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: 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: 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: 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.
