Summary:This application relates to the field of wireless communications technologies, and discloses a signal sending method. The method includes: mapping, onto a time frequency resource, a first signal that is in frequency domain and that corresponds to a subcarrier spacing parameter in a subcarrier spacing system parameter group, and generating a second signal that is in time domain and that corresponds to the first signal; and sending the second signal to a second network device. First signals corresponding to the different subcarrier spacing system parameters occupy a same quantity of subcarriers, and second signals corresponding to the different subcarrier spacing system parameters occupy a same time length T. In this way, when the second network device detects a specified signal in a signal sent by a first network device, impact of the quantity of subcarriers and the time domain length corresponding to the different subcarrier spacing system parameters may be ignored, thereby simplifying complexity of detecting the specified signal by the second network device, and improving communication efficiency of a wireless system.
