Abstract: Disclosed are an overload control method in a wireless communication system and a device for the same. Specifically, a method by which a base station performs an overload control in a wireless communication system can include: a step of receiving an overload start message from a core network; a step of receiving a first radio resource control (RRC) message including a non-access stratum (NAS) message from user equipment (UE); and a step of transmitting an RRC connection release message, for instructing the release of an RRC connection, to the UE when an instruction for instructing data transmission through a control plane in the first RRC message is included.

Abstract: A method and apparatus for sidelink connection request based on congestion level for establishing a direct connection between wireless devices is provided. A first wireless device triggers a signaling procedure based on a congestion level of at least one carrier, selects a carrier among the at least one carrier, and transmits a message in the signaling procedure on the selected carrier. Upon receiving the message, a second wireless device may perform carrier reselection.

Abstract: A core network to which a cell of a base station can be connected may not be specified to be one. For example, a cell may be connected to an EPC, may be connected to a next-generation core network, or may be connected to both an EPC and a next-generation core network. The base station may transmit core network information relating to a core network to which the cell is connected, on the cell. A user equipment may determine whether to camp on the cell on the basis of the core network information.

Abstract: A disclosure of the present specification provides a method for transmitting a radio resource control (RRC) message by a wireless device. The method may comprise the steps of: acquiring, by an access stratum (AS) layer of a wireless device, at least one of the value and indication of an RRC establishment cause field from a non-access stratum (NAS) layer which requests transmission of an NAS signaling request message; transmitting, to a base station, an RRC connection request message including the at least one of the value and indication of the RRC establishment cause field; and when the at least one of the value and indication of the RRC establishment cause field is set to a value, which indicates that the NAS signaling request message includes user data, according to an optimization scheme through a control plane (CP), if a network is in an overload state, receiving an RRC connection rejection message or an RRC connection release request message from the base station.

Abstract: A method for performing vehicle-to-everything (V2X) communication in a wireless communication system and a device for same are disclosed. Particularly, a method for a user equipment (UE) performing V2X communication by means of a PC5 interface in a wireless communication system comprises the steps of: receiving from an upper layer a request for transmitting a V2X message; requesting radio resources, for V2X communication by means of a PC5 interface, to a base station or selecting radio resources for V2X communication by means of the PC5 interface; and performing transmission of V2X communication by means of the PC5 interface, wherein, if a UE has emergency packet data network (PDN) connection, an indication, indicating that transmission by means of the emergency PDN connection is a higher priority than the V2X communication by means of the PC5 interface, can be transmitted from the upper layer.

Abstract: The present disclosure relates to an image display apparatus. The image display apparatus according to an embodiment of the present disclosure includes a controller to output an image signal and a first DC power; and a display to receive the image signal, the first DC power, and a second DC power, wherein the display includes: a first interface to receive the image signal and the first DC power; a timing controller to output a data driving signal and a gate driving signal; a panel to display an image; a second interface to receive a second DC power; a backlight to output light to the panel based on the second DC power; and a first current detector to detect a first current based on the first DC, wherein the controller determines that the timing controller or the panel is failed, when the detected first current deviates from a first allowable range. Accordingly, it is possible to easily determine whether there is a failure in the image display apparatus that can be installed externally.

Abstract: The present disclosure provides a method for receiving a paging message, by a user equipment (UE) in a radio resource control (RRC) connection suspended state, in a wireless communication system. The method includes receiving the paging message from an evolved Node B (eNB); checking an indicator indicating whether the eNB stores a UE context, wherein the indicator is included in the paging message; and transmitting an RRC connection-resume request message or an RRC connection request message to the eNB based on the indicator.
