Example sensing
signal transmission methods and related apparatuses are provided. One example method includes determining, by a first apparatus, a first numerology indicating a length of a first
time domain symbol that is in a first slot and that is for carrying a sensing
signal. The first apparatus determines a second numerology, where the second numerology indicates a length of a second
time domain symbol that is in the first slot and that is for carrying a communication
signal, and the length of the first
time domain symbol and the length of the second time domain symbol are in an integer multiple relationship. The first apparatus performs at least one of sending the sensing signal based on the first numerology, sending the communication signal based on the second numerology, receiving the sensing signal based on the first numerology, or receiving the communication signal based on the second numerology.
