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: 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: Received Signal Strength Indicator (RSSI) is measured accurately even in a case where a discovery signal is transmitted. A receiver receives a plurality of subframes, at least one of which includes a discovery signal, and a measurer measures Reference Signal Reception Power (RSRP) using a first resource in which the discovery signal is mapped, measures RSSI using a second resource different from the first resource for which the discovery signal is mapped, and calculates Reference Signal Reception Quality (RSRQ) using RSRP and RSSI.

Abstract: Provided are wireless communication devices and methods. A wireless communication device can comprise: circuitry operative to map at least a first type of reference signals (RSs) onto orthogonal frequency division multiplexing (OFDM) symbol(s) other than the OFDM symbols onto which shortened transmission time intervals (TTIs) are mapped in a subframe, each of the shortened TTIs comprising 1-7 OFDM symbols; and a transmitter operative to transmit a physical channel in one of the shortened TTIs and transmit at least the first type of RSs.

Abstract: Provided are a user equipment and a wireless communication method for LAA. The user equipment comprises: a receiver operative to receive a UL grant which schedules a subframe for UL transmission; a first circuit operative to perform LBT; a transmitter operative to transmit a PUSCH in the scheduled subframe starting from one available starting position of multiple candidate starting positions in the scheduled subframe if the LBT is successful. According to present disclosure, it is possible to increase the possibility that PUSCH could be sent in the scheduled subframe after LBT.

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.
