Abstract: A first device sends a first message to a second device, where the first message indicates to the second device to hop to different channels at different times to send radio signals. The frequency bandwidth ranges of any two channels do not completely overlap, and the frequency bandwidth range of each channel is within a total frequency bandwidth range supported by the first device. The first device separately receives the radio signals that are sent by the second device on different channels at different times. The radio signals reach the first device after being reflected by an intermediate object. The first device measures the state information of the intermediate object based on the physical characteristics of the different radio signals that are separately received.

Abstract: Embodiments of this application disclose a communication method between multi-link devices and an apparatus, and relate to the field of communications technologies, to reduce power consumption of a station multi-link device. A specific solution is as follows: A multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.
