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.

Abstract: In a method for sending signals in network communications, an apparatus obtains a plurality of extended sequences, with each extended sequence comprising an original sequence and an additional sequence. In each extended sequence, the additional sequence is located before the original sequence, and the additional sequence includes last m codes of the original sequence. Alternatively, the additional sequence is located after the original sequence, and the additional sequence includes first n codes of the original sequence. The apparatus generates a plurality of target sequences based on the plurality of extended sequences and a security code corresponding to each extended sequence. The apparatus then generates a first impulse signal based on the plurality of target sequences, and sending the first impulse signal.
