Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.

Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.

Abstract: The application provides a short training sequence design method and apparatus. The method includes: determining a short training sequence, where the short training sequence may be obtained based on an existing sequence, and the short training sequence with comparatively good performance may be obtained through simulation calculation, for example, by adjusting a parameter; and sending a short training field on a target channel, where the short training field is obtained by performing inverse fast Fourier transformation IFFT on the short training sequence, and a bandwidth of the target channel is greater than 160 MHz.

Abstract: This disclosure provides data sending and receiving methods and apparatuses. In an implementation, a device performs a non-replication operation on a frequency domain sequence on subcarriers of a first bandwidth, to obtain a frequency domain sequence on subcarriers of a second bandwidth in a transmission bandwidth, transforms the frequency domain sequence on the subcarriers of the first bandwidth and the frequency domain sequence on the subcarriers of the second bandwidth into a time domain, and performs radio frequency processing on time domain data and then sends the processed time domain data.

Abstract: This application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for transmitting a physical layer protocol data unit, and for example, is applied to a wireless local area network. The method includes: A first communications device generates a PPDU and may send the PPDU, where the PPDU includes an LTF sequence; and correspondingly, a second communications device receives the PPDU, and parses the PPDU to obtain the LTF sequence included in the PPDU. Embodiments of this application can be used to design an LTF sequence that has a relatively low PAPR on entire bandwidth, on a single resource unit, on a combined resource unit, and in a considered multi-stream scenario.
