Abstract: In a terminal, a transmission power control unit controls the transmission power of an uplink channel (the PUSCH) by using transmission power control information (a TPC command) indicating one from among a plurality of candidate values. A wireless transmission unit transmits the uplink channel with the above transmission power. Instruction information for resetting a control value (closed loop correction value) to be used in a closed loop control of the transmission power is associated with at least one value among the above plurality of candidate values.

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: 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: In a terminal, a transmission power calculation unit calculates a transmission power of an uplink signal by using transmission power control information indicating one value from among a plurality of candidate values respectively associated with correction values that correct a control value to use in a closed loop control of the transmission power. A wireless transmission unit transmits the uplink signal with the above transmission power. A first correction value and a second correction value having a larger step size than the first correction value are associated with each of the plurality of candidate values.

Abstract: In a transmitter, an assignment circuit maps a phase tracking reference signal (PT-RS) onto a subcarrier, and a transmitting circuit transmits a signal containing the phase tracking reference signal. The phase tracking reference signal is mapped onto a different subcarrier for each cell, group, or mobile station.
