Patent ID: 8654710

Claim:
A terminal apparatus that can demodulate signals transmitted by multiuser multiple-input multiple-output, the terminal apparatus comprising: a channel estimating section; a reception weight creating section; and a control information extracting section, wherein: when a common control signal is received, the reception weight creating section obtains the common control signal using reception weight based on a channel matrix estimated by the channel estimating section, and the control information extracting section extracts resource assignment information and precoding information contained in the common control signal; when spatially multiplexed signals are received, the reception weight creating section obtains dedicated data and a dedicated control signal using the reception weight based on the precoding information, and the control information extracting section extracts dedicated identifier information and modulation and coding scheme information contained in the dedicated control signal; the common control signal contains information indicating the number of spatial multiplexing of transmitted signals; and whether or not to demodulate spatial multiplexing signals is controlled by comparing between the number of spatial multiplexing and interference cancellation capability of the terminal apparatus.
