Abstract: A transmitting device of the present invention submits, from a packet data convergence protocol (PDCP) entity configured with a PDCP duplication function, a PDCP protocol data unit (PDU) (duplicated PDCP PDU 1) to a lower layer and starts a prohibit timer for the duplicated PDCP PDU 1. The transmitting device submits, from the PDCP entity, the same PDCP PDU (duplicated PDCP PDU 2) to the lower layer if the prohibit timer expires. The transmitting device transmit the duplicated PDCP PDU 1 and the duplicated PDCP PDU 2.

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: upon transmitting the UL data based on a configured grant (CG) configuration related to a Hybrid-ARQ (HARQ) process, starting a first timer related to the HARQ process and a second timer related to the HARQ process; and performing retransmission of the UL data based on the HARQ process, wherein an UL resource on which the retransmission is performed is determined based on whether a UL resource of the CG configuration is configured or not between an expiration time point of the first timer and an expiration time point of the second timer.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing DRX operation in wireless communication system, the method comprising: generating a MAC PDU including an indicator indicating the MAC PDU is a last MAC PDU to be transmitted to an eNB if the generated MAC PDU is a last MAC PDU to be transmitted to the eNB; transmitting the MAC PDU including the indicator; and starting using a DRX cycle right after the UE considers that the transmission of MAC PDU is successful.

Abstract: In the present invention, a user equipment (UE) receives resource configuration information including information on a first radio resource not dedicated to the UE. The UE performs transmission of uplink data using the first radio resource. The UE transmits a request for radio resource dedicated to the UE for retransmission of the uplink data if the transmission of the uplink data using the first radio resource is not successful for a certain number of transmissions of the uplink data or for a certain period of time.

Abstract: The present invention relates to a wireless communication system and a method and a device for transmitting uplink data packet based on QoS framework in wireless communication system, the method comprising: receiving uplink (UL) packet with a first QoS flow ID from an upper layer; checking whether the first QoS flow ID is prohibited or not based on QoS flow prohibition information; and determining whether to transmit the UL packet according to result of checking; wherein the UL packet of the first QoS flow ID is not transmitted if the first QoS flow ID is prohibited; and wherein the UL packet with the first QoS flow ID is transmitted to a network via a DRB, if the first QoS flow is not prohibited. 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.

Abstract: A transmitting device generates a medium access control (MAC) protocol data unit (PDU), and transmits the MAC PDU. The transmitting device generates the MAC PDU such that the MAC PDU includes at least a MAC service data unit (SDU) and a first MAC subheader of the MAC SDU which is attached immediately after the end of the MAC SDU, or a MAC control element (CE) and a second MAC subheader of the MAC CE which is attached immediately after the end of the MAC CE.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling state variables of a PDCP entity in wireless communication system, the method comprising: delivering an PDCP SDU associated with a first COUNT to upper layer and starting, by the PDCP entity, a reordering timer, when an out-of-order PDCP PDU with the first COUNT value is received from lower layer; updating a value of a first state variable to the first COUNT value+1, when the reordering timer starts; and when the reordering timer expires, updating, by the PDCP entity, a value of a second state variable based on a second COUNT value of a first PDCP SDU which has not been delivered to upper layers, among PDCP SDUs with COUNT values which are equal to or larger than the first state variable.
