Abstract: An object is to mitigate interference by using effective knowledge or information as to an interference signal while reducing an increase in the amount of calculation. A terminal device includes a reception unit that receives downlink control information from a base station apparatus. In a case of a prescribed transmission mode, a downlink shared channel destined for the terminal apparatus is demodulated on the basis of a power offset between transmit power of the terminal apparatus and transmit power of another terminal apparatus in the downlink shared channel included in the downlink control information. Whether or not to perform interference cancellation is determined according to a value of the power offset.

Abstract: In a case that a large number of terminal apparatuses that are accommodated by contention-based radio communication technologies share a frequency resource, the number of data signals of the terminal apparatus that are non-orthogonally multiplexed in the spatial domain increases. If terminal apparatuses, of which the number exceeds the number of receive antennas or the spreading factor transmit uplink data at the same time, it is tantamount to a presence of terminal apparatuses using the same spreading code, and inter-user interference becomes a problem.
