Abstract: This application provides a resource unit indication method, an access point, and a station. In the 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 an MRU allocated to a station. The frequency band range indication is used to indicate a frequency band range in which an 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. In this way, the frequency band range indication indicates a frequency band range related to the MRU, and can further carry more information, for example, the frequency band range in which the smallest RU is located. It may be learned that this application may be applied to 802.11ax, 802.11be, and a future Wi-Fi system.

Abstract: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

Abstract: This application is applied to a wireless local area network supporting 802.11, to an NDPA frame transmission method and apparatus. The method includes: A beamformer (for example, an AP) generates and sends a universal NDPA frame, where an NDPA variant field (namely, B0 and B1 in a sounding dialog token field) included in the universal NDPA frame is set to any one of 00, 01, 10, and 11, and every two octets following the sounding dialog token field in the universal NDPA frame include one AID 11 or one disambiguation bit. If the AID 11 is in a station information field, the AID 11 is less than or equal to 2007; or if the AID 11 is in an extended common field, the AID 11 is greater than 2007. The disambiguation bit is forcibly set to 1. Embodiments of this application prevent an STA of an earlier version from misreading.
