Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. The rotor includes a hub that is capable of being supported by a shaft that extends along an axis, a plurality of laminations, and a plurality of wire windings supported by the plurality of laminations. The method further includes using the magnetic resonance parameter to determine a temperature differential in the portion of the body and using the temperature differential to determine a metabolic rate of the portion of the body. A peak luminance value of an individual pixel is generated in response to a peak luminance value of luminance values of pixels, spatially corresponding to the individual pixel and present in images comprising the plurality of temporally sequential individual difference images. The bottom belt moves in a continuous clockwise rotation, while the upper belt moves in counterclockwise rotation.
