Abstract: According to various embodiments, a receiving station (STA) may receive a physical layer protocol data unit (PPDU). The PPDU may include a first signal field and a second signal field. The first signal field may include 3-bit information. The receiving STA may determine whether the PPDU is related to single user (SU) transmission or multiple user (MU) transmission, whether the PPDU is related to orthogonal frequency division multiple access (OFDMA), whether the PPDU is related to multi-user multiple input multiple output (MU-MIMO), and whether the PPDU is related to a trigger-based (TB) PPDU, based on the 3-bit information.

Abstract: Presented are a method and device for transmitting a wakeup packet in a wireless LAN system. Specifically, the transmission device configures a first wakeup packet having a first data rate by using a first sync field, and a second wakeup packet having a second data rate by using a second sync field. The transmission device transmits the first and second wakeup packets to a receiving device. Here, an OOK scheme is applied to the first and second wakeup packets to configure the first and second wakeup packets as an ON signal or an OFF signal. The first sync field includes a first sequence, and the second sync field includes a second sequence which is a complementary sequence to the first sequence. The number of coefficient 1 and coefficient 0 included in the first sequence is the same. The first and second sequences have a 32 bit length, and each bit of the first and second sequences has a duration of 2 μs.

Abstract: An embodiment of the present invention suggests a method in which an access point (AP) obtains channel quality information in a wireless LAN system. The AP transmits, to at least one station (STA), a null data packet announcement (NDP-A) frame including information on transmission of a subsequent null data packet (NDP) frame, and transmits an NDP frame to the at least one station on the basis of information on the NDP-A frame. Further, the AP receives, from the at least one STA, a feedback frame including downlink channel quality information. At this time, the NDP frame includes an L-part for a legacy STA and a high efficiency (HE)-part for a HE STA, wherein the HE-part consists of a HE-signaling A (HE-SIG A) field, a HE-short training field (HE-STF), and a HE-long training field (HE-LTF).
