    Abstract: Method and device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain one or more CSI-RS configuration codes. The CSI-RS configuration codes are sent to a terminal device. The terminal device determines, based on CSI-RS configuration codes, CSI-RS configuration information such as a quantity of antenna ports for transmitting a CSI-RS, a CSI-RS pattern, a CSI-RS period and an offset corresponding to the CSI-RS period.

    Abstract: A method and a device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain a CSI-RS configuration information code. A mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information is stored. A CSI-RS configuration information code corresponding to CSI-RS configuration information to be notified is searched in the stored mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information. The searched CSI-RS configuration information code is sent to a user equipment (UE), so that the UE determines CSI-RS configuration information according to the received CSI-RS configuration information code and the mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information.
