1. A reference signal transmission method, comprising:
determining, by a first communication apparatus, a first transmission parameter in at least two transmission parameters, wherein any two of the at least two transmission parameters are different, and the first transmission parameter is used to determine a first transmission resource for a first reference signal, wherein the first transmission parameter comprises a resource offset indicating a time domain difference between a start transmission resource unit for the first reference signal in a resource cluster and a resource unit with a smallest sequence number in the resource cluster; and
sending, by the first communication apparatus, the first reference signal to a second communication apparatus on the first transmission resource.
