摘要： A radio receiver apparatus and a radio transmitter apparatus wherein the energy loss caused by addition of GI is suppressed, while the reception quality is improved. A signal having been subjected to an IFFT process is repetitively transmitted N times with a length of one OFDM symbol interval. At a receiver apparatus receiving the transmitted signals, a leading data extracting part (207) extracts, from the leading data portions of the direct waves of the received signals, portions that are not interfered with by temporally adjacent data. A combing part (209) combines the received signals in such a manner that align the rear end of each repetitively transmitted data portion except the leading data portion with the rear end of the leading data portion extracted by the leading data extracting part (207). The combined signal is then subjected to an FFT process in an FFT part (210).

摘要： A wireless communication apparatus enabling improved system throughput while limiting the amount of signaling for feedback information. In this apparatus, a setting unit (101) sets transmission power differently for each of a plurality of sub-packets obtained by dividing transmission data (transmission packet). Here, the setting unit (101) sets transmission power differently for each of the plurality of sub-packets so that the total transmission power for the plurality of sub-packets becomes the same as the transmission power that is allocated in advance to the transmission packet that constitutes the plurality of sub-packets. A dividing unit (102) divides the transmission data (transmission packet) into a plurality of sub-packets. Then, a transmitting wireless communication apparatus (100) transmits the plurality of sub-packets in order of sub-packets of higher transmission power (lower error rate).

摘要： It is possible to provide a radio communication relay device, a radio communication base station device, a radio communication system, and a radio communication method which can effectively use resources and suppress a data delay and system complexity. When a terminal starts an upstream communication with a base station via a repeater in ST403, the base station simultaneously allocates to the terminal, a resource for an initial transmission and a resource for a retransmission by using Grant 1. If the repeater successfully receives UL data transmitted from the terminal in ST404, the repeater relays, in ST406, the UL data transmitted from the terminal, to the base station by using the resource for retransmission which has been allocated to the terminal.

摘要： An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.
