Claim 2:
3. A base station apparatus that is a first base station apparatus comprising:
a transmission unit that transmits, to a terminal, a message requesting a report of capability of the terminal;
a reception unit that receives, from the terminal, a message reporting the capability of the terminal; and
a control unit that transmits a first signal transmitted from the first base station apparatus and a second signal transmitted from a second base station apparatus, within a maximum receive timing difference applied to a band combination included in the message reporting the capability of the terminal,
wherein the band combination includes a combination of a band of the first signal and a band of the second signal, and a radio access technology for the first signal differs from a radio access technology for the second signal, and
wherein a receive timing difference that is to be applied to the same bands is applied to the combination of the band of the first signal and the band of the second signal, as the maximum receive timing difference.
