Abstract: A method includes, in accordance with some implementations, sending, a measurement station, a trigger frame to a signal source station, where the trigger frame carries pilot format information, and the pilot format information is used to indicate a sending time point of a signal frame triggered by the trigger frame, a quantity of times for sending the signal frame, and a transmission mode of pilot information in the signal frame. The measurement station receives an illumination frame from the signal source station, where the illumination frame is the signal frame triggered by the trigger frame. The measurement station analyzes pilot information in the illumination frame to obtain sensing information in the illumination frame, where the sensing information is used to indicate physical information of an object surrounding the signal source station and the measurement station.

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.
