Abstract:
To provide a base station apparatus, a terminal apparatus, and a communication method capable of cell search with an accuracy meeting a required condition for each of the radio parameter sets. There are provided a radio reception unit configured to receive downlink signals in a frequency band, the frequency band being constituted by a region of a first radio parameter set and a region of a second radio parameter having a subcarrier spacing different from that of the first radio parameter set, and a synchronization detecting unit configured to establish synchronization with the base station apparatus in the frequency band. A synchronization signal sequence of the first radio parameter set is mapped to the region of the first radio parameter set, and a synchronization signal sequence of the second radio parameter set is mapped to the region of the second radio parameter set. The synchronization detecting unit detects synchronization with the base station apparatus in the frequency band by using the synchronization signal sequence of the first radio parameter set and the synchronization signal sequence of the second radio parameter set.

Claim (Index 9):
A base station apparatus for performing OFDM communication with a terminal apparatus, the base station apparatus comprising:\n a synchronization signal generation unit configured to generate a synchronization signal sequence of a first radio parameter set and a synchronization signal sequence of a second radio parameter set; a multiplexing unit configured to, in a frequency band constituted by a region of the first radio parameter set and a region of the second radio parameter set having a subcarrier spacing different from a subcarrier spacing of the first radio parameter set, map the synchronization signal sequence of the first radio parameter set to the region of the first radio parameter set and map the synchronization signal sequence of the second radio parameter set to the region of the second radio parameter set; a radio transmission unit configured to transmit the synchronization signal sequence of the first radio parameter set and the synchronization signal sequence of the second radio parameter set to the terminal apparatus; and a radio reception unit configured to receive an uplink signal from the terminal apparatus, wherein in a case that the radio reception unit receives information indicating that synchronization is established in any radio parameter set, the radio transmission unit transmits information on a synchronization signal sequence of other radio parameter set than the radio parameter set specified by the information indicating that the synchronization is established.
