1. A user equipment comprising:
a receiver, which, in operation, receives a plurality of channel state information-reference signals (CSI-RSs) based on one or more CSI-RS configurations; and
circuitry, which, in operation, calculates a channel quality indicator (CQI) based on the plurality of CSI-RSs,
wherein two or more CSI-RS configurations are used for more than eight CSI-RS ports, and
wherein sequences of the plurality of CSI-RSs are generated by using a CSI-RS ID which is indicated by a higher layer signaling and which is different from a cell ID.
