    Abstract: Apparatuses, methods, and systems of measuring received power are described, including apparatuses, methods, and systems which can measure received power, even when the subcarrier offset of the measurement bandwidth is different from the subcarrier bandwidth of the cell bandwidth. In one method, the first received power of a plurality of Resource Blocks (RBs) received from a second Base Station (BS) are measured based on first channel state information received from a first BS. Based on the determination whether a value of an index included in the first channel state information is larger than a predetermined value, at least one of second received power, third received power, and fourth received power of the plurality of RBs is measured by using second channel state information including an alternative index determined based on the first channel state information based on a result of the determination.
