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. A method includes receiving, via a transceiver, first channel state information including a first index associated with first subcarrier offset information from a first Base Station (BS); receiving, via the transceiver, a plurality of Resource Blocks (RBs) from a second BS; configuring a second index associated with the plurality of RBs, instead of the first index, when the first index is different from the second index; measuring a received power based on the plurality of RBs from the second BS by using the second index; and identifying the measured received power as a valid received power.
