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 method and apparatus for configuring multiple common control channels (CCCHs) in a wireless communication system, specifically in a new radio access technology (NR) system, is provided. A user equipment (UE) configures a first CCCH and a second CCCH. The first CCCH has higher priority than the second CCCH in a logical channel prioritization (LCP) procedure. Upon detecting that data is available for the first CCCH and the second CCCH, the UE constructs a media access control (MAC) protocol data unit (PDU) including the data, based on a priority of the first CCCH and a priority of the second CCCH, and transmits the MAC PDU to a network.

Abstract: The present disclosure relates to random access in mobility in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device comprises: receiving, from a network, skip information for a random access channel (RACH) and information for a revert timer; performing a RACH-less handover to a target cell based on the skip information and starting the revert timer; determining that the RACH-less handover stops while the revert timer is running; and upon an expiry of the revert timer, transmitting a random access preamble with a ramped transmission power, wherein the ramped transmission power is higher than an initial transmission power of the random access preamble.

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 present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: Disclosed embodiments include a method and a device for transmitting UL packet based on QoS flow, the method including receiving uplink (UL) packet from an upper layer; checking whether a IP flow of the UL packet is matched to any of UL IP flow to QoS flow mapping defined in QoS rules configured to the UE; setting a QoS Flow ID of the UL packet to a special value if a IP flow of the UL packet is not matched to any of UL IP flow to QoS flow mapping defined in the QoS rules configured to the UE; and transmitting the UL packet with the QoS Flow ID set to the special value to a network via a DRB. 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 calculating a channel busy level (CBL) by a user equipment in a wireless communication system is disclosed. The method comprises monitoring a plurality of synchronization signal/physical broadcast channel (SS/PBCH) blocks within a predetermined window; calculating the CBL by counting dropped SS/PBCH blocks among the plurality of SSBs; configuring parameters for a specific procedure based on the calculated CBL; and performing the specific procedure by using the configured parameters.

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.
