Abstract: In the present invention, a user equipment (UE) receives an UL grant that can be used while the UE is not in RRC_CONNECTED state. If the UE receives a message indicating to leave RRC_CONNECTED state, the UE starts a time alignment timer (I-TAT) when the UE leaves RRC_CONNECTED state. The UE transmits UL data using the UL grant if the UL data becomes available for transmission when the UE is not in RRC_CONNECTED state and if the I-TAT is running

Abstract: A method for transmitting signals by a medium access control (MAC) entity of a transmission end in a wireless communication system is disclosed. The method includes steps of receiving a protocol data unit (PDU) from a Radio Link Control (RLC) layer; transmitting a signal including the PDU based on a specific coverage enhanced (CE) level to a network; when a transmission of the signal to a network is failed, determining whether a current CE level is changed or not from the specific CE level; if the current CE level is changed from the specific CE level, transmitting an indication requesting a retransmission of the PDU, to the RLC layer; receiving the PDU from the RLC layer; and transmitting a signal including the PDU based on the current CE level to the network.

Abstract: In the present invention, a UE configured with a SPS resource which occurs periodically for a predetermined time duration transmits indication information using the last SPS resource which occurs last in the predetermined time duration, if the last SPS resource is not sufficient to accommodate uplink data available for transmission. The indication information informs a network that there is uplink data remaining after the UE performs uplink data transmission on the last SPS resource.

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: Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam having a quality equal to or higher than a preconfigured threshold value; transmitting a random access preamble to a base station via the first beam; adjusting the threshold value when it is determined that the random access procedure has failed; and reselecting a second beam having a quality equal to or higher than the adjusted threshold value.

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: The method for a user equipment (UE) transmitting a buffer status report (BSR) comprises receiving logical channel configuration information from a network, the logical channel configuration information including information related to a plurality of numerologies mapped to each logical channel; when the BSR is triggered, selecting a buffer size reporting numerology for each logical channel; calculating a buffer size for a numerology by including a buffer size of logical channels having the buffer size reporting numerology as the numerology; and reporting the BSR including information of the calculated buffer size.
