Abstract
A method, an apparatus and a system for configuring a Demodulation Reference Signal (DMRS) are disclosed in the present invention. The method includes: receiving a DMRS indication index transmitted from a network side; determining at least one port used for the local transmission of the DMRS; acquiring the predetermined DMRS configuration parameters corresponding to the DMRS indication index and the at least one port, and configuring, according to the DMRS configuration parameters, the DMRS to be transmitted from the at least one port. Therefore, the terminal can implement the configuration of the DMRS without reloading the corresponding configuration information. Thus, the implementation complexity of the DMRS configuration flow is decreased, and the operation load of the terminal is also reduced.
