TRANSMISSION DEVICE, RECEPTION DEVICE, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A transmission device capable of flexibly setting the transmission mode, even in cases when the candidates for the resource domain to be used to transmit a control signal to a terminal include both a first downlink resource domain that can be used as either a control channel or a data channel and a second downlink resource domain that can be used as a control channel, wherein a transmission mode setting unit (101) sets one transmission mode for each of the first and second downlink resource domains, said transmission mode being selected from among a plurality of transmission modes in which a plurality of control signal formats and the transmission methods that correspond to the control signal formats and are used to transmit data to a terminal (200) have been associated.
