    摘要: A wireless communication apparatus that allows channel information to be reproduced with high precision at a transmitting end without increasing feedback information amount. In this apparatus, a channel estimating part (103) uses received pilot signals to perform channel estimation for each channel. A correlation detecting part (104) uses the result of the channel estimation to obtain correlation values between the channels, thereby detecting correlation values of all channels. An amplitude/phase ratio determining part (105) determines, based on the correlation values, the quantization bit ratio of the amplitude and phase of channel information to be used when those amplitude and phase are quantized. A feedback information generating part (106) quantizes the channel information in accordance with the determined ratio of the amplitude and phase.

    摘要: A transmitter, a receiver and a communication method enabling improvement of the data rate of an MIMO system. One signal x2 out of the three signals is combined with the other two signals x1, x3 respectively to generate two combined signals x1+x2, x2+x3. The combined signals are transmitted through transmission antennas (102, 103). A signal separating section (106) of the receiver separates the received signals r1, r2 into two signals y1, y2 by a signal separation processing such as the ZF. An MLD processing section (107) generates MLD evaluation formulae using y1, y2 and performs an MLD processing in which x2 is cancelled from y1, y2 and evaluation formulae about x1, x3 are generated, and a maximum likelihood estimation is performed. As a result of the MLD processing, x1, x3 are detected. In a canceling section (108) the detected x1, x3 are canceled from y1, y2, and x2 is detected.

    摘要: A radio transmitting apparatus, a radio receiving apparatus, a wireless communication method and a wireless communication system wherein even when a channel correlation is large, the channel capacity and the feedback amount can be improved. In ST401, a receiving apparatus (200) determines that the channel correlation value exceeds a predetermined threshold value. In ST402, a transmitting apparatus (100) is instructed to perform 42 MIMO transmission. In ST403, the transmitting apparatus (100) determines a pair of antennas exhibiting the highest channel correlation. In ST406, the receiving apparatus (200) uses, based on the pair information, a channel matrix, which comprises channel estimation values, to calculate a delay shift amount. In ST407, the delay shift amount is fed back to the transmitting apparatus (100). In ST408, the transmitting apparatus (100) uses the pair information and delay shift amount to combine SDM and a cyclic sample delay diversity, thereby transmitting data.

    摘要: It is possible to provide a radio communication terminal device, a radio communication base station device, and a CQI feedback method which can improve the CQI reproducibility while reducing the feedback overhead. A terminal channel judgment unit judges whether a local terminal is a TU terminal or a LOS terminal. A feedback CQI decision unit selects a Best-M report if the local terminal is the TU terminal, and selects a DCT report if the local terminal is the LOS terminal. The feedback CQI decision unit feeds back the CQI by using the selected report method.

    摘要: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3
