    摘要: 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.

    摘要: The present invention relates to a method of performing a random access to a base station by a user equipment (UE) in a wireless communication system. In particular, the method includes transmitting a random access preamble and a payload including a common control channel (CCCH) service data unit (SDU) to the network; and receiving a medium access control (MAC) protocol data unit (PDU) in response to the random access preamble and the payload, wherein the MAC PDU includes a contention resolution identifier (CRID) and an indicator indicating a presence of a signaling radio bearer (SRB) radio resource control (RRC) message corresponding to the CRID in the MAC PDU.

    摘要: A method and apparatus for completion mechanism for transmission using preconfigured uplink resource (PUR) in a wireless communication system is provided. While in a radio resource control (RRC) idle state and/or an RRC inactive state, a wireless device configured to operate in a wireless communication system i) performs uplink (UL) data transmission using a preconfigured uplink resource (PUR) to a network, ii) attempts to acquire downlink (DL) information on a physical downlink shared channel (PDSCH) from the network, and iii) based on the DL information including only timing advance command (TAC) media access control (MAC) control element (CE), considers that the UL data transmission using the PUR is successful.

    摘要: 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. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

    摘要: 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.
