Abstract: UEs each monitor a search space in multiple CORSETs and appropriately detect a DCI. In a base station (100), a DCI generator (102) selects one of multiple cases each indicating a combination of CORSETs to be monitored by a terminal (200) among multiple control channel regions (CORSETs). A transmitter (106) indicates, by higher-layer signaling, configuration information indicating the multiple cases, and indicates the selected case by dynamic signaling.

Abstract: The present disclosure aims at allowing a demodulation reference signal (DMRS) pattern suitable for a terminal to be selected from among a plurality of DMRS patterns including Legacy DMRS and Reduced DMRS. Disclosed is a terminal including: reception section 21 that receives uplink control information; control section 23 that determines a specific mapping pattern from among a plurality of mapping patterns for an uplink DMRS on the basis of the control information; and DMRS generating section 24 that generates a DMRS according to the specific mapping pattern.

Abstract: Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

Abstract: The present invention achieves an improvement in channel estimation accuracy using a reference signal. This terminal comprises: a control circuit for setting a first upper limit value of a frequency interval at which a first reference signal is placed in a first bandwidth such that the first upper limit value is smaller than a second upper limit value of a frequency interval at which a second reference signal is placed in a second bandwidth wider than the first bandwidth; and a transmission circuit for transmitting the first reference signal on the basis of the first upper limit value.

Abstract: Provided is a terminal capable of improving utilization efficiency of an uplink resource in an unlicensed band. In a terminal (200), a transmission control unit (206) sets, in accordance with at least one of a data size and retransmission of uplink data, a first end position of a time resource which is set for the uplink data to a second end position. A transmission unit (210) transmits the uplink data on the basis of the second end position.

Abstract: Provided is a terminal capable of appropriately disposing a reference signal. In the terminal (200), a reception unit (201) receives a downlink signal, a DCI reception unit (203) monitors, in the downlink signal, a candidate position of a control channel, and detects control information addressed to the terminal. The number of times the candidate position of a first control channel is monitored is less than the number of times the candidate position of a second control channel is monitored.

Abstract: This invention is a transmission device capable of enhancing the reception characteristics of a terminal when employing transmit diversity using two antenna ports in an ePDCCH. In a base station (100) that transmits a reference signal to a terminal (200) using two antenna ports, a setting unit (102), on the basis of the reception quality of the terminal, sets as the aforementioned two antenna ports either a first antenna port pair for which DMRS (reference signals) do not undergo mutual code multiplexing, or a second antenna port pair for which the DMRS do undergo code multiplexing. A transmitter (109) transmits the DMRS from the two antenna ports set in the setting unit (102).
