Abstract
A Demodulation Reference Signal (DMRS) port indication method, device and a base station are disclosed. A provided DMRS port indication table covers all cases of transmission maximally supporting 8 layers, and 4 bits defined by DMRS port indication information may indicate all the cases in the DMRS port indication table in combination with single-codeword transmission and double-codeword transmission cases of a related standard, so that bit overhead of the DMRS port indication information may be reduced.
