A user device receives from a base station: mixed data signals transmitted in a format whereby a plurality of data signals are transmitted using different downlink transmission power and without being mutually orthogonal; a plurality of control signals corresponding to a plurality of user devices; and information indicating an identifier for another user device. The user device determines the aggregation level for the user device itself. The user device attempts to descramble one control signal among the plurality of controls signals corresponding to aggregation levels of at least the aggregation level for the user device itself, by using the identifier and, if successful, uses the control signal and demodulates a non-orthogonal data signal. |
