Abstract: A DCI receiving unit receives downlink control information (DCI) indicative of allocation of an uplink (UL) signal of a first TTI (long TTI) or an uplink signal of a second TTI (sTTI) having a shorter TTI length than the first TTI; a transmission power determination unit determines transmission power of the uplink signal of the first TTI and transmission power of the uplink signal of the second TTI; and a transmitting unit transmits the uplink signal of the first TTI and the uplink signal of the second TTI by using the determined transmission power on the basis of the downlink control information. The transmission power determination unit reserves desired transmission power for the uplink signal of the second TTI in the first TTI in a case where decoding of the downlink control information indicative of allocation of the uplink signal of the second TTI to be transmitted within the first TTI (e.g., a subframe) is completed before start of transmission of the uplink signal of the first TTI.

Abstract: Provided is a terminal capable of appropriately disposing a reference signal. In the terminal (200), a reception unit (201) receives a downlink signal, a DCI reception unit (203) monitors, in the downlink signal, a candidate position of a control channel, and detects control information addressed to the terminal. The number of times the candidate position of a first control channel is monitored is less than the number of times the candidate position of a second control channel is monitored.

Abstract: UEs each monitor a search space in multiple CORSETs and appropriately detect a DCI. In a base station (100), a DCI generator (102) selects one of multiple cases each indicating a combination of CORSETs to be monitored by a terminal (200) among multiple control channel regions (CORSETs). A transmitter (106) indicates, by higher-layer signaling, configuration information indicating the multiple cases, and indicates the selected case by dynamic signaling.

Abstract: In a base station, a setting unit for setting the number of detections sets at least one search space that includes plural control channel candidates to be targets of detection of a control signal in a terminal, and a transmission unit transmits the control signal that is mapped on any of the plural control channel candidates in the search space. Here, the number of detections in the search space by the terminal is determined based on settings of the terminal.

Abstract: A base station is disclosed that enables an efficient use of resources even when a TTI length is shortened. In this base station, a PDCCH section (103) generates one piece of downlink control information (DCI) containing control information for a plurality of first transmission time intervals (TTIs) each having a TTI length shorter than a second TTI, and a transmission section (107) transmits the DCI. Control information on retransmission processing for a data signal is configured for each of the plurality of first TTIs while control information other than the control information on the retransmission processing is configured in common among the plurality of first TTIs in the DCI.

Abstract: A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.

Abstract: A repetition unit (212) performs a repetition for mapping a data signal and a demodulation reference signal (DMRS) repeatedly at a symbol level over a plurality of subframes. A signal allocation unit (213) maps, in the a plurality of subframes, the repeated DMRS to symbols other than symbols corresponding to an SRS resource candidate, which is a candidate for a resource to which a sounding reference signal (SRS) to be used to measure an uplink received signal quality is to be mapped. A transmission unit (216) transmits an uplink signal (PUSCH) including the DMRS and the data signal over the a plurality of subframes.

Abstract: In a terminal, an SRS drop control unit drops a portion of partial bands from among a plurality of partial bands in a case where transmission power for reference signals generated using a plurality of sequences having a sequence length that corresponds to a partial band exceeds a threshold value. Furthermore, a radio transmission unit transmits the reference signals by means of the remaining partial bands other than the portion of partial bands that are dropped from among the plurality of partial bands.
