USER TERMINAL, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention suppresses increases in blind decoding frequency in cross-carrier scheduling in expansion carrier aggregation. According to the present invention, when cross-carrier scheduling is established by a wireless base station and the number of component carriers to be scheduled from among component carriers at a scheduling source has exceeded a prescribed value, a user terminal that can communicate with the wireless base station using six or more component carriers determines a user-terminal-specific search space candidate for each component carrier on the basis of upper-layer signaling that is established such that an arbitrary carrier indicator field (CIF) value corresponds to an arbitrary cell index.
