Abstract: The embodiments of the invention provide a method of configuring a channel state information reference signal (CSI-RS) transmitted on a pilot and a device utilizing the same. The method includes: a base station generates a signaling including configuration information of a CSI-RS; and the base station transmits the signaling including the configuration information of the CSI-RS; wherein the configuration information includes a CSI-RS port number, CSI-RS resource patterns and a CSI-RS subframe configuration; the CSI-RS resource patterns include at least one of the following: CSI-RS resource patterns transmitted on a normal downlink subframe and CSI-RS resource patterns transmitted on a downlink pilot time slot (DwPTS). The CSI-RS subframe configuration includes a CSI-RS subframe configuration transmitted on both the DwPTS and the normal downlink subframe. The embodiments resolve a complicated problem of transmitting CSI-RS in DwPTS in a CSI-RS transmission scenario, reducing complexity of transmitting CSI-RS in DwPTS.
