Terminal device, base station device, transmission method and reception method
Abstract:
The present disclosure enables dynamic switching to a frame format different from the UL-DL configuration set by an SIB, and in particular switching to a downlink communication subframe from an uplink communication subframe, while also enabling effective utilization of downlink communication subframes. A base station uses “UL/DL communication subframe switching information” included in a DCI sent by a downlink communication subframe to instruct a terminal whether or not to perform uplink communication to a DCI using one or more uplink-specific communication subframes, and also gives instructions whether to perform uplink communication or downlink communication on an uplink communication subframe switchable to a downlink communication subframe.
