Abstract
The disclosure discloses a method of indicating channel state information reference signal (CSI-RS), comprising: when transmitting a CSI-RS via a downlink pilot time slot (DwPTS), generating, by a base station, a radio resource control (RRC) signaling indicative of a CSI-RS resource configuration state; and transmitting, by a base station, the RRC signaling to user equipment (UE); wherein the step of generating the RRC signaling indicative of the CSI-RS resource configuration state includes configuring a first field of the RRC signaling to be a special time slot, and configuring a second field of the RRC signaling to be a CSI-RS pattern in the special time slot; the configured special time slot is configured to instruct the UE satisfying a predefined condition to obtain the CSI-RS pattern indicated in the second field; the first field indicates a CSI-RS subframe configuration state; and the second field indicates a CSI-RS configuration of channel state information. The disclosure also discloses a base station and UE.
