Abstract: 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.

Abstract: A method for processing downlink (DL) signals by a user equipment (UE) in a wireless communication system is disclosed. Especially, the UE is configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process. The method comprises steps of upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected, starting a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process, without transmitting the HARQ feedback; and monitoring subsequent PDCCHs related to retransmission of the DL HARQ process while the timer is running.

Abstract: The present invention relates to a method of performing a discontinuous reception (DRX) operation by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: monitoring a wake up-signal (WUS) periodically in WUS transmission opportunities; if the WUS is successfully detected in the WUS transmission opportunities and if the WUS indicates to wake up, monitoring a physical downlink control channel (PDCCH) during a first DRX ON duration; and if the WUS is not successfully detected in the WUS transmission opportunities, monitoring the PDCCH during a second DRX ON duration, wherein the second DRX ON duration is longer than the first DRX ON duration.

Abstract: The present invention relates to a method for performing uplink transmissions by a user equipment in a wireless communication system. In particular, the method includes the steps of: transmitting a data unit to a network using a configured uplink grant; receiving an uplink grant for retransmission of the data unit from the network; determining a retransmission timing using a parameter related to a retransmission delay; and retransmitting the data unit to the network using the uplink grant for retransmission on the determined retransmission timing. Especially, the configured uplink grant is shared by the user equipment and another user equipment, and the parameter indicates at least one instance of retransmission delay.

Abstract: A method for transmitting a medium access control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of receiving information about a first grant and a second grant; generating the MAC PDU for the first grant; storing the MAC PDU in a first Hybrid automatic repeat request (HARQ) buffer associated with the first grant and a second HARQ buffer associated with the second grant; performing listen before talk (LBT) procedure for the first grant and the second grant; and transmitting the MAC PDU on a grant for which the LBT succeeds firstly among the first grant and the second grant.

Abstract: The present invention relates to a method for performing uplink transmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: receiving a dynamic uplink grant for a HARQ process from a reception end; and performing an uplink transmission scheduled by the dynamic uplink grant, wherein at least one uplink transmission on at least one configured uplink grant for the HARQ process after receiving the dynamic uplink grant before performing the uplink transmission scheduled by the dynamic uplink grant is skipped.

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 MAC subheader. The MAC subheader includes a first indicator field regarding whether the MAC subheader include an RAP identity (ID) or not. The MAC subheader further includes a second indicator field regarding whether the MAC subheader includes a backoff indicator field or not, based on the first indicator field set to a value indicating that the MAC subheader does not include an RAP ID.
