Title:
TERMINAL DEVICE, BASE STATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/169005
Kind Code:
A1
Abstract:
[Problem] To provide a terminal device that can efficiently perform communication in a communication system in which a base station and a terminal device communicate with one another. [Solution] This terminal device comprises: an upper layer processing unit that sets one or more second PDCCH settings by upper layer signaling from the base station device; and a receiving unit that, if second PDCCH settings are not set, monitors only the shared search space in the first PDCCH and the search space unique to the terminal device, and if second PDCCH settings are set, monitors at least the search space unique to the terminal device in the second PDCCH. The first PDCCH is transmitted on the basis of a subframe defined by a predetermined number of symbols. The second PDCCH is transmitted on the basis of an expanded subframe having a fewer number of symbols than the number of symbols corresponding to the subframe, and a resource block set by the second PDCCH settings.
