    Abstract: The present disclosure relates to a method for 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 activation command for a configured uplink grant; based on there being a pending protocol data unit (PDU) associated with an identified Hybrid Automatic Repeat Request (HARQ) process, checking whether a configured grant confirmation medium access control (MAC) control element (CE) related to the configured grant activation command has been transmitted or not; and based on the configured grant confirmation MAC CE having been transmitted, transmitting the pending PDU.

    Abstract: The present disclosure relates to a method for performing an uplink (UL) transmission by user equipment in a wireless communication system. In particular, the method includes the steps of: receiving an UL grant associated with a first Hybrid Automatic Repeat Request (HARQ) process from a gNB; selecting a second HARQ process among the first HARQ process and the second HARQ process, when there is a first medium access control (MAC) protocol data unit (PDU) which is associated with the first HARQ process and is a pending MAC PDU; generating a second MAC PDU associated with the second HARQ process; and performing the uplink transmission of the second MAC PDU with an identifier (ID) of the second HARQ process.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a LCP procedure in wireless communication system, the method comprising: receiving multiple uplink (UL) grants, in a state that the UE is configured to one or more logical channels, each of the one or more logical channels being associated with a respective numerology set; wherein each of the multiple UL grants includes information for an associated numerology set; and performing a logical channel prioritization (LCP) procedure using the multiple UL grants in ascending order of a number of logical channels associated with a numerology set for each UL grant.

    Abstract: In the present disclosure, a transmitting device transmits a first message comprising i) a first random access preamble with a first random access preamble identifier (RAPID) and ii) a first uplink payload; receives a random access response (RAR) medium access control (MAC) protocol data unit (PDU) including i) a first field set to represent presence of one or more RAPIDs and ii) the one or more RAPIDs; determines whether both of the first RAP and the first payload is successfully transmitted, based on whether the one or more RAPIDs include the first RAPID; and monitors a second message related to the first message based on determining that both of the first RAP and the first payload is successfully transmitted.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of HARQ process IDs with uplink skipping in wireless communication system, the method comprising: receiving a HARQ process ID set including a plurality of HARQ process IDs in a sequential order from a network; receiving a set of uplink resources from the network; transmitting a first data on a first uplink resource with a first HARQ process ID among the plurality of HARQ process IDs; skipping one or more transmissions on one or more uplink resources; transmitting a second data on a second uplink resource with a second HARQ process ID among the plurality of HARQ process IDs, wherein the second HARQ process ID is the very next ID of the first HARQ process ID according to the sequential order in the HARQ process ID set.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling pre-configured UL resources based on LBT procedure in wireless communication system, the method comprising: receiving information for UL resource configuration from a network, in a state that the UE is configured with at least one serving cell operating in an unlicensed spectrum; performing LBT operation for transmission of uplink data by using the UL resource, wherein the UE starts counting a number of failures of the LBT operation once the UE is not allowed to use the UL resource for transmission of uplink data during the LBT operation, and when the number of failures of the LBT operation reaches to the maximum number of LBT failure, stopping using the UL resource.
