    Abstract: An operation method of a station in a wireless local area network (WLAN) is disclosed. An operation method of a first station comprises generating a high efficiency (HE) preamble including scheduling information of a plurality of reception stations; and generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including a legacy preamble, the HE preamble, and a payload having data units to be transmitted to the plurality of reception stations. Therefore, a performance of WLAN may be enhanced.

    Abstract: In wireless communications for a 20 megahertz (MHz) channel bandwidth, a first device may determine a high efficiency long training field (HE-LTF) mode. The first device may generate an HE-LTF symbol by using a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and HE-LTF mode. The first device may transmit, in the channel bandwidth, a high efficiency physical layer protocol data unit (HE PPDU) that includes the HE-LTF symbol. A second device may receive, in the 20 MHz channel bandwidth, a downlink HE PPDU that includes an HE-LTF symbol. The second device may obtain, from the HE-LTF symbol, a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and an HE-LTF mode of the HE-LTF symbol. The downlink HE PPDU may be the HE PPDU from the first device. Other methods, apparatus, and computer-readable media are also disclosed.

    Abstract: The embodiments provide a method implemented by a network device for transmitting link adaptation feedback in a Wireless Local Area Network (WLAN) that supports multi-user simultaneous transmission. The method generates and transmits a frame that includes one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device. In one aspect, the one or more link adaptation feedback values may include a link adaptation feedback value for an entire operation bandwidth of the wireless communications link and a link adaptation feedback value for a given subchannel within the operation bandwidth. In another aspect, link adaptation feedback values for one or more users of a multi-user simultaneous transmission are transmitted in a multi-user acknowledgment (ACK) frame. The embodiments allow for efficient link adaptation in a multi-user simultaneous transmission environment.
