Abstract: A radio transmission apparatus performs communications with high transmission efficiency. In this apparatus, a modulator modulates data and outputs to a first spreader. A second modulator modulates data under a modulation scheme having a higher M-ary number than the first modulator and outputs the modulated data to a second spreader. The first spreader spreads the data and outputs the spread data to a frequency domain mapping section. The second spreader spreads the data and outputs the spread data to a time domain mapping section.

Abstract: Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.

Abstract: A base station apparatus that limits the influx of speech data into a packet channel and that enables the service quality of the packet channel to be prevented from degrading. In this apparatus, a protocol detecting section (301) detects a protocol contained in an IP header of a packet. Based on the protocol, a packet type detecting section (302) detects a type of packet. Based on the type of packet, a delay addition control section (303) determines whether or not to add a delay. Specifically, when the packet is of VoIP, the delay addition control section (303) instructs a switching section (304) to output the packet to a delay adding section (103), and further instructs the delay adding section (103) to add a delay. Meanwhile, when the packet is an IP packet, the delay addition control section (303) instructs the switching section (304) to output the packet to a scheduler (104).

According to this apparatus, a mobile station (10) generates a transport signal addressed to a base station (30) and transmits it to a plurality of relay stations (20-1,20-2), each of which then generates a relay signal from the transport signal and transmits the relay signal to the base station (30).

An SD number determination unit (152) determines an SD number based on the channel quality information of a mobile station and a threshold value that is set by a threshold value setting unit (151). A transmission bandwidth determination unit (153) determines the transmission bandwidth necessary for transmission of the transmission data.

Abstract: Disclosed is a wireless communication device that, when both localized transmission and distributed transmission are used, can obtain channel estimation accuracy equivalent to that of localized transmission with distributed transmission. With this device, a setting unit (108) sets the power density of a reference signal by setting the arrangement density in the time domain of the reference signal according to the continuity in the frequency domain of the reference signal. In addition, the setting unit (108) increases the arrangement density in the time domain of the reference signal as the continuity decreases. A transmission RF unit (111) transmits a reference signal having the power density that has been set by the setting unit (108).
