Title:
BASE STATION DEVICE, MOBILE STATION DEVICE, COMMUNICATION METHOD, INTEGRATED CIRCUIT, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/111658
Kind Code:
A1
Abstract:
The present invention enables the efficient transmission/reception of a signal containing control information between a base station device and a mobile station device. To achieve this, the present invention is characterized by being provided with: a reception unit that receives an enhanced physical control channel from the base station device; a setting unit that is configured in a manner so as to be able to set one of a plurality of ranges possible for M, which is the number of first elements configuring the enhanced physical control channel, using at least the format of downlink control information contained in the received enhanced physical control channel; and a monitoring unit that monitors a search region at which there is the possibility of the enhanced physical control channel specified by the set range possible for M being disposed.
