    Abstract: This application relates to the wireless communications field applied to, for example, a wireless local area network supporting the 802.11be standard. In an example method, an access point (AP) generates and sends a trigger frame. The trigger frame includes an uplink length field, a common information field and a user information field. The uplink length field is used to indicate lengths indicated by legacy signal (L-SIG) fields in a high efficient trigger based physical layer protocol data unit (HE TB PPDU) and an extremely high throughput physical layer protocol data unit (EHT PPDU), or the uplink length field is used to indicate a length indicated by an L-SIG field in an EHT PPDU. An uplink bandwidth field in the common information field and the user information field in the trigger frame jointly indicate an uplink bandwidth used for sending the EHT PPDU.

    Abstract: This application provides example communication methods and devices to improve wireless local area network (WLAN) communication efficiency. In an example method, an access point (AP) sends first indication information. The first indication information indicates a first resource unit (RU) of a station (STA). The AP sends second indication information. The second indication information indicates whether the STA is allowed to send a physical layer protocol data unit (PPDU) based on a part of the first RU, and when the second indication information indicates that the STA is allowed to send the PPDU based on the part of the first RU. The PPDU includes a low density parity check (LDPC) extra symbol segment. The AP receives a first PPDU. A second RU occupied by the first PPDU is the part of the first RU. The first PPDU includes the LDPC extra symbol segment.

    Abstract: A resource allocation method includes sending, by a first device, resource allocation information to a second device. The resource allocation information indicates a first virtual resource unit (VRU). The first VRU includes a plurality of contiguous subcarriers in a frequency domain. The resource allocation method also includes mapping, by the first device, the first VRU to a first physical resource unit (PRU) based on a mapping relationship. The resource allocation method further includes transmitting data on the first PRU. A plurality of subcarriers included in the first PRU are noncontiguous in the frequency domain.

    Abstract: This application describes resource unit indication methods, access points, and stations. In an example method, a resource unit allocation subfield in a trigger frame includes a frequency band range indication and a resource unit indication. The resource unit indication is used to indicate a multi-resource unit (MRU) allocated to a station. The frequency band range indication is used to indicate a frequency band range in which a resource unit (RU) in the MRU is located. For example, the frequency band range indication is used to indicate 80 MHz in which a smallest RU in the MRU is located.

    Abstract: Embodiments of this application provide a communication method applied to a multi-link device in a wireless local area network WLAN and a related apparatus. The method includes: A reporting AP sends a management frame to a station. The reporting AP belongs to a first AP MLD, and belongs to a multiple BSSID set. The management frame includes MLD information. The MLD information carries, by using different types of MLD elements and a multiple BSSID element, for example, information about another AP in the MLD to which the AP belongs, information about the multiple BSSID set to which the AP belongs, and information about an AP in a multiple BSSID set including the another AP in the MLD to which the AP belongs. The station obtains information about the reporting AP and other information about a reported AP based on the management frame.
