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 1):
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 base station apparatus comprising:\n CS determination circuitry configured to perform carrier sense in the second frequency band; and wireless transmission circuitry configured to transmit a first downlink signal and a second downlink signal, wherein the wireless transmission circuitry transmits the first downlink signal in at least a first slot on the first frequency band, and in a case where the CS determination circuitry determines that communication is idle in the second frequency band, the wireless transmission circuitry transmits 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 transmits the second downlink signal in a second slot on the second frequency band after the carrier sense.
