Classification: CPC H | IPC H

Claim 2:
3. A base station comprising:
a processor that controls:
an indication of a resource by a first downlink control information for use in scheduling a downlink shared channel, and
an indication of a resource by a second downlink control information for use in triggering a channel state information (CSI) reference signal (CSI-RS); and

a transmitter that transmits at least one of the downlink shared channel and the CSI-RS,
wherein, when the downlink shared channel is scheduled to a resource corresponding to the CSI-RS, the processor performs a control the indication of the resource by the first downlink control information to receive the downlink shared channel in a terminal,
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.
