Abstract: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a control unit (211) determines a processing format for a response signal or for an uplink control channel used for transmission of the response signal, in accordance with request conditions for a response signal of downlink data. A transmission unit (216) uses the uplink control channel to transmit the response signal on the basis of the determined processing format.

Abstract: The present invention provides a transmitter which can suitably perform a transmission power control in a PT-RS port. In this transmitter (100), a control unit (101) determines a transmission power for transmitting a reference signal (PT-RS) for phase tracking and a data signal within a range in which the maximum transmission power for each antenna port is not exceeded. In addition, a transmission unit (105) transmits the reference signal for phase tracking and the data signal at the transmission power determined by the control unit (101).

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.
