Abstract: In the present disclosure, a UE receives configuration information regarding a measurement gap (MG); transmits a MG skip indication associated with the MG; and transmits uplink signals during the MG.

Abstract: The present invention relates to a method of generating a Medium Access Control Protocol Data Unit (MAC PDU) by a UE in a wireless communication system. In particular, the method includes the steps of: receiving configuration information related to multiple logical channels; receiving information related to multiple configured grants; generating the MAC PDU by performing a Logical Channel Prioritization (LCP) for the multiple logical channels based on a PBR value related to an activated grant; and transmitting the MAC PDU to a network.

Abstract: The present invention relates to a method of transmitting a buffer status report (BSR) by a wireless node in a wireless communication system. In particular, the method includes the steps of: receiving first logical channel group (LCG) configuration information including identities of LCGs from a network; generating the BSR including a LCG field; and transmitting the BSR to the network, wherein a length of the LCG field is configured according to a highest value of the identities of LCGs.

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: 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: The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: based on the UE transmitting the UL data on a first UL resource of a configured grant (CG) con-figuration based on a Hybrid-ARQ (HARQ) process, starting a CG retransmission timer for the HARQ process and a CG timer for the HARQ process; based on a second UL resource of the CG configuration not being configured between an expiration time point of the CG retransmission timer and an expected expiration time point of the CG timer, stopping the CG timer upon expiration of the CG retransmission timer; and performing retransmission of the UL data based on the HARQ process after the expected expiration time point of the CG timer.

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: Method and apparatus for a user equipment (UE) supporting dual connectivity (DC) with a master node and a secondary node are disclosed. According to these, the UE receives first configuration information from the master node and second configuration information from the secondary node. The UE applies the first configuration information first. And, the UE transmits a new configuration request message to the secondary node, if the UE cannot apply the second configuration information after applying the first configuration information.
