Provided by the present application is a method for sending and receiving instructions, comprising: receiving instruction information generated according to a demodulation reference signal (DMRS) port configuration table corresponding to the pattern type of a DMRS, the DMRS port configuration table comprising multiple rows of DMRS configurations; and determining, according to the instruction information, a DMRS port and the number of CDM antenna port groups of the DMRS which are not used for data transmission, wherein the multiple rows of DMRS configurations comprise one or multiple rows of DMRS configurations suitable for multi-user scheduling, the number of configured CDM antenna port groups being greater than or equal to 2, the configured DMRS ports being from at least two of the CDM antenna port groups, and at least one CDM antenna port group among the CDM antenna port groups of which there are two or more having no quasi-co-location relationship with the other CDM antenna port groups. Thus, a terminal device may be configured to expand to a DMRS configuration solution in more scenarios, thereby reducing the limitations of DMRS configuration.
