    Abstract: A transmitter sends a PPDU including a signature symbol to a receiver, where a first preset bit in the signature symbol indicates a standard version corresponding to the PPDU and/or a value of each bit in a second preset bit is 0 or 1. After the receiver receives the PPDU, if the standard version corresponding to the PPDU indicated by the first preset bit in the signature symbol in the PPDU is a standard version corresponding to a first PPDU and/or the value of each bit in the second preset bit in the signature symbol is the same as the preset value, the receiver determines that the received PPDU is the first PPDU. the transmitter and the receiver determine, by using the signature symbol in the PPDU, whether the received PPDU is the first PPDU, to identify the first PPDU, so that information in the received PPDU is correctly interpreted.

    Abstract: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

    Abstract: This application provides a channel access method and an apparatus, and relates to the field of communication technologies, to resolve a problem that it is difficult for a long range communication device to access a channel, and communication efficiency is low. The method includes: A first device detects a channel status in first duration. If a channel is in an idle state, M is subtracted from a value of a first counter, where M is a positive integer greater than 1. If the value of the first counter is greater than 0, the first device detects the channel status in next first duration; or if the value of the first counter is less than or equal to 0, the first device transmits data through the channel.

    Abstract: This application provides a data transmission method and a related apparatus. The method includes: A network device generates a first physical layer protocol data unit PPDU. The first PPDU includes a first universal-Signaling field U-SIG field and a first extremely high throughput-Signaling field EHT-SIG field, a sum of a quantity of information bits of the first U-SIG field and a quantity of information bits of the first EHT-SIG field is less than or equal to 78 information bits, and at least one of the first U-SIG field and the first EHT-SIG field includes an identifier indication field, where the identifier indication field is used to uniquely identify one station. The network device sends an encoded first PPDU to a station.

    Abstract: This application provides example data retransmission methods and communication apparatuses. One example method includes receiving a physical protocol data unit (PPDU) by a first device and from a second device, where the PPDU includes a signaling field and a data field, the data field includes retransmitted data and newly transmitted data, the signaling field includes first indication information, or the signaling field comprises the first indication information and second indication information, the first indication information indicates a first modulation and coding scheme (MCS) and a first coding mode that are used for the newly transmitted data, and the second indication information indicates a second MCS and a second coding mode that are used for the retransmitted data. The PPDU is demodulated based on the signaling field.

    Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.
