Claim 2:
3. A base station comprising:
a transmitter that transmits a first downlink control information for use in scheduling a downlink shared channel, and a second downlink control information for use in triggering a channel state information (CSI) reference signal (CSI-RS); and
a processor that, when the second downlink control information indicates a resource of the CSI-RS, performs a control so as not to use the resource of the CSI-RS for the downlink shared channel,
wherein the processor configures, by a radio resource control (RRC) signaling, a plurality of candidates of the resource indicated by the second downlink control information, and
wherein the plurality of candidates each contains an index, the index corresponding to a code point of a bit field included in the second downlink control information, and the processor indicates the resource by using the code point.
