Abstract:
In an LTE-A system, there is a problem that it is difficult to perform stable communication in a case where there is a time when another system occupies an unlicensed band being used. There is provided a base station apparatus that communicates with a terminal device in a second frequency band different from a first frequency band capable of being used as a dedicated frequency band. The base station apparatus includes: a wireless transmission unit that transmits data or control information to the terminal device; and a wireless reception unit that receives data or control information transmitted from the terminal device. The wireless transmission unit transmits data to the terminal device, and the wireless reception unit performs a process of receiving ACK/NACK transmitted from the terminal device in a subframe of an initial uplink after communication of another system is ended in a case where the other system performs the communication in the second frequency band at a reception timing of the ACK/NACK of the data transmission.

Claim (Index 3):
A communication method for a base station apparatus configured to communicate with a terminal apparatus in a first frequency band and a second frequency band, the second frequency band being an unlicensed frequency band, the communication method comprising the steps of:\n performing carrier sense in the second frequency band; and transmitting a first downlink signal and a second downlink signal, wherein transmitting the first downlink signal in at least a first slot on the first frequency band, and in a case of determining that communication is idle in the second frequency band, transmiting the second downlink signal on the second frequency band for a period of time, the period of time being equal to or less than a prescribed time, and transmitting the second downlink signal in a second slot on the second frequency band after the carrier sense.
