Abstract
A terminal device (UE) includes a reception unit configured to monitor an enhanced physical downlink control channel (EPDCCH) on a Serving cell with frame structure type 3. In a case that the terminal device detects downlink control information (DCI) in a subframe, the terminal device assumes a configuration of OFDM symbols according to a field in the DCI in the subframe. The OFDM symbols are used for downlink transmission. A demodulation reference signal (DMRS) associated with the EPDCCH is mapped in the subframe according to the configuration of the OFDM symbols.
