Abstract: A method and apparatus for performing a conditional mobility based on a congestion level in a wireless communication system is provided. That is, the congestion level may be considered as mobility triggering condition of the conditional mobility. A wireless device performs a congestion level measurement, and receives a conditional mobility configuration associated with multiple target cells from a serving node. The conditional mobility configuration includes a threshold for the congestion level. The wireless device performs a mobility towards one target cell among the multiple target cells based on a result of the congestion level measurement and the threshold for the congestion level.

Abstract: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: According to an embodiment of the present invention, a user equipment (UE) may receive one or more physical downlink control channels (PDCCHs) each carrying downlink control information (DCI) including a field indicating a transmitting configuration index (TCI) state, and receive, based the one or more PDCCHs, one or more of a plurality of physical downlink shared channels (PDSCHs), wherein the plurality of PDSCHs may carry a same transport block (TB) in a plurality of TCI states, respectively, and the UE can determine, for each TCI state, whether a hybrid automatic repeat request (HARQ) operation is enabled or disabled, and transmits HARQ-acknowledgement (ACK) information for the same TB through a physical uplink control channel (PUCCH) associated with an HARQ operation-enabled TCI state.

Abstract: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

Abstract: A method for a terminal to determine whether or not to suspend a radio bearer in a wireless communication system and a device supporting the method are provided. The method may comprise: a step of receiving, from a base station, a configuration indicating if data transmission through a certain radio bearer is permitted in an RRC_INACTIVE state; a step of entering the RRC_INACTIVE state; and a step of determining, based on the configuration, whether or not to suspend the certain radio bearer in the RRC_INACTIVE state.

Abstract: A method and apparatus for handling bearers based on congestion level in a wireless communication system is provided. A wireless device configures at least two lower entities associated with an upper entity for multiple frequencies. A wireless device selects at least one lower entity among the at least two lower entities based on a congestion level of at least one frequency among the multiple frequencies. A wireless device submits a data unit to the at least one lower entity based on the selection. A wireless device performs transmission of the data unit.

Abstract: A method and apparatus for multiple accesses for fast connection reestablishment in a wireless communication system is provided. Upon detecting a failure, a wireless device selects multiple resources of one cell based on a type of the failure. Then, the wireless device triggers multiple access procedures each of which is mapped to each of the multiple resources of the one cell respectively, and performs multiple access transmissions for the multiple access procedures via the multiple resources of the one cell.

Abstract: Provided are a method for a terminal requesting a radio resource control (RRC) connection in a wireless communication system, and a device supporting same. The method may comprise the steps of: receiving a UE ID from a first cell; determining whether the UE ID is valid; and transmitting an RRC connection resume request message including the UE ID to a second cell if the terminal determines that the UE ID is valid.

Abstract: Disclosed are methods for transmission and reception of a paging channel between user equipment (UE) and a base station in a wireless communication system. In particular, the present invention may comprise the steps of: receiving, in a paging occasion of UE, a control channel for a paging channel; attempting to receive the paging channel on the basis of downlink control information (DCI) including information indicating a retransmission time of the paging channel; and if reception of the paging channel fails, reattempting to receive the paging channel at the retransmission time indicated by the DCI.
