The invention discloses a quasi co-located (QCL) indicator information indication method and device and is used for realizing diversity of reference signal types and reference signal configuration information indicated by QCL. The method comprises the steps that a base station generates the reference signal configuration information; the base station carries out quasi co-located (QCL) assumption on reference signals corresponding to at least two antenna ports in the reference signals according to the reference signal configuration information, thereby generating QCL indicator information; andthe base station sends the QCL indicator information to the terminal.
