    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.

    摘要: When signals received by receiving antennas included in each terminal are subjected to MMSE combining, it is configured that each terminal is able to grasp position of desired signal in signal vector obtained after combining. A base station 100 receives by a receiving antenna 23 from the terminal apparatus channel state information between a transmitting antenna 16 and spatial multiplexing object antennas included in each terminal apparatus. A transmit weight calculation unit 19 calculates a transmit weight for performing spatial multiplexing transmission to the terminal apparatus based on the channel state information. Transmit weight multiplication unit s 12 and 18 multiplies an information signal addressed to each terminal apparatus to be performed spatial multiplexing by the transmit weight. A signal multiplexing unit 13 multiplexes the information signal multiplied by the transmit weight and an information to specify the information signal that needs to be demodulated by each terminal apparatus.

    摘要: Reception quality measurement results of respective channels which have been outputted from a reception quality measuring section 308 are inputted to a selected channel determining section 341 and a channel quality information generating section 342. Moreover, the number of selected channels M which has been previously defined or the number of selected channels M which has been outputted from a control information obtaining section 314 is inputted to the selected channel determining section 341 and a channel identification information generating section 343. The selected channel determining section 341 selects M channels in order of goodness of the reception quality measurement result, as the selected channels, based on the reception quality measurement results of the respective channels, and outputs a selection result. The channel quality information generating section 342 generates and outputs channel quality information representing the reception quality measurement results related to the selected M channels, based on the selection result outputted from the selected channel determining section 341. The channel identification information generating section 343 selects one of a first representation format for representation with M identification numbers (channel numbers) indicating the respective selected channels, and a second representation format for representation with a bit sequence representing whether or not each of all the channels is included in the selected channels, in a binary manner, based on the number of selected channels M, and uses the selected representation format to generate and output channel identification information based on the selection result outputted from the selected channel determining section 341. A multiplexing section 344 combines the channel quality information outputted from the channel quality information generating section 342 and the channel identification information outputted from the channel identification information generating section 343 to generate and output notification information.
