Abstract: A method of an IAB node may comprise: receiving an RRC message including measurement control information from a base station; transmitting RRC reconfiguration information including the measurement control information to each of a plurality of terminals; receiving a measurement report message including a measurement report generated by each of the plurality of terminals based on the measurement control information from each of the plurality of terminals; and grouping the measurement report messages received from the plurality of terminals into a grouped message report message, and transmitting the grouped measurement report message to the base station according to a grouped measurement reporting periodicity.

Abstract: A method of a terminal, according to an exemplary embodiment of the present disclosure, may include: requesting access to a mobile integrated access backhaul (IAB) based on cell search; receiving a tracking area (TA) update procedure stop request message from an Access and Mobility Management Function (AMF) of a core network; and deactivating a TA update procedure based on the TA update procedure stop request message.

Abstract: A method of an integrated access and backhaul (IAB) node may include: receiving, from a target base station, one or more user equipment (UE) context setup request messages including terminal radio resource reconfiguration information; sharing context information including the terminal radio resource reconfiguration information with a source IAB-distributed unit 1 (IAB-DU1); configuring terminal reconfiguration information using the shared context information; and transmitting one or more UE context setup response messages including the terminal reconfiguration information to the target base station in response to the one or more UE context setup request messages.

Abstract: Provided is a display device including a display panel, an optical sensor, a timing controller, a scan driver, a data driver, and an image controller. The timing controller controls an image refresh rate of the display panel based on a refresh rate control signal. Thus, the display device provides improved visibility.

Abstract: Disclosed is a method for manufacturing a semiconductor light-emitting device, which carries out a wet-etching process after a dry-etching process so as to form protrusions in a surface of a substrate for growing a nitride semiconductor material thereon.
