摘要： A terminal device notifies a base station device about control information associated with a receive quality of the terminal device. The base station device performs data modulation on a plurality of pieces of transmit data for the terminal device, by using a plurality of different data modulation schemes one by one, based on the control information, and spatially multiplexes the plurality of pieces of transmit data after the data modulation over a single wireless resource and transmits a spatially multiplexed signal. The terminal device receives the signal with the plurality of pieces of transmit data spatially multiplexed, and detects desirable transmit data from the receive signal, based on a first channel matrix which represents channel state information between the base station device and the terminal device and a second channel matrix in which the first channel matrix is multiplied by a transform matrix. Accordingly, an adaptive modulation technology is applied even to MIMO spatial multiplexing transmission using a LR technology, and hence a wireless communication system and so forth that can contribute to improvement in frequency utilization efficiency can be provided.

摘要： More reduction of the amount of operation than in QRM-VP is realized while maintaining transmission performance that can be achieved by VP. A precoding apparatus 109 that performs preliminary processing on transmission data transmitted from a wireless transmission apparatus including a plurality of antennas to a wireless reception apparatus includes a linear filter generation section 301 that generates a linear filter on the basis of a result of estimation of a channel between an antenna unit 111 and the wireless reception apparatus, a signal conversion section 303 that expands perturbation term candidates of a perturbation vector to be added to a transmission data vector and a reference signal associated with the transmission data in a complex plane, and a perturbation vector search section 305 that searches for the perturbation vector to be added to the transmission data vector by performing a quadrant search on the basis of the perturbation term candidates and the reference signal expanded in the complex plane. A transmission signal vector is calculated by adding a found perturbation vector to the transmission data vector and multiplying the transmission data vector by the linear filter.

摘要： A data signal component output from a reference signal demultiplexer and channel state information obtained by using DM-RS output from a channel estimating unit are input into a modulo estimating unit. In a channel compensator, a first provisional decision value sequence is calculated on the basis of the channel state information. The first provisional decision value sequence is input into a modulo calculator, and modulo calculations are performed on the first provisional decision value sequence to obtain a second provisional decision value sequence. A decision-feedback channel estimating section finds a first channel estimation value based on the first provisional decision value sequence and a second channel estimation value based on the second provisional decision value sequence. A modulo decision section decides whether or not a perturbation term has been added to a code, and uses a decision result for the selection of a demodulation method.
