Method of indicating csi-rs, base station and user equipment

A Channel State Information-Reference Signal (CSI-RS) indication method, applied to User Equipment (UE), the method comprising:

• when a CSI-RS is transmitted through a Downlink Pilot Time Slot (DwPTS), receiving Radio Resource Control (RRC) signaling that indicates a CSI-RS resource configuration;
• acquiring a first field in the RRC signaling;
• and
• when the first field is determined to indicate a special slot and the UE meets a preset condition, determining a CSI-RS pattern in the special slot according to a CSI-RS pattern indicated by a second field in the RRC signaling,
• wherein the first field indicates a CSI-RS subframe configuration and the second field indicates a CSI-RS configuration.

A base station, comprising a processor and one or more units stored on a memory and executable by the processor, the one or more units comprising a generation unit and a sending unit, wherein

• the generation unit is configured to, when a Channel State Information-Reference Signal (CSI-RS) is transmitted through a Downlink Pilot Time Slot (DwPTS), generate Radio Resource Control (RRC) signaling that indicates a CSI-RS resource configuration;
• and
• the sending unit is configured to send the RRC signaling to User Equipment (UE), wherein,
• when the RRC signaling that indicates the CSI-RS resource configuration is generated, the generation unit configures a first field in the RRC signaling to indicate a special slot and configures a second field in the RRC signaling to indicate a CSI-RS pattern in the special slot;
• the configured special slot is configured to indicate the UE meeting a preset condition to acquire the CSI-RS pattern indicated by the second field;
• and
• the first field indicates a CSI-RS subframe configuration, and the second field indicates a CSI-RS configuration.

User Equipment (UE), comprising a processor and one or more units stored on a memory and executable by the processor, the one or more units comprises:

• a receiving unit, a first acquisition unit and a second acquisition unit, wherein
• the receiving unit is configured to, when a Channel State Information-Reference Signal (CSI-RS) is transmitted through a Downlink Pilot Time Slot (DwPTS), receive Radio Resource Control (RRC) signaling that indicates a CSI-RS resource configuration;
• the first acquisition unit is configured to acquire a first field in the RRC signaling;
• and
• the second acquisition unit is configured to, when the first field is determined to indicate a special slot and the UE meets a preset condition, determine a CSI-RS pattern in the special slot according to a CSI-RS pattern indicated by a second field in the RRC signaling,
• the first field indicates a CSI-RS subframe configuration and the second field indicates a CSI-RS configuration.
