摘要： There is provided a wireless communication device capable of improving a decoding performance by using an optimal selection criterion for a start address and a read direction in a circular buffer. An interlacer (13) writes an interleaved and interlaced bit sequence into a circular buffer (14). An RV decision unit (109) decides the read start address and read direction of the circular buffer (14) based on the number of non-transmitted systematic bits, the number of non-transmitted important parity bits, and/or the number of non-transmitted unimportant parity bits. A read control unit (110) controls the read start address and read end address of the circular buffer (14). A read unit (15) is controlled by the read control unit (110) to continuously read encoded bits from the circular buffer (14).

摘要： Even when a CCFI error has arisen, there is prevented occurrence of a packet error, which would otherwise be caused during the first receiving operation for reasons of erroneous storage of data into a buffer, and data are prevented from being synthesized while deviated during retransmission. A transmission Circular Buffer sequentially reads encode word data to be transmitted in reverse order from end to top like D—12, D—11, D—1. After the data have been modulated by a modulator, a multiplexer allocates modulated data symbols D—12 to D—1 to OFDM symbols from the third OFDM symbol #3 subsequent to a control channel CCH in accordance with a CCFI value (=2). After demodulating received data symbols, a receiving side rearranges the demodulated information from its end to top in reverse order from a predetermined data start point, and stores the thus-rearranged information in a receiving Circular Buffer. As a result, there is avoided receiving error, which would otherwise be caused by gap of data stored in the receiving Circular Buffer and loss of the first data.
摘要翻译：即使出现CCFI错误，也避免了由于数据错误地存入缓冲器的原因而在第一次接收操作期间引起的分组错误的发生，并且防止在重传期间数据被合成而偏离。传输循环缓冲器从D到12，D-11，D-1顺序读取从顶到顶以相反顺序发送的编码字数据。在通过调制器调制数据之后，多路复用器根据CCFI值（= 2）将控制信道CCH之后的第三OFDM符号＃3中的调制数据符号D-12至D-1分配给OFDM符号。在对接收到的数据符号进行解调之后，接收端从预定的数据起始点以相反的顺序将解调信息从其端到端重新排列，并将这样重新排列的信息存储在接收循环缓冲器中。因此，避免了接收错误，否则将由存储在接收循环缓冲器中的数据的间隙和第一数据的丢失引起。

摘要： Provided is a mobile station which can obtain an equivalent diversity effect in each communication scheme while keeping to an minimum the increase in the circuit scale of a mobile station even when the mobile station is compatible with a plurality of communication schemes. In a mobile station (100) which performs either single-carrier frequency-division multiple access (SC-FDMA) communication or orthogonal frequency division multiple access (OFDMA) communication, an interleaving unit (103) interleaves a plurality of resource elements, which are divided into a plurality of code blocks, in a plurality of code blocks when either SC-FDMA or OFDMA communication is performed. In addition, only when OFDMA communication is performed, a serial-to-parallel (SIP) converter (107) converts the data symbols to parallel streams and generates the OFDM symbols. A shifter (108) provides a different frequency shift to each OFDM symbol for the OFDM symbols input from the S/P converter (107), and distributes and places the plurality of resource elements of each plurality of code blocks after interleaving in the frequency domain.

摘要： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.
