Abstract: A directivity control section 103 performs weight control over a received signal using channel estimation and optimum weights, performs processing such as generation of the received signal and generates a plurality of weight-controlled transmission signals. A received signal demodulation section 104 extracts an SIR measurement result from the received signal. A scheduler section 105 decides which terminal should be assigned to a channel to be adaptively modulated from the SIR measurement result and at the same time decides the modulation multi-valued number and coding rate of the signal to the terminal. A transmission signal generation section 106 modulates a transmission signal such as a reference signal or packet data. A directivity switching instruction section 107 controls switching between directivities so as to maintain the same directivity after the reference signal is transmitted with a directivity until packet data is transmitted with a directivity. This makes it possible to receive packet data with high quality, improve efficiency of a radio frequency band and maximize communication path utilization efficiency.

Abstract: A duplicating section duplicates a bit sequence to be input, and a 16QAM section modulates a bit sequence of a duplicating source to form a symbol, a 16QAM section modulates the duplicated bit sequence to form a symbol, an S/P section parallel converts the symbol sequence input in series, an S/P section parallel converts the symbol sequence input in series, and an IFFT section 15 provides IFFT processing to the input symbol sequence. Since each of multiple same bits duplicated by the duplicating section is included in a different symbol, each of the multiple same bits is allocated to each of multiple subcarriers each having a different frequency by IFFT processing. As a result, a multicarrier signal including the multiple same bits each having a different frequency is generated.

Abstract: A wireless communication base station apparatus that can raise the usage efficiency of the frequency resources of the whole system in a multicarrier transmission. In this apparatus, a separating part (103) separates symbols received from a modulating part (102) into symbols to be assigned to a first subcarriers group and into symbols to be assigned to a second subcarriers group. A setting part (106-1) sets the transmission power of the symbols, which are to be assigned to the first subcarriers group, to a power value as calculated by a power calculating part (105), while a setting part (106-2) sets the transmission power of the symbols, which are to be assigned to the second subcarriers group, to a power value as calculated by the power calculating part (105). Thus, the transmission power control is differently performed between the symbols to be assigned to the first subcarriers group and the symbols to be assigned to the second subcarriers group.

Abstract: 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.

Abstract: A transmitting apparatus and a transmitting method wherein the systematic bit reception quality can be improved and the throughput performance can be improved. An IR parameter control part (101) controls, based on the number of retransmissions, the ratio of systematic bits to parity bits in mapping them to packets, and controls to map a parity bit to an initially transmitted packet, while mapping a systematic bit to a retransmitted packet. An encoding part (102) generates the systematic bits and parity bits and maps them to the packets in accordance with the IR parameters. A transmission power calculating part (105) calculates, based on reception quality information of the initially transmitted packet fed back from a receiving end, the transmission power of the transmitted packet to which the systematic bit is mapped. A transmission power control part (106) controls the transmission power of the retransmitted packet such that it is equal to the transmission power as calculated by the transmission power calculating part (105).

Abstract: A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S) of spatial multiplexed symbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.
