Abstract
A reference signal sending and receiving method, an access network device, and a terminal device are provided. The method includes: determining, by an access network device, a demodulation reference signal DMRS pattern corresponding to an antenna port; sending, by the access network device, first indication information to a terminal device, where the first indication information indicates the DMRS pattern corresponding to the antenna port; and sending, by the access network device, a DMRS to the terminal device through the antenna port on a resource corresponding to the DMRS pattern. According to the embodiments of this application, the resource for transmitting the DMRS corresponding to the antenna port can be flexibly indicated by the DMRS pattern.
