Channel estimates of first pilot tones are detected, which have a predetermined subcarrier spacing or less from the second resource allocation block, channel estimates of second pilot tones are detected; and which have a predetermined subcarrier spacing or less from the first resource allocation block. The channel estimates of the first and second pilot tones are updated, and channel estimation is then performed using the updated channel estimates.
