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 an information transmission method and a communication apparatus. The method includes: A first device sends TWT resource configuration information in a first BSS to a second device. The first device is located in the first BSS, the second device is located in a second BSS, and the first BSS and the second BSS at least partially overlap. According to the information transmission method provided in this application, TWT resource configuration information in a plurality of BSSs is shared among the plurality of BSSs in an OBSS scenario. Therefore, collision can be further avoided during data transmission in different BSSs in the OBSS scenario, thereby improving quality and assurance of data transmission between devices in the plurality of BSSs, and improving efficiency of data transmission in the OBSS scenario.
