The present invention relates to a terminal apparatus and a base station apparatus that enable efficient communication. To perform efficient uplink transmission by using a non-allocated frequency band or a shared frequency band. A terminal apparatus includes a reception unit configured to receive a message of terminal capability enquiry and a transmission unit that transmits terminal capability information in a case that the message has been received. In a case that the terminal capability information includes first information indicating that uplink LAA is supported, the transmission unit transmits a first PUSCH of a first resource allocation type or a second resource allocation type in a cell that is other than an LAA secondary cell, whereas in the LAA secondary cell, transmits a second PUSCH of a third resource allocation type.
