摘要： A wireless communication system in which a base station apparatus having a plurality of transmission antennas and one or more terminal apparatuses communicate with each other is provided with at least two methods of a first feedback method and a second feedback method regarding propagation path information at the time of reception. In accordance with a communication condition between the base station apparatus and the terminal apparatus, or the function of the terminal apparatus, the terminal apparatus performs feedback by one of the two methods of the first feedback method and the second feedback method. The base station apparatus performs spatial multiplexing transmission on the basis of the propagation path information that has been fed back. Thus, in a system in which CSI is fed back for MIMO transmission, desired transmission characteristics can be efficiently obtained.

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： When applying inflated lattice precoding (ILP) transmission to a multi-carrier scheme, there arises a need to notify coefficient α thereof per sub-carrier. Applying ILP transmission has proven difficult since multi-carrier schemes such as those widely adopted in mobile communication systems, etc., in recent years have an extremely large number of sub-carriers and the information volume of the control signal becomes extremely large. As such, at a transmitter device B, coefficient α is inputted to a 1/α multiplier part 15, and a DRS from a dedicated reference signal (DRS) generator part 11 is multiplied by 1/α and transmitted. At a receiver device C, an estimated signal is obtained by performing a remainder process at a reception modulo operator part 51 using a modulo width determined based on the DRS, without performing a process of a reception coefficient multiplier part with respect to a reception signal.
摘要翻译：当将充气格子预编码（ILP）传输应用于多载波方案时，需要通知每个子载波的系数α。由于近年来在移动通信系统等中广泛采用的多载波方案具有非常多的子载波，并且控制信号的信息量变得非常大，所以应用ILP传输被证明是困难的。这样，在发送装置B中，将系数α输入到1 /α乘法器部15，将来自专用基准信号（DRS）发生部11的DRS乘以1 /α并进行发送。在接收机装置C中，通过使用基于DRS确定的模数宽度，在接收模运算器部分51执行余数处理，而不对接收信号执行接收系数乘法器部分的处理，来获得估计信号。

摘要： With respect to a wireless communication system comprising a transmitter device 200, which is equipped with a function for performing inflated lattice precoding (ILP) on transmission data, and a receiver device 300, which receives a signal transmitted from the transmitter device and restores data, there is adopted a feature wherein “coefficient α” which is required when the transmitter device 200 performs the above-mentioned ILP, and which is also required when the receiver device performs data restoration, is uniquely derived using information relating to an MCS (modulation parameter) that is applied with respect to the wireless communication system (more specifically, a feature wherein a “coefficient table part,” which uniquely maps MCS information to coefficient α, is provided at both the transmitter device and the receiver device, and wherein coefficient α required at both the transmitter device and the receiver device is derived using this “coefficient table part”), thereby evading having to exchange information relating to “coefficient α” between the transmitter device and the receiver device.
