Abstract: A demodulation reference signal information determining method, and a terminal are provided. The demodulation reference signal information determining method includes: receiving first Demodulation Reference Signal (DMRS) indication information sent by a network side device. The method further includes determining DMRS information of a target DMRS based on the first DMRS indication information. Ports, belonging to a same Code Division Multiplexing (CDM) group, in the target DMRS are mapped based on a length-4 Frequency Division-Orthogonal Cover Code (FD-OCC) sequence. The DMRS information includes at least one of the following: the quantity of target CDM groups, port information of the target DMRS, or the quantity of front-load symbols. The target CDM group is a CDM group, not occupied by data, in a CDM group corresponding to the target DMRS.
