Abstract: The present invention relates to a method for retransmitting a data unit by a user equipment in a wireless communication system. In particular, the method includes transmitting the data unit using one of multiple hybrid automatic repeat request (HARQ) processes on a first bandwidth part (BWP); identifying a failure of transmission of the data unit; selecting a second BWP on which a transmission opportunity corresponding to the one HARQ process is the closest from identifying the failure of the transmission, among two more BWPs; and re-transmitting the data unit using the one HARQ process on the second BWP.

Abstract: A method and apparatus for performing an uplink (UL) transmission with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a connection release message from a network in a first state. The connection release message includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams. The UE enters a second sate from the first state, selects a cell, and performs the UL transmission to the cell in the second state via the pre-allocated beams based on the pre-configured UL resource for UL transmission when a data is available for transmission. The first state may be a radio resource control (RRC) connected state, and the second state may be an RRC inactive state and/or an RRC idle state.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an adaptive bundling transmission in wireless communication system, the method comprising: generating a uplink (UL) data to be transmitted for an uplink grant of a Hybrid-ARQ (HARQ) process; performing a new HARQ transmission of the UL data with resetting a counter of the HARQ process, performing a HARQ retransmission of the UL data, if the new HARQ transmission of the UL data fails, wherein the counter is counted each time a HARQ transmission of the UL data fails, wherein if the counter is equal to or larger than a threshold, the HARQ retransmission of the UL data is performed with bundling transmission.

Abstract: In the present invention, if a transmitting device receives an activation command for a packet duplication function of a PDCP entity for a radio bearer (RB), the PDCP entity submits a PDCP protocol data unit (PDU) to each of multiple lower layer entities associated with the PDCP entity, and each of the multiple lower layer entities transmits the PDCP PDU. If the transmitting device receives a deactivation command for the packet duplication function, the PDCP entity submits the PDCP PDU to a single one of the multiple lower layer entities, and the single one of the multiple lower layer entities transmits the PDCP PDU.

Abstract: A user equipment (UE) determines whether a size of data available for transmission in a PDCP (Packet Data Convergence Protocol) entity of the UE, excluding a size of a PDCP Control PDU (Protocol Data Unit), exceeds a threshold value. Here, the PDCP Control PDU is predetermined to be transmitted through the first link of the bearer. The PDCP entity of the UE informs an indication on (a) the size of the data available for transmission, or (b) the size of the PDCP Control PDU, to a first entity of the UE for the first link based on the determination, and the first entity can transmit a buffer status report to the network based on the indication. Here, the size of the data available for transmission in the PDCP includes the size of the PDCP Data PDU and the size of the PDCP Control PDU.
