    Abstract: A data communication method and a related apparatus are provided, and the data communication method includes: constructing, by an access device, a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device; and broadcasting, by the access device, the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. By using the present invention, data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.

    Abstract: A transmit end sends a physical layer protocol data unit (PPDU) to a receive end, where a bandwidth of the PPDU is P×10 MHz. The PPDU includes a first part of fields and a second part of fields. A quantity of tones per 10-MHz tone distribution corresponding to the first part of fields is 64, and a tone spacing is 156.25 kHz. A quantity of tones per 10-MHz tone distribution corresponding to the second part of fields is 128, and a tone spacing is 78.125 kHz. The corresponding method is applicable to 10 MHz, 20 MHz, 40 MHz, 60 MHz, so that a transmission bandwidth is increased compared with that of 802.11p, as well as a system throughput. The transmit end may transmit data by some RUs to increase a data transmission distance, or may simultaneously transmit data of different services by a plurality of RUs to improve data transmission efficiency.

    Abstract: Embodiments of the present invention disclose a data processing method and apparatus, and belong to the field of communications technologies. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a preamble field, a data field, and a middle preamble field, and the preamble in the PPDU includes information used to indicate an insertion frequency of the middle preamble in the data field in the PPDU; and sending the PPDU. The insertion frequency of the middle preamble in the data field is indicated by using a specified field in the preamble. In this way, in different scenarios, the middle preamble may be inserted into the data field at different frequency, thereby reducing overheads of an inserted pilot and improving data transmission performance.

    Abstract: Methods, apparatus, and systems for joint transmission are provided. In one aspect, a joint transmission method includes: sending, by a first AP, a first PPDU to a first STA and a second STA, and sending, by a second AP, a second PPDU to the first STA. A sending time of sending the first PPDU is same as a sending time of sending the second PPDU. The first PPDU includes a first preamble field and a first data field, and the second PPDU includes a second preamble field and a second data field. The first preamble field is same as the second preamble field. The first data field carries first data information sent to the first STA and second data information sent to the second STA, and the second data field carries the first data information.

    Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.

    Abstract: A coordinated transmission control method, apparatus, and system are disclosed. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test, further determine an anti-interference beamforming manner based on a specific cell configuration parameter, and determine whether to perform coordinated transmission with reference to the dual decision condition of the interference test, so that the access points can learn an interference status in advance, thereby preventing unnecessary retransmission resulting from interference caused during actual coordinated transmission, and improving communication efficiency.
