Abstract

The present invention is designed to reduce the deterioration of communication quality and so on even when communication is performed by applying different configurations than in existing LTE systems. A receiving section that receives a downlink control channel, and a control section that 5 controls receipt of the down link control channel, are provided, the downlink control channel is transmitted using downlink control channel elements including a plurality of resource element groups (REGs), and the control section controls receiving processes per REG group comprised of a plurality of REGs. 10 Fig. 3
