Abstract
A method, a device and a system for indicating terminal specific Demodulation Reference Signal (DMRS) are provided by the invention. The method includes that: a network side creates signal indicating information, and sends the created signal indicating information to a terminal (S501); the terminal, according to Transmission Block (TB) indicating information of the TB and multiple bits control information which are included in the signal indicating information, confirms DMRS pattern information, antenna port information and a scrambling ID of a reference signal sequence (S502) allocated for itself. The method, the device and the system provide by the invention, compared to the prior art, reduce signaling overhead which indicates the terminal specific DMRS, thus reducing resources waste of the system.
