Abstract: In a wireless local area network (LAN) system, a sharing access point (AP) can determine a Q-matrix related to a first antenna of a first shared AP, a second antenna of the first shared AP, a third antenna of a second shared AP, and a fourth antenna of the second shared AP. The sharing AP can transmit, to the first shared AP, a first value related to the first antenna and a second value related to the second antenna in the Q-matrix. The sharing AP can transmit, to the second shared AP, a third value related to the third antenna and a fourth value related to the fourth antenna in the Q-matrix.

Abstract: An AP and a STA can perform a PHY-level HARQ operation in a wireless local area network system, and the AP can transmit resource allocation information about a PHY-level feedback frame to be transmitted by a plurality of STAs. The AP can receive a plurality of HARQ feedback frames from a plurality of STAs. The plurality of HARQ feedback frames are PHY layer signals. The resource allocation information can include information related to a tone set and a symbol from which transmission of the plurality of HARQ feedback frames are started.

Abstract: A signal processing device and an image display apparatus including the same are disclosed. The image display apparatus includes a display including an organic light emitting diode panel and a signal processor configured to control the display, wherein the signal processor is configured to perform luminance conversion based on a first luminance conversion pattern in the case in which the luminance level of an input image is greater a first level and to perform luminance conversion based on a second luminance conversion pattern having a higher luminance level than the first luminance conversion pattern in the case in which the luminance level of the input image is equal to or less than the first level, whereby low gray level expression of the organic light emitting diode panel is improved.
