1. A signal transmission method, wherein the method comprises:
obtaining, by a first detection apparatus, a first moment, wherein the first moment is a start moment of a first time unit, and the first time unit is used for the first detection apparatus to send a first signal; and
sending, by the first detection apparatus, the first signal based on a first periodicity, wherein:
the first signal is used to indicate sending resource information of a detection signal,
the first time unit is further used for a second detection apparatus to receive the first signal,
the first periodicity is a periodicity in which the second detection apparatus receives the first signal, and
the first periodicity is a common multiple of a second periodicity and a third periodicity, wherein the second periodicity is a periodicity in which the first detection apparatus sends the detection signal, and the third periodicity is a periodicity in which the second detection apparatus sends a second detection signal.
