1. An electronic device comprising:
processing circuitry configured to,
calculate an intra metric based on cross correlation of a plurality of first reference signal symbols (RSs) included in a first precoding resource block group (PRG) to which a target resource element (RE) belongs,
calculate an inter metric based on cross correlation of one or more second RSs and one or more among the plurality of first RSs, the one or more second RSs being included in a second PRG adjacent to the first PRG along a frequency axis of a physical channel, the one or more second RSs being in proximity to the target RE, and the physical channel being received from a base station,
compare a first ratio between the intra metric and the inter metric with a threshold ratio to obtain a comparison result, and
determine a channel estimation mode with respect to the target RE based on the comparison result.
