TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

摘要

A first UL-DL setting set by a common RRC message is set. A determination is made, on the basis of whether or not a subframe is a prescribed special subframe in the first UL-DL setting, as to whether or not the number of extension control channel elements in one extension physical downlink control channel set of the subframe should be set to 0 when an index to an uplink control channel resource is determined. A second UL-DL setting indicated by downlink control information transmitted by a physical downlink control channel is set. When the second UL-DL setting is set, a determination is made on the basis of whether or not the subframe is a prescribed special subframe in the second UL-DL setting.
