Abstract: A signal assignment unit (105) assigns a downlink control signal including resource assignment information of a PDSCH to a downlink resource. A specification unit (108) specifies a PUCCH resource using an offset value set to either a first PRB set or a second PRB set when the downlink control signal is disposed to spread over the first PRB set and the second PRB set. A signal separation unit (109) separates an ACK/NACK signal included in the specified PUCCH resource from a received signal from a terminal to which the downlink control signal has been transmitted.

Abstract: A base station that can appropriately perform feedback with regard to data transmission. A base station (100), wherein on the basis of a resource allocation configuration that was configured by a terminal (200), a DFI generation unit (106) determines a transmission method for feedback information that includes a response signal regarding uplink data. A transmission unit (110) transmits the feedback information on the basis of the transmission method.

Abstract: A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

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 with which it is possible to appropriately arrange a reference signal. In a base station (100), a control unit (101) determines a second threshold value on the basis of a first threshold value used in determining the arrangement of a reference signal. A transmission unit (105) transmits the reference signal arranged on the basis of the second threshold value.

Abstract: A terminal is disclosed, which is capable of appropriately distributing transmission power when transmission time interval (TTI) lengths are different. A transmission-power determining section (211) determines transmission power for an uplink signal in a first TTI and an uplink signal in a second TTI shorter in TTI length than the first TTI, when the second TTI uplink signal occurs during a first interval in the first TTI, so as to keep the transmission power for the first reference signal and the first TTI uplink signal constant without allocating any transmission power to the second TTI uplink signal in the first interval, and to reduce the transmission power for the first TTI uplink signal to allocate transmission power to the second TTI uplink signal in a second interval which is subsequent to the first interval in the first TTI.

Abstract: The present disclosure relates to receiving and transmitting data in a frame with subframes of a wireless communication system, each subframe being either an uplink subframe accommodating uplink signal, a downlink subframe accommodating downlink signal or a special subframe including a downlink signal portion as well as an uplink signal portion. A control signal includes a special subframe configuration specifying the length of the uplink and/or downlink portion of the special subframe. The mapping and demapping of user data and/or control data including feedback information in a transmission time interval, TTI, onto or from one subframe is then performed, wherein the length of a second TTI for mapping onto the uplink portion of a special subframe is shorter than a first TTI for mapping onto an uplink subframe, or a first number of TTIs mapped onto the uplink subframe is larger than a second number of TTIs for mapping onto the uplink portion of a special subframe. The data are received or transmitted accordingly.
