A method and a device for transmission or reception based on a distributed resource unit tone plan in a wireless LAN system is disclosed. A method performed by a first STA in a WLAN system, according to one embodiment of the present disclosure, may comprise the steps of: generating a PPDU including one or more fields, the one or more fields being mapped onto one or more DRUs; and transmitting the PPDU to one or more second STAs on a bandwidth. At this time, on the basis that the one or more DRUs include a 26-tone DRU, 26 tones constituting the 26-tone DRU can be distributively allocated to a channel in which the PPDU is transmitted within the bandwidth. Here, a pilot tone of the 26-tone DRU corresponds to a tone of a position to which one of candidate shift values is applied with respect to the position of a pre-defined pilot tone, and the number of candidate shift values can be determined on the basis of the number of pilot tones of a DRU of the largest size that can be supported in the channel.

Disclosed are a method and an apparatus for generating and operating a privacy-protected address in a UWB wireless network system. A method performed by a first device in a UWB wireless network system according to an embodiment of the present disclosure may comprise the steps of: broadcasting a public-based advertising poll frame; in response to the public-based advertising poll frame, receiving a public-based advertising response frame from a second device; transmitting a public-based SOR frame to the second device; and after an initialization procedure based on the public-based advertising poll frame, the public-based advertising response frame, and the public-based SOR frame, performing a ranging session procedure with the second device. Here, a frame exchange in the ranging session procedure may be based on IRK information generated using information known to the first device and the second device via the initialization procedure.

Provided are a method for performing wireless communication by a first device, and a device for supporting same. The method may comprise the steps of: obtaining first radio link failure (RLF) configuration information related to a first altitude including information on a first maximum number of times of out-of-sync (OOS) related to the first altitude and information on a first RLF timer related to the first altitude, and second RLF configuration information related to a second altitude including information on a second maximum number of times of OOS related to the second altitude and information on a second RLF timer related to the second altitude; identifying the altitude of the first device as the first altitude; selecting the first maximum number of times of OOS related to the first altitude and the first RLF timer related to the first altitude on the basis of the altitude of the first device being identified as the first altitude; and starting the first RLF timer related to the first altitude on the basis of the number of times of OOS reaching the first maximum number of times of OOS related to the first altitude. For example, the number of times of the OOS may be increased on the basis of obtaining information on the OOS from a lower layer of the first device.

An image display device and a video wall including the same are disclosed. The image display device includes: a panel including a plurality of light emitting diodes; a driving controller to output a scan signal during each of a plurality of subframe periods, wherein the driving controller includes a buffer to store frame data, wherein in a first mode in which a frame rate or a vertical synchronization signal changes, in response to a frequency of the changed vertical synchronization signal being less than a reference frequency, the driving controller is configured to repeat the frame data stored in the buffer and output only some of subframe data within the repeated frame data without outputting another part of the subframe data. Accordingly, it is possible to reduce flicker when a frame rate or a vertical synchronization signal changes.
