Abstract: A base station is disclosed that enables an efficient use of resources even when a TTI length is shortened. In this base station, a PDCCH section (103) generates one piece of downlink control information (DCI) containing control information for a plurality of first transmission time intervals (TTIs) each having a TTI length shorter than a second TTI, and a transmission section (107) transmits the DCI. Control information on retransmission processing for a data signal is configured for each of the plurality of first TTIs while control information other than the control information on the retransmission processing is configured in common among the plurality of first TTIs in the DCI.

Abstract: In an operation in a license-exempt band (unlicensed band), the present invention contributes to the provision of a mobile station, a base station, a transmission method and a receiving method which suitably transmit and receive a signal. The mobile station 200 includes: a transmission unit 205 which transmits an uplink signal; and a control unit 201 which, when a first number indicating a first resource amount that can be used in the transmission of the uplink signal includes a third number, which is different from a specific second number, as a prime factor, controls the transmission of a signal of a fourth number that does not include the third number as the prime factor by using a second resource.

Abstract: Provided is a base station that performs feedback with regard to data transmission. The base station includes a downlink feedback information (DFI) generation unit and a transmitter. On the basis of a resource allocation configuration that was configured by a terminal, the DFI generation unit determines a transmission method for feedback information that includes a response signal regarding uplink data. The transmitter transmits the feedback information on the basis of the transmission method.

Abstract: A terminal includes a receiver, which, in operation, receives time unit information related to an amount of an uplink time resource per a time unit, and receives a number of repetitions over a plurality of the time units, wherein the time unit includes a downlink time resource for a downlink signal and the uplink time resource for a response signal. The amount of the uplink time resource is expressed as a fixed number of consecutive symbols that remains the same number over the plurality of the time units over which the response signal is repeatedly transmitted. The terminal includes a transmitter, which, in operation, repeatedly transmits the response signal over the plurality of the time units.

Abstract: A reception processor receives the cell detection reference signals, each of the cell detection reference signals being transmitted from corresponding one of a plurality of cells. An RRM report generator generates measurement information indicating a measurement result of reception quality measured using the cell detection reference signal. A transmission processor transmits the measurement information. The cell detection reference signals are mapped to any one of a plurality of candidate resources, which is a part of a plurality of resources set for other reference signals in a subframe to which the cell detection reference signals are mapped.

Abstract: A repeater generates repetition signals by repeating an uplink signal over a plurality of subframes. If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format.

Abstract: A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.

Abstract: A base station (100, 300) is provided with a transmitter and a receiver. The transmitter (109) transmits a downlink signal in a downlink transmission region, in a time unit that includes the downlink transmission region, an uplink transmission region, and a gap period that is a switching point between the downlink transmission region and the uplink transmission region. The receiver (111) receives an uplink signal in the uplink transmission region, in the time unit. Furthermore, a delay tolerant signal for which a delay is tolerated more than for the downlink signal and the uplink signal is mapped to within the gap period.
