Abstract: Provided in embodiments of the present invention are a method and device for transmitting control information. In an embodiment of the present invention, the method comprises: a base station determining to repeatedly transmit DCI; and the base station repeatedly causing the DCI to be carried on at least two PDCCHs used for repeated DCI transmission, and transmitting same. When a terminal is unable to successfully detect some of PDCCHs for repeated DCI transmission due to a blockage or interference, the terminal can still perform detection on the remaining PDCCHs to obtain DCI, thereby enhancing the reliability of DCI transmission.

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. The method supports dynamic adjustment of the numbers of DMRS ports corresponding to different TCI states, thereby improving the flexibility of NC-JT.

Abstract: Disclosed in the present application are a TCI indication method and apparatus, a base station, and a storage medium. The method comprises: when TCI in DCI configured by a base station for a UE corresponds to at least two TCI states, indicating a correspondence between a CDM group and a TCI state by mean of the DCI, wherein the CDM group is a CDM group to which a DMRS port allocated by the base station for the UE belongs. The described method is used to indicate the correspondence between each CDM group to which the DMRS port allocated for the UE belong to and the TCI state so as to support the dynamic adjustment of the number of DMRS ports corresponding to different TCI states, therefore improving the flexibility of NC-JT.

Abstract: Disclosed are a method and apparatus for transmitting an initial access signal, thus solving the existing problem wherein transmitting and detecting of synchronization signals cannot be applied to large-scale network coverage of a future communication system. The method comprises: determining at least one to-be-transmitted identification information of a synchronization block, the synchronization block comprising at least two components for transmitting an initial access signal, and different components occupying different time-frequency resources of the synchronization block; determining an initial access signal transmitted by each component in the synchronization block according to the identification information; and determining a time-frequency resource occupied by each component in the synchronization block and transmitting the initial access signal of the component on the time-frequency resource occupied by each component.
