Claim of US Patent No. 10,251,166

1. A user terminal comprising:a receiver that receives transmission mode information, indicating a transmission mode to which spatial multiplexing of a plurality of layers is applied to a downlink signal for the user terminal, via radio resource control (RRC) signaling and receives downlink control information, via a physical downlink control channel, indicating whether or not a transmission method of superposing downlink signals for a plurality of user terminals, including the user terminal, is applied in the transmission mode; and
a processor that controls reception of the downlink signal according to the transmission mode information and the downlink control information,
wherein if the spatial multiplexing of the plurality of layers is applied and the downlink signals for the plurality of user terminals are superposed, the processor controls the reception of the downlink signal based on a power ratio of the downlink signals provided from a radio base station.
