    Abstract: This application relates to the field of WLAN technologies, and in particular, to a null data physical layer protocol data unit transmitting method and an apparatus, and may be used in a wireless communication system that supports the 802.11be standard or the EHT standard. In the method, a first device transmits a sensing NDPA frame, where the sensing NDPA frame indicates to transmit an NDP; and then, the first device transmits the NDP, where the NDP is a first NDP or a second NDP. A physical layer version of the first NDP is different from a physical layer version of the second NDP. Correspondingly, a second device receives the sensing NDPA frame and the NDP from the first device.

    Abstract: Methods and devices are disclosed for transmitting data, including segmenting a group of information bits into a set of information blocks that each include a respective plurality of the information bits; encoding, using low density parity check (LDPC) encoding, each of the information blocks to generate corresponding codewords; transmitting the codewords to a destination station; receiving a feedback message indicating that at least one of the codewords has not been successfully decoded by the destination station; interleaving the information bits of the information block that corresponds to the at least one of the codewords; encoding, using low density parity check (LDPC) encoding, the interleaved information bits to generate an interleaved codeword; and transmitting the interleaved codeword to the destination station.

    Abstract: A method includes sending, by an access point (AP) to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a common information field. The common information field including an indicator of whether trigger based (TB) sounding or non-trigger based (non-TB) is being used. Then, the method includes receiving, by the AP from the one or more STAs, a CSI feedback response based on the request. The common information field may be a null data packet announcement (NDPA) variant field in an alternative name and the indicator may utilize 1 bit.

    Abstract: The present disclosure provides for methods, systems and apparatus related to Variable High Throughput (HT) Control Field. An aspect of the disclosure provides for a method performed by a station (STA). The method includes sending, to a second STA, a message including a frame, the frame including a variable high throughput (HT) control field. The variable HT further includes a first subfield indicating an N number of control IDs, wherein N is equal to or more than one. The variable HT further includes N additional subfields. Each of the N additional subfield includes: a control identifier (ID) field and a control information field associated with the Control ID field. The method further includes receiving, from the second STA, a response.

    Abstract: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.
