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: 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).

Abstract: A self-contained operation using a time-unit configuration taking into consideration HARQ processes is performed. In base station, transmission section transmits a downlink signal in a downlink transmission region in a time unit composed of the downlink transmission region, an uplink transmission region, and a gap interval that is a switching point from the downlink transmission region to the uplink transmission region; and reception section receives an uplink signal in the uplink transmission region in the time unit. Each time unit includes the downlink transmission region and the uplink transmission region for each of HARQ processes.

Abstract: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit (101) in base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit (103) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

Abstract: A terminal includes circuitry and a transmitter. The circuitry, in operation, determines a first transmission power for a first uplink signal and a second transmission power for a second uplink signal by prioritizing allocation of a transmission power to the second transmission power for the second uplink signal, responsive to, in a first transmission time interval (TTI) where the first uplink signal is transmitted, the second uplink signal being transmitted in a second TTI that is shorter than the first TTI. The transmitter, in operation, transmits the first uplink signal with the determined first transmission power and transmits the second uplink signal with the determined second transmission power.

Abstract: Provided is a terminal that can appropriately transmit an uplink signal. In a terminal (200), a control unit (211) determines a processing mode with respect to uplink data and uplink control information according to a requirement for at least one of uplink data and uplink control information when transmission of an uplink data channel that includes the uplink data and transmission of an uplink control channel that includes the uplink control information temporally overlap. A transmission unit (218) transmits the at least one of the uplink data and the uplink control information on the basis of the determined processing mode.
