Abstract: [Object] To provide a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other.[Solution] A terminal device that communicates with a base station device, including: a higher layer processing unit configured to perform SPDSCH setting through signaling of a higher layer from the base station device; and a receiving unit configured to receive a PDSCH in a case in which the SPDSCH setting is not performed and receive an SPDSCH in a case in which the SPDSCH setting is performed. The SPDSCH is mapped to any one of one or more SPDSCH candidates set on a basis of the SPDSCH setting. A number of symbols of a resource used for mapping of the SPDSCH is smaller than a number of symbols of a resource used for mapping of the PDSCH.
