Abstract: A terminal device includes: a higher layer processing unit configured to set at least one first RAT and at least one second RAT by signaling of a higher layer from the base station device; and a receiving unit configured to receive a transmission signal in the first RAT and a transmission signal in the second RAT. The transmission signal in the first RAT is mapped to a resource element configured on a basis of one physical parameter for each sub frame. The transmission signal in the second RAT is mapped to a resource element configured on a basis of one or more physical parameters for each sub frame and is mapped to a resource element configured on a basis of one physical parameter in a predetermined resource included in each of the sub frames.

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 perform one or more SPDCCH settings through signaling of a higher layer from the base station device; and a receiving unit configured to monitor an SPDCCH transmitted on a basis of an extended sub frame of a smaller number of symbols than a number of symbols corresponding to a sub frame and a resource block set by the SPDCCH setting on a basis of the SPDCCH setting. The SPDCCH is transmitted through one or more control channel elements. The control channel element is constituted by a plurality of resource element groups. In each of resource block pairs set by the SPDCCH setting, the resource element group is specified in association with a symbol in the resource block pair.
