Abstract: Provided is a cell reselection method performed by a terminal in a wireless communication system. The method includes: receiving first priority information for at least one frequency; receiving second priority information for the one or more frequencies; and selectively applying, based on the state of the terminal, any one of the first priority information and second priority information and performing cell reselection. The first priority information is provided through a connection rejection message and provides instructions on the priority for the one or more frequencies to be lowered. The second priority information is provided from a current cell through system information.

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: Provided is a method and device for selectively transmitting a secondary cell group (SCG) failure information message to one of a master node (MN) and a secondary node (SN) in a wireless communication system. A user equipment (UE) detects a failure related to an SCG, and selectively transmits an SCG failure information message to one of an MN and an SN according to a reason for the failure related to the SCG. For example, if the reason for the failure related to the SCG is associated with the size of a hybrid automatic repeat request (HARQ) buffer, the UE ma transmit the SCG failure information message to the SN.

Abstract: In a wireless communication system, a user equipment (UE) may reselect a sidelink resource to be used for vehicle-to-everything (V2X) communication. The reselection of sidelink resource may be triggered by various conditions. In particular, the reselection of the sidelink resources may be triggered when a value of sidelink resource reselection counter is zero. More specifically, the UE determines that data for the V2X communication is available in a sidelink traffic channel (STCH), determines that a value of the sidelink resource reselection counter is zero, and reselects the sidelink resources.

Abstract: The present application provides a method for transmitting or receiving a sidelink signal by a terminal in a wireless communication system. Specifically, the method for transmitting or receiving a sidelink signal comprises the steps of: transmitting a first sidelink signal during a transmission period by using a transmission resource selected among resource units included in a first transmission resource pool; monitoring resource units included in a second transmission resource pool; and transmitting a second sidelink signal during the transmission period by using a selected transmission resource on the basis of a result of the monitoring among the resource units included in the second transmission resource pool when a resource pool changes from the first transmission resource pool to the second transmission resource pool, wherein the second transmission resource pool is included in a reception resource pool corresponding to the first transmission resource pool.
