Abstract
The present invention enables efficient transmission/reception of a signal including control information between a base station apparatus and a mobile station apparatus.
To achieve this, a mobile station apparatus of the present invention is a mobile station apparatus that communicates with a base station apparatus, and includes a receiver configured to receive an enhanced physical downlink control channel and specific information from the base station apparatus; a setting unit configured to be able to set, based on the specific information, one of a plurality of possible sets of M, M being the number of first elements that constitute the enhanced physical downlink control channel; and a monitoring unit configured to monitor a search region in which the enhanced physical downlink control channel obtained on the basis of the set possible set of M is possibly mapped.
