Abstract: In a wireless local area network system including a plurality of types of access points (APs), a first type AP receives a trigger frame from a second type AP, wherein the trigger frame may include first information related to resource allocation for a first block acknowledgment (BA) frame transmitted by a station (STA) to the first type AP. The first type AP may transmit, to the STA, a physical protocol data unit (PPDU) including data for the STA and the first information. The first type AP may receive, from the STA, the first BA frame on the basis of the first information.

Abstract: An image display apparatus is disclosed. The image display apparatus includes a display including an organic light emitting diode panel and a controller configured to control the display, wherein the controller is configured to display a first input image, in the case in which a second image having higher luminance than the first image is input after the first image, increase the luminance of the second image during a first period, and decrease the luminance of the second image after the first period. Consequently, it is possible to prevent glare while preventing luminance decrease at the time of scene change of an input image.

Abstract: A method for beamforming training and a device using the same are provided. A station (STA) receives a beacon frame from an access point (AP) during a beacon transmission interval (BTI). The beacon frame includes information on a sector sweep (SSW) frame type used in at least one of a plurality of SSW slots. During association beamforming training (A-BFT), the STA transmits the SSW frame according to the SSW frame type from an SSW slot, among a plurality of SSW slots, having succeeded in a random backoff.
