Abstract: A method and apparatus for recovery from deadlock after master cell group (MCG) failure report in a wireless communication system is provided. Upon detecting a master cell group (MCG) radio link failure (RLF), a wireless device transmits information for the MCG RLF to a secondary node (SN) by using a secondary cell group (SCG), and starts a timer. Upon expiry of the timer, the wireless device performs a connection re-establishment procedure.

Abstract: A method and apparatus for resuming only signaling radio bearers (SRBs) in a wireless communication system is provided. A wireless device triggers a signaling while the wireless device is in a radio resource control (RRC) inactive state, and resumes only SRB and transmits a message 3 (MSG3) of a random access procedure to a network when an early data transmission (EDT) triggering condition for transmission via the MSG3 is fulfilled. The MSG3 includes the signaling.

Abstract: One disclosure of the present specification provides a method for transmitting, by user equipment, a PDU session establishment request. The method comprises the steps of: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message, wherein the PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

Abstract: Provided in one disclosure of the present specification is a method for a wireless device attempting network access. The method may comprise the steps of: an RRC layer of the wireless device receiving, from a cell, a first piece of information relating to an NB-IoT RAT; the RRC layer receiving, from the cell, a second piece of information indicating whether to block access to exception data; the RRC layer obtaining, from an upper layer, an RRC establishment cause set as outgoing exception data, when an NAS signaling process is initiated to transmit the exception data; and performing an access block inspection.

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.
