    摘要: Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.

    摘要: A multicarrier transmitting apparatus capable of improving the data symbol error rate characteristic to improve the reception quality. In this apparatus, a replacement position deciding part (141) decides, based on a number of replacements notified of by a scheduler (110), which one of a plurality of data symbols should replaced by a second pilot. Herein, a restricted condition, which is ‘RF after replacement is equal to or greater than RF before replacement minus one’, is satisfied. A replacing part (142) replaces, in accordance with the replacement position outputted from the replacement position deciding part (141), a part of the data symbols included in a repetition signal by a second pilot symbol, and outputs the resultant replaced signal to an IFFT part (105).

    摘要: A transmission apparatus capable of improving overall throughput of a system by suppressing peaks using some frequencies in a communication band. In this apparatus, modulation section (102) adaptively modulates transmission data. Combination section (103) combines the waveform of the transmission data and an inverse replica and suppresses peaks equal to or higher than a threshold. When there are peaks equal to or higher than a threshold, inverse replica generation section (112) extracts the waveform of a peak equal to or higher than the threshold and generates an inverse replica which is the waveform having the inverse characteristic of the extracted waveform. Sub-band selection section (114) selects frequencies of subcarriers for which MCS having low transmission efficiency is selected and outputs the inverse replica within the range of the selected frequency to combination section (103).

The radio communication device includes: a CCE allocation unit (104); modulation units (103-1 to 103-K); an arrangement unit (108); and a radio transmission unit (111). The CCE allocation unit (104) allocates allocation information allocated to a PDCCH which is inputted from the modulation unit (103-1 to 103-K) as follows. Among a plurality of search spaces shared by a greater number of UE groups as the CCE aggregation size of the PDCCH increases, a particular search space corresponding to the CCE aggregation size of the PDCCH and a mobile group (UE group) of the PDCCH is selected as a space to which the allocation information is to be allocated. The arrangement unit (108) arranges the allocation information in a downlink resource corresponding to the CCE of the particular search space allocated among the downlink resources secured for the PDCCH. The radio transmission unit (111) transmits an OFDM symbol having the allocation information from an antenna (112) to a mobile station.

    摘要: Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal (100) is set as a Non-CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal (100) is set as a CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit (105) generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.
