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.

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 discloses a communication method and apparatus, to resolve an existing problem that a large quantity of time-frequency resources are occupied for indicating a quantity of repeated transmissions of a Msg 3. The method includes: A terminal device receives first information. The terminal device obtains first indication information based on a shared bit in the first information. The first indication information indicates a quantity of repeated transmissions of a third message Msg 3. The third message Msg 3 is a radio resource control RRC connection request in a random access procedure. The shared bit is shared by the first indication information and the first information. The terminal device determines the quantity of repeated transmissions of the third message based on the first indication information.

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: 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 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, 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.
