TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

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 includes: a higher layer processing unit configured to set an STTI channel setting through signaling of a higher layer from the base station device; and a receiving unit configured to receive a first PDSCH in a case in which the STTI channel setting is not set and receive a second PDSCH in a case in which the STTI channel setting is set. The first PDCCH is mapped to one or more resource blocks, and the second PDCCH is mapped to one or more sub resource blocks defined in accordance with a smaller number of symbols than a number of symbols corresponding to a resource block.
