The present invention improves transmission efficiency in unlicensed bands. This base station comprises: a control circuit for determining a cyclic prefix (CP) length coordinated between a terminal and the base station; and a transmission circuit for transmitting control information regarding the determined CP length to the terminal.

Base station, terminal, and communication method

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.

This terminal comprises a reception circuit that receives parameters pertaining to a license-exempt band, and a control circuit that determines information included in uplink control information on the basis of the parameters.

Terminal and communication method

This base station is provided with: a control circuit which determines a disposition method for a downlink control channel signal in at least one among a first period before a timing based on a carrier sense and a second period after the timing based on the carrier sense on the basis of information about at least one among the number of times a downlink control channel signal is blind-decoded and the number of resources for channel estimation; and a transmission circuit which transmits the downlink control channel signal on the basis of the determined disposition method.

Base station, terminal, transmission method, and reception method

Provided is a terminal capable of improving utilization efficiency of an uplink resource in an unlicensed band. In a terminal (), a transmission control unit () 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 () transmits the uplink data on the basis of the second end position.

Terminal, base station, transmitting method, and receiving method

According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (), a repetition control unit () determines a data repetition pattern for a terminal (). A transmission unit () repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal () by dynamic signaling.

Transmission device, reception device, transmission method, and reception method

A wireless station that belongs to a communication cell includes a receiver which, in operation, receives a trigger frame transmitted from an access point that belongs to an interference cell and a controller which, in operation, determines, based on at least one parameter included in the trigger frame and reception power value of the trigger frame received at the wireless station, whether the wireless station is allowed to transmit to other wireless station that belongs to the communication cell, wherein the at least one parameter includes a value set based on transmit power value of the trigger frame transmitted from the access point.

Provided is a terminal which can suitably apply precoding to a PDCCH. In the terminal (), when a first CC is notified of scheduling information for each of a first component carrier (CC) and a second CC, a restriction determination unit () determines, on the basis of a subcarrier interval of the CC to be scheduled by means of the scheduling information among the first CC and the second CC, the maximum number of blind decodings when the scheduling information is blind-decoded. An extraction unit () performs the blind decoding on the basis of the maximum number of blind decodings and extracts the scheduling information.

Terminal and communication method for blind-decoding scheduling information

A terminal apparatus includes a receiver and a transmitter. The receiver receives, from a base station, a downlink assignment index (DAI) that is transmitted by means of a downlink control information (DCI) format. The DAI indicates an accumulative number of a transmitted physical downlink shared channel (PDSCH) included in a group of PDSCHs. A range of the accumulative number of which the DAI is indicative is variably configured. The transmitter, in operation, transmits, to the base station, hybrid automatic repeat request acknowledgement (HARQ-ACK) information based on the DAI.
