摘要： The application relates to a method for antenna port indication. A terminal receives information indicating an antenna port set of a pilot from a base station. The antenna port set is used for a resource block (RB) set and the pilot is used for data demodulation. And the terminal determines the antenna port set based on the received information. By implementing the solution in the application, transmission resource utilization is improved.

摘要： Embodiments of this application provide a parameter determining method, a base station, and user equipment. The parameter determining method provided in this application includes: determining, by a base station, a first subcarrier spacing corresponding to UE; and notifying, by the base station, the UE of the first subcarrier spacing. In the embodiments of this application, the UE may accurately learn of, in a multi-subcarrier-spacing system, a subcarrier spacing used for data transmission, and then perform data transmission. This can effectively ensure that the UE performs a corresponding service, thereby meeting a corresponding service requirement.
