PROBLEM TO BE SOLVED: To provide a wireless communication device and wireless communication method with which the interpolation order for time region interpolation and frequency region interpolation can be changed depending on the degree of channel fluctuation. SOLUTION: The wireless communication device (100) is equipped with: a pilot channel estimation unit (30) that estimates channel estimation values from pilot symbols, channel statistics information estimation units (40, 50) that estimate channel statistics information pertaining to the degree of channel fluctuation in at least a time region or a frequency region, an interpolation region order determination unit (60) that determines the channel interpolation order for time regions and frequency regions, and an interpolation unit (70) that provides channel interpolation of the time regions and the frequency regions. The interpolation unit first executes the channel interpolation of a time region or a frequency region using the channel estimation values, and then executes the channel interpolation of the other type of region using the channel estimation values and the channel interpolation value obtained through the first channel interpolation according to the order determined by the interpolation region order decision unit.
