1. A method for selecting Demodulation Reference Signal (DMRS) pattern information, comprising:

  • selecting, by a base station, DMRS pattern information on the basis of a preset first rule, and informing a terminal of the selected DMRS pattern information; and

    sending, by the base station, a DMRS to the terminal according to the selected DMRS pattern information;

    wherein the first rule at least comprises one of the followings;

    a Modulation and Coding Scheme (MCS), a size of continuous Physical Resource Block (PRB) pairs allocated for the terminal, a size of Physical Resource Group (PRG), a mode of continuously scheduling sub-frames in time domain or a number of the continuously scheduled sub-frames, a system bandwidth, a carrier index, a carrier type, a carrier frequency, a start position of an Orthogonal Frequency Division Multiplexing (OFDM) symbol of a Physical Downlink Shared Channel (PDSCH), a start position of an OFDM symbol of an Enhanced Physical Downlink Control Channel (EPDCCH), a PDSCH RE Mapping and Quasi-Co-Location Indicator (PQI) based on a PDSCH, high layer signalling configuration based on a sub-frame cluster and a sub-frame type.
