Method, related device and storage medium for displaying transmission configuration of DMRS port

摘要

The present application discloses a method, a related apparatus and a storage medium for indicating a transmission configuration of a DMRS port. In the method, the network-side device configures at least two DMRS ports for the terminal according to the mapping relationship between the required TCI state and the DMRS CDM group - the at least two DMRS ports belong to different CDM groups, different CDMs The number of DMRS ports included in a group is different -; and transmitting the DCI to the terminal, wherein the DCI includes a DMRS port index value, the DMRS port index value is a predefined index value in the DMRS port allocation table, and the DMRS port index value is a DMRS port assigned to the terminal. It is configured to indicate the set, the number of CDM groups without data, the number of front-load DMRS symbols, and the mapping relationship. The method supports dynamic adjustment of the number of DMRS ports corresponding to different TCI states, so that the flexibility of NC-JT is improved.
