Abstract: A method for transmitting an extremely high throughput long training field (EHT-LTF) sequence includes: A first communication device generates and sends an extremely high throughput physical layer protocol data unit (EHT PPDU), where the EHT PPDU includes an EHT-LTF; and correspondingly, a second communication device receives the EHT PPDU, and parses the EHT-LTF in the received EHT PPDU. In this way, an LTF sequence can be designed for the IEEE 802.11be standard, and a PAPR value of the LTF sequence on a resource unit can be reduced.

Abstract: This application describes resource unit indication methods, access points, and stations. In an example method, a resource unit allocation subfield in a trigger frame includes a frequency band range indication and a resource unit indication. The resource unit indication is used to indicate a multi-resource unit (MRU) allocated to a station. The frequency band range indication is used to indicate a frequency band range in which a resource unit (RU) in the MRU is located. For example, the frequency band range indication is used to indicate 80 MHz in which a smallest RU in the MRU is located.

Abstract: An example physical layer protocol data unit (PPDU) transmission method includes generating, by a first communication device, a PPDU, where the PPDU includes a long training field (LTF) sequence. The first communication device can send the PPDU. A second communication device can receive the PPDU. The second communication device can parse the received PPDU to obtain the LTF sequence included in the PPDU.

Abstract: A first station in a first multi-link device generates a frame, wherein the frame indicates a maximum quantity of shared spatial streams supported by the first multi-link device. The first station sends the frame. A throughput of a station in a multi-link device is improved by enabling a station to use more spatial streams.

Abstract: A method includes: A multi-link device performs first channel contention on a first link, where an initial value of a backoff counter in the first channel contention is determined based on a first value of a contention window. The multi-link device may perform second channel contention on the first link when a value of the backoff counter becomes 0 in the first channel contention and the multi-link device does not perform transmission on the first link, where an initial value of the backoff counter in the second channel contention is determined based on a second value of the contention window, and the second value is equal to the first value or a minimum value of the contention window.

Abstract: Embodiments of this application provide a communication method applied to a multi-link device in a wireless local area network WLAN and a related apparatus. The method includes: A reporting AP sends a management frame to a station. The reporting AP belongs to a first AP MLD, and belongs to a multiple BSSID set. The management frame includes MLD information. The MLD information carries, by using different types of MLD elements and a multiple BSSID element, for example, information about another AP in the MLD to which the AP belongs, information about the multiple BSSID set to which the AP belongs, and information about an AP in a multiple BSSID set including the another AP in the MLD to which the AP belongs. The station obtains information about the reporting AP and other information about a reported AP based on the management frame.

Abstract: This application discloses a data transmission method that includes: scrambling to-be-transmitted data, to obtain scrambled data; and sending the scrambled data to a receive device. The initialization bits of a scrambler used to scramble the data include a first bit sequence and a second bit sequence. The first bit sequence is carried in a service field of the to-be-transmitted data, the second bit sequence reuses a bit in a signal field of a physical layer protocol data unit (PPDU), and the quantity of the initialization bits is equal to the order of the scrambler. In embodiments of this application, when the transmit device and the receive device use the scrambler with a higher order than that in the conventional technology, the initialization bits of the scrambler are based on bits in an existing service field used for data scrambling and reused bits in some signal fields.

Abstract: This application provides a bandwidth indication method applied in a wireless local area network supporting the 802.11be standard and a communication apparatus. The method includes: An access point generates a physical layer protocol data unit PPDU, where a transmission bandwidth of the PPDU is divided into a plurality of segments, the PPDU includes a universal signal U-SIG field carried on a segment, the U-SIG field includes a bandwidth field, and the bandwidth field indicates a channel bandwidth of a resource unit allocated to a station parked in the segment; and the access point sends the PPDU to the station. The method in this application can be used to reduce signaling overheads of PPDU transmission, and resources across segments can be allocated to the station, so that resources can be more flexibly allocated.
