the SPS monitoring timer, wherein the SPS monitoring timer is re-started at a time point to be expected an expiration of the SPS monitoring timer.

Abstract: The present disclosure relates to a method for performing a configured grant (CG) based small data transmission (SDT) in a wireless communication system. In particular, the method includes the steps of: storing a reference Reference Signal Received Power (RSRP) upon a reception of Configured Grant based Small Data Transmission (CG-SDT) configuration via a Radio Resource Control (RRC) release message; measuring a current RSRP based on a SDT procedure being initiated; and based on a difference between the current RSRP and the reference RSRP being less than or equal to a threshold value, perform a CG-SDT procedure based on the CG-SDT configuration.

Abstract: A user equipment (UE) can perform dual registration with different radio access technology (RAT) system. The UE registers with a core network of a second system independent of a first system while maintaining registration with a core network of the first system. The UE transmits, to the second system, first information indicating that the UE has the registration with the first system when connecting to the second system. One of the first and second systems may be a LTE system using a first radio access technology (RAT), and the other one may be new RAT system using a second RAT different from the first RAT.

Abstract: Provided is a method and device for selectively transmitting a secondary cell group (SCG) failure information message to one of a master node (MN) and a secondary node (SN) in a wireless communication system. A user equipment (UE) detects a failure related to an SCG, and selectively transmits an SCG failure information message to one of an MN and an SN according to a reason for the failure related to the SCG. For example, if the reason for the failure related to the SCG is associated with the size of a hybrid automatic repeat request (HARQ) buffer, the UE ma transmit the SCG failure information message to the SN.
