MOBILE STATION APPARATUS, BASE STATION APPARATUS, COMMUNICATION METHOD AND INTEGRATED CIRCUIT

摘要

In a wireless communication system in which a base station communicates with a terminal, the base station efficiently notifies of control information for the terminal. A base station apparatus maps an EPDCCH to any of candidates of the EPDCCH included in each of a first EPDCCH set and a second EPDCCH set which are configured by RRC signaling, and a mobile station apparatus monitors the candidate of the EPDCCH. The candidate of EPDCCH is determined at least based on the number of resource elements satisfying a predetermined criterion in one of physical resource block pairs that are configured for EPDCCH transmission in the first EPDCCH set.
