Abstract: A method for transmitting signals by a UE configured with two or more transmission paths of one radio bearer (RB) in a wireless communication system is disclosed. The method comprises detecting a stuck problem in one transmission path of the two or more transmission paths; transmitting an indicator related to the stuck problem to a network; and resetting a protocol entity of the transmission path having the stuck problem, wherein the stuck problem comprises a difference between the sequence number (SN) of the data unit transmitted by the transmission path having the stuck problem and the SN of the data unit transmitted by another transmission path being larger than a threshold.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a scheduling request in a wireless communication system, the method comprising: receiving mapping information of SR resource sets and logical channels from an eNB, wherein one of the SR resource sets is a set of uplink resources that is used for transmitting SR; triggering a SR by a data of a logical channel; and transmitting the triggered SR on the SR resource set associated with the logical channel based on the mapping information.

Abstract: In the present invention, a user equipment (UE) receives a paging message while using a paging discontinuous reception (DRX). The UE transitions from the paging DRX with a paging DRX cycle to an inactive DRX with an inactive DRX cycle if the paging message includes an indication that there is downlink data for the UE. The UE monitors a physical downlink control channel (PDCCH) using the inactive DRX to receive the downlink data.

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. 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 method for restarting a prohibit timer in a wireless communication system, the method performed by a user equipment (UE) includes starting the prohibit timer related to a transmission of power preference information; receiving, from a network, a handover message including a timer value; performing a handover procedure based on the received handover message; restarting the prohibit timer based on applying the received timer value included in the handover message; and stopping the prohibit timer based on whether the UE initiates radio resource control (RRC) re-establishment procedure while the prohibit timer is running. Further, upon initiating the RRC re-establishment procedure, the UE disables the transmission of the power preference information and stops the prohibit timer.
