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.

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: A receiving system information method includes monitoring a first system information (SI) monitoring window based on a first frequency. Receiving frequency pattern information on the first frequency, when a signal is not detected in the first SI monitoring window. Monitoring a second SI monitoring window on a second frequency based on the frequency pattern information.

Abstract: Provided is a method for carrying out access control in a radio resource control (RRC) connected mode according to a disclosure of the present specification. The method may comprise the steps of: a non-access stratum (NAS)layer of a terminal determining an access category if outgoing (MO) data to be transmitted or outgoing (MO) signaling occurs; the NAS layer transmitting the NAS signaling message and access category to an access stratum (AS) layer if no disconnection is determined as a result of carrying out a termination test for access control on the basis of the access category; and the AS stratum of the terminal transmitting, to a base station, an RRC message comprising at least one from among the access category, call type, and reason for setup.

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.
