Abstract: A demodulation reference signal (DMRS) indicating method, a DMRS receiving method, and an apparatus are described. A transmit end determines, from a plurality of groups of demodulation reference signal DMRS configuration information, DMRS configuration information corresponding to a current DMRS transmission scheme. The transmit end obtains DMRS indication information based on the DMRS configuration information, where each group of DMRS configuration information includes a plurality of pieces of DMRSs configuration information. The transmit end sends the DMRS indication information. The described method and the apparatus are implemented to match a plurality of New Radio (NR) scenarios. The described operations can satisfy a requirement for transmitting more layers of data and reduce indication overheads.
