Abstract
A positioning signal sending method and apparatus are provided. A first signal is generated, where duration of a first rising edge of the first signal is less than duration of a first falling edge, the duration of the first rising edge is duration of a rising edge of a main lobe waveform of the first signal, and the duration of the first falling edge is duration of a falling edge of the main lobe waveform of the first signal; and the first signal is sent. In embodiments of this application, rising time of a main lobe waveform of a signal generated is short, and shorter rising time of the main lobe waveform is more conducive to distinguishing two adjacent paths or identifying a first arrival path of a received signal.
