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 receiving unit configured to monitor a first PDCCH that is transmitted on a basis of a sub frame which is defined by a predetermined number of symbols, and a second PDCCH that is transmitted on a basis of an extended sub frame which has a smaller number of symbols than a number of symbols corresponding to the sub frame and a resource block which is set according to a second PDCCH setting. A first PDSCH allocated by the first PDCCH is mapped on a basis of a resource block pair corresponding to the number of symbols of the sub frame. A second PDSCH allocated by the second PDCCH is mapped on a basis of a sub resource block corresponding to the number of symbols of the extended sub frame.

Abstract: Provided is a mechanism capable of improving the transmission efficiency of the entire system in a case where dynamic resource sharing is performed.
A terminal device includes: an acquisition unit that acquires first control information and second control information provided in notification from a base station device; and a reception processing unit that performs reception processing of a first data channel scheduled to a first resource, and a reference signal for demodulating the first data channel, on the basis of the first control information, in which the reception processing unit performs the reception processing of the first data channel mapped to a resource other than a second resource that is a part of the first resource in the first resource on the basis of the second control information on the assumption that the reference signal is mapped to the first resource including the second resource.-
