Abstract: A method and apparatus for random access procedure based on a channel access priority class in a wireless communication system is provided. A wireless device transmits a random access preamble including a random access preamble identifier (RAPID). A wireless device receives, from a network, a downlink message including the RAPID and a specific channel access priority class (CAPC) mapped to the RAPID. A wireless device performing LBT procedure based on the specific CAPC. A wireless device transmits, to a network, an uplink message based on the downlink message.

Abstract: A method and apparatus for transmitting data in a wireless communication system is provided. A user equipment (UE) transmits the data in a first cell during a first random access procedure, i.e. early data transmission. The UE detects that transmission of the data in the first cell during the first random access procedure has failed, and prioritizes a second cell based on candidate cell information. After selecting the second cell, the UE transmits a failed part of the data in the second cell during a second random access procedure.

Abstract: Provided are a method of performing random access procedure and a device supporting the method. According to one embodiment of the present invention, a method for performing random access procedure in a wireless communication system includes: initiating a first random access procedure for system information (SI) request; triggering a state transition of the UE, before the first random access procedure is completed; stopping the first random access procedure; and initiating a second random access procedure for the state transition of the UE.

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: receiving system information including a threshold for the EDT; determining whether or not a condition for initiating the EDT is satisfied, by comparing the threshold for the EDT with a size of data for transmission; if the condition is satisfied, performing the EDT; and if the condition is not satisfied, performing a radio resource control (RRC) connection establishment or resume procedure.

Abstract: Disclosed are a method for performing a cell reselection procedure by a terminal, and an apparatus supporting the same. The method comprises the steps of: measuring a first CE level in a serving cell where the terminal is currently staying; measuring a second CE level in a neighboring cell where an MBMS service of interest is provided; calculating a ranking of the neighboring cell by adding an offset to a quality value measured for the neighboring cell, when the second CE level is higher than or equal to the first CE level; and performing a cell reselection procedure on the basis of the calculated ranking.
