Abstract: This application provides a communication method and a communication apparatus. In one example, a first physical layer protocol data unit (PPDU) is sent over a first link, where the first PPDU carries a trigger frame. A second PPDU is sent over a second link. An end time of sending the second PPDU is not earlier than a first time and not later than a second time, the first time is related to an end time of sending the first PPDU and a state turnaround time, and the second time is related to the end time of sending the first PPDU and a short interframe space (SIFS) time.

Abstract: This application relates to the field of wireless communication, and in particular, to a multi-channel hybrid transmission technology. In an embodiment, a data transmission method comprises: generating, by a first wireless communications device, a physical protocol data unit (PPDU), wherein the PPDU comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal field (L-SIG), and two signature symbols after the L-SIG in a time-domain, and wherein the two signature symbols are identical and are modulated based on binary phase shift keying (BPSK), the two signature symbols identify a wireless communications standard the PPDU complies with; and transmitting, by the first wireless communications device, the PPDU to a second wireless communications device.

Abstract: The technology of this application relates to a communication method and apparatus, to not only improve transmission efficiency in a distributed resource unit (DRU) transmission mode, but also improve system performance due to a relatively low peak-to-average ratio (PAPR) of a long training field (LTF) included in a trigger-based physical layer protocol data unit (TB PPDU) transmitted based on a DRU. In an example embodiment, a station (STA) receives a trigger frame, where the trigger frame includes DRU indication information, and the DRU indication information indicates a DRU used by the STA to send a TB PPDU. The STA sends the TB PPDU on the DRU, where the TB PPDU includes a long training field (LTF).

Abstract: This application relates to the wireless communication field, and is applied to a wireless local area network that supports the 802.11be standard. In particular, this application relates to a method including: An access point AP sends a trigger frame, where the trigger frame is used for triggering a station to send an extremely high throughput trigger based physical layer protocol data unit EHT TB PPDU. The station determines, based on one or two of a value indicated by an uplink EHT spatial reuse parameter UL EHT SRP and a value indicated by one or more uplink spatial reuse parameter UL SRP fields in a common information field of the trigger frame, a value indicated by a spatial reuse parameter SRP in a universal signal field U-SIG of the EHT TB PPDU. The STA sends the EHT TB PPDU to the AP.

Abstract: This application provides a communication method and a multi-link device. The method includes: When only one of a plurality of links is successfully established, a first MLD performs air interface transmission with a second MLD according to a single-link communication rule. The plurality of links may be a plurality of links that the first MLD requests to establish, or the plurality of links may be a plurality of links that have been successfully established between the first MLD and the second MLD. According to the solution in this application, when only one of the plurality of links is successfully established, the first MLD does not perform air interface transmission with the second MLD according to a multi-link communication rule. Specifically, an address 2 field carried in a frame over the air that is sent by the first MLD is a MAC address of the first MLD.
