Communication device and method of controlling same
First Claim
1. A communication device that measures a valid received power even when a subcarrier offset of a measurement bandwidth is different from a subcarrier bandwidth of a cell bandwidth, the communication device comprising:
- a transceiver that receives first channel state information from a first Base Station (BS) and receives a plurality of Resource Blocks (RBs) from a second BS;
a memory that stores the first channel state information and second channel state information, the second channel state information including an alternative index determined through a modular operation based on a value of an index included in the first channel state information; and
a processor electrically connected to the transceiver and the memory,wherein the processor;
measures a first received power of the plurality of RBs using the index included in the first channel state information,compares the value of the index included in the first channel state information to a predetermined value,measures another received power of the plurality of RBs from the second BS by using the alternative index included in the second channel state information, based on the comparison of the value of the index included in the first channel state information to the predetermined value, anddetermines a measured received power having a highest strength as the valid received power, andwherein the index and the alternative index include subcarrier offset (k) information on the plurality of RBs.

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.
