FIELD: radio engineering, communication.SUBSTANCE: invention relates to a method, device and system for indicating a demodulation reference signal (DMRS) for a specific terminal. The method includes that: a network side generates signal indicating information, and sends the generated signal indicating information to a terminal (S501); the terminal, according to Transmission Block (TB) indicating information and multiple-bit control information which are included in the signal indicating information, confirms DMRS pattern information, antenna port information and a scrambling identifier of a reference signal sequence (S502) allocated for itself.EFFECT: reducing signalling overhead for indicating the DMRS for a specific terminal, thus reducing wastage of system resources.17 cl, 11 dwg, 6 tbl |
