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, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.

Abstract: This application relates to the field of wireless communication, and in particular, to individually addressed traffic indication methods and apparatuses applicable to multiple links, for example, in a wireless local area network supporting an 802.11be standard. In an example method, a first access point (AP) of a first access point multi-link device (AP MLD) generates and sends individually addressed traffic indication information. The individually addressed traffic indication information is used to indicate whether a non-AP MLD associated with the first AP MLD has a downlink individually addressed traffic and whether a non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic. The second AP MLD is an AP MLD to which a non-transmitted AP belongs. The non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which the first AP is located.

Abstract: A trigger based null data packet transmission method and a related apparatus are provided, which relate to wireless communication, and are applied to a wireless local area network supporting an 802.11be standard. The method includes: receiving, by an EHT station, an NFRP trigger frame; determining whether a resource for scheduling the EHT station is in an EHT modulation bandwidth or an HE modulation bandwidth based on information in the NFRP trigger frame; and sending an EHT TB NDP if the resource is in the EHT modulation bandwidth; or sending an HE TB NDP if the resource is in the HE modulation bandwidth, where the NFRP trigger frame includes a first user information field, and is used to schedule the EHT station to send the HE TB NDP in the HE modulation bandwidth and send the EHT TB NDP in the EHT modulation bandwidth.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. The method includes: An AP generates a trigger frame, where the trigger frame includes a first user information field, a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field before the first user information field is located on a primary 160 MHz channel, and a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field after the first user information field is located on a secondary 160 MHz channel. Then, the AP sends the trigger frame.

Abstract: In an information transmission method, a receiving device receives a data frame from a sending device. The data frame occupies a transmission resource block, and includes RU allocation information. The receiving device determines indication information based on a location of a 160 MHz channel with more data tones of the transmission resource block and a resource block size indicated by the RU allocation information. The receiving device then determines a response resource block based on the indication information and the RU allocation information, and sends an acknowledgment frame for the data frame to the sending device on the response resource block.

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 STAMLD 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: A method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a data field; and sending the PPDU to a first station and a second station, where the first station is a station that does not support receiving a midamble, and the second station is a station that supports receiving the midamble. A second data field transmitted on a second resource unit allocated to the second station includes a midamble subfield. A first data field transmitted on a first resource unit allocated to the first station includes a useful information subfield. The useful information subfield includes useful data information, and the useful information subfield is located before a first OFDM symbol corresponding to the midamble subfield.
