Abstract
Disclosed in the present application are a method for transmission configuration indication (TCI) of a DMRS port and a related apparatus, and a storage medium. In the method, a network side device configures at least two DMRS ports for a terminal according to the correspondence between required TCI states and DMRS CDM groups, the at least two DMRS ports belonging to different CDM groups, and the different CDM groups comprising different numbers of DMRS ports; and sends DCI to the terminal, the DCI comprising a DMRS port index value, the DMRS port index value being an index value pre-defined in a DMRS port allocation table, and the DMRS port index value being used for indicating a DMRS port set allocated to the terminal, the number of CDM groups without data, and the number of preamble DMRS symbols, and being used for indicating the correspondence.
