Abstract
There are provided a base station apparatus, a terminal apparatus, and a communication method which are capable of realizing a LTE-A system with improved throughput by performing a CA technology including an unlicensed band while suppressing interference from an existing system. A base station apparatus according to the present invention, which is included in a communication system that applies a communication scheme applied to a first frequency band capable of being used as a dedicated frequency band to a second frequency band different from the first frequency band and is capable of communicating with a terminal apparatus by using the second frequency band and the second frequency band. The base station apparatus: adds at least signal null periods to a frame of a second signal transmitted using the second frequency band; and sets a frame length of a signal frame included in the frame of the second signal transmitted using the second frequency band to be less than a frame length of a signal frame included in the frame of the first signal transmitted using the first frequency band.
