Abstract: This application describes resource unit indication methods, access points, and a 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 multiple 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. The described techniques can be applied to, for example, 802.11ax, 802.11be, and future Wi-Fi systems.
