1. An apparatus comprising:
processing circuitry configured to
acquire scheduling information from another apparatus;
measure a first reference signal non-zero-power (NZP) CSI-RS received from the serving base stations for channel measurement;
measure a second reference signal CSR-RS received for interference measurement; and
feed back channel status information including a channel quality indicator (CQI), which is based on a ratio of PDSCH energy per resource element (EPRE) to CSI-RS EPRE,
wherein the CQI is reported for each sub-band when a certain condition concerning a data signal is satisfied.
