    Abstract: A terminal is disclosed that includes a receiver that receives, via higher layer signaling, configuration information indicating a first resource for interference measurement, a second resource of non-zero power (NZP) channel state information reference signal (CSI-RS) for interference measurement, and a third resource of NZP CSI-RS for channel measurement. The terminal also includes a processor that performs interference measurement by using the first resource or the second resource, and performs channel measurement by using the third resource. The configuration information indicates a plurality of combinations of a third resource candidate and at least one of a first resource candidate and a second resource candidate. The processor uses, for measurement, a combination indicated by downlink control information among the plurality of combinations. In other aspects, a radio communication method, a base station, and a system are also disclosed.

    IPC: H04L5/00

    Abstract: A terminal according to one aspect of the present disclosure includes: a control section that determines one operation from a plurality of operations including a first operation of receiving a plurality of first reference signals in a cell and a second operation of receiving a plurality of second reference signals in the cell; and a receiving section that receives at least one of the plurality of first reference signals and the plurality of second reference signals, according to the one operation. The number of the plurality of second reference signals is larger than the number of the plurality of first reference signals. According to one aspect of the present disclosure, coverage can be improved in consideration of overhead.
