Abstract
Provided is an integrated circuit that calculates a power headroom (PHR) and that can preclude the recognition mismatch in which the reference formats of different UL grants are recognized between a wireless communication terminal apparatus and a wireless communication base station apparatus. For the PHR calculation of a PUSCH in a CC in which no UL grant is present, a UL grant, which was used for calculating the PHR in another CC having the same subframe number as the PUSCH, is used. For example, as to a subframe number=#1, the UL grant of CC #0 is used for calculating the PHR of CC #2 in which no UL grant is present.
