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 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.

Abstract: For the purpose of reducing the deterioration of the quality of communication and/or the drop in the efficiency of the use of resources even when communication is carried out based on different configurations from those of existing LTE systems, according to one aspect of the present invention, a user terminal has a receiving section that receives a downlink control channel, which is transmitted by using a downlink control channel element comprised of a plurality of resource element groups (REGs) and/or one or more REG groups, and a reference signal, which is used to demodulate the downlink control channel, and a control section that controls receipt of the downlink control channel in a certain field, and an allocation pattern of the reference signal is configured in association with at least one of the REG group, the downlink control channel element and the certain field.
