Abstract: A sensing method and apparatus, to combine a sub-7 GHz frequency band and an mmWave frequency band for Wi-Fi sensing, and improve performance of sensing a Wi-Fi signal. The method includes: receiving a plurality of first communication data frames in the first frequency band and a plurality of second communication data frames in the second frequency band, where a frequency of the first frequency band is higher than a frequency of the second frequency band; and obtaining a plurality of pairs of communication data frames, where each of the plurality of pairs of communication data frames includes a first communication data frame in the first plurality of communication data frames and a second communication data frame in the second plurality of communication data frames, and a time difference between a first timestamp of the first communication data frame and a second timestamp of the second communication data frame falls within a preset threshold range.
