Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: transmitting a first radio resource control (RRC) message for the EDT, to a base station; receiving a second RRC message in response to the first RRC message, from the base station; if the second RRC message indicates that the EDT is successful, considering that the EDT ends successfully; if the second RRC message indicates that the EDT is unsuccessful, considering that the EDT ends unsuccessfully; and entering a RRC_IDLE state.

Abstract: A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

Abstract: The present invention relates to a method for transmitting signals by a user equipment (UE) in a radio resource control (RRC) inactive state or a RRC idle state at a wireless communication system. In particular, the method includes the steps of: measuring neighboring cells; identifying one of the neighboring cells fulfilled with conditions for a cell reselection procedure based on a result of measuring; determining whether to perform the cell reselection procedure with the one of the neighboring cells by considering a timer; and transmitting an uplink data or receiving a downlink data, without performing the cell reselection procedure during the timer is running, when it is determined not to perform the cell reselection procedure.

Abstract: A method and apparatus for frequency band allocation for transmission based on a paging in a wireless communication system is provided. A wireless device receives, from a network, system information including a list of physical resource blocks (PRBs). While in an idle state and/or an inactive state, the wireless device monitors a paging including information indicating at least one PRB from the list of the PRBs, and communicates with the network based on the at least one PRB.

Abstract: Provided are a method for a user equipment (UE) to perform access barring check in a wireless communication system, and an apparatus supporting the same. The method may include: receiving a list of barring information, wherein each of the barring information includes a barring factor and a barring time; receiving information on an access category related to barring information included in the list; performing the access barring check for the access category, based on the barring information related to the access category; and performing uplink transmission, if an access attempt is allowed for the access category.

Abstract: A method and apparatus for random access fallback procedure related to MT EDT in a wireless communication system is provided. A wireless device receives, from the network, a paging including a dedicated random access (RA) resource corresponding to a first coverage enhancement (CE) level. A wireless device initiates a first RA attempt using the dedicated RA resource. A wireless device increases a CE level of the wireless device to a second CE level based on failure of the first RA attempt. A wireless device selects a non-dedicated RA resource corresponding the second CE level. A wireless device performs a second RA attempt using the non-dedicated RA resource.

Abstract: A method and apparatus for start and stop of reception of downlink (DL) transmission based on a paging in a wireless communication system is provided. A wireless device, upon receiving a paging, resumes a radio bearer in an idle state (e.g., RRC_IDLE) and/or an inactive state (e.g., RRC_INACTIVE).
