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: Disclosed is a terminal that performs an appropriate transmission power control for both signals intended for a base station and for D2D communication. The terminal includes: a reception processing section that receives a control signal including a TPC command selected from among a plurality of candidate values; and a transmission power control section that controls a first transmission power for an uplink data signal for a base station, using a first correction value corresponding to the received TPC command, and that controls a second transmission power for a signal for D2D communication using the first correction value or a second correction value corresponding to the received TPC command. In the terminal, the first and the second correction values are set for each candidate value of the TPC command; and the second correction value is set lower than the first correction value for at least one of the candidate values.

Abstract: The present disclosure provides wireless communication methods for repeated transmission of channels, and wireless communication devices therefor. In one embodiment, the gap between the starting subframe of a first channel and the starting subframe of a second channel is defined or configured. In another embodiment, Mx*W=M and Mx*n=N is satisfied, where Mx is the number of subframes reserved for the channel in one HARQ process, M is RTT for one HARQ process, W is a positive integer and represents the maximum number of HARQ processes transmitting the channel within M subframes, N is the gap between the starting subframes of the channel in two HARQ processes, and n is a positive integer. In yet another embodiment, time-frequency resources for the channel in different HARQ processes are different.

Abstract: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit (101) in base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit (103) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.
