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: In a terminal (200), a Pre-IFFT unit (204) generates a signal waveform for multicarrier transmission (OFDM) or single carrier transmission (DFT-s-OFDM) in uplink. A transmitter (208) transmits a signal with the generated signal waveform using a resource block (PRB) allocated to the terminal (200). In this process, a restriction is imposed on the number of resource blocks for which the Pre-IFFT unit (204) is allowed to generate the signal waveform for the single carrier transmission. Thus, it is possible to efficiently switch between OFDM and DFT-s-OFDM in the signal waveform generation.

Abstract: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.

Abstract: Repetitions of a control signal across a plurality of first subframes and a data signal allocated to a resource indicated by the control signal are received. Repetition of a response signal for the data signal across a plurality of second subframes is performed, and a transmission signal is generated by multiplying the response signals in the second subframes by, among a plurality of first sequences orthogonal to one another, components of one of the first sequences which is associated with the first subframes, respectively.

Abstract: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.
Abstract translation: 如果对下行链路数据信号和上行链路信号的响应信号进行重复发送，则使用从上行链路信号的重复发送开始的第一子帧开始的一定数量的连续子帧重复发送上行链路信号， 使用至少一定数量的连续子帧，以响应信号的重复发送开始的第二子帧开始重复发送响应信号。 第一子帧被设置为与第二子帧相同。
