Abstract: A method and apparatus for determining an information transmission position. The method includes upon receiving at least one control information DCI sent by a network side, a terminal determines a reference transmission position according to a predefined rule, the preset rule being predefined information or configured by high-layer signaling, and then determines, according to the reference transmission position, a transmission parameter of a first physical channel or first physical information. In this way, a transmission parameter of a first physical channel or first physical information can be determined according to a determined reference transmission position, thus avoiding the problem of a reception failure of transmitted data information or first physical information due to incorrect determination of a transmission position of the first physical channel or first physical information by a terminal, and ensuring the reliability of reception of the transmitted data information by the terminal.

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.
