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： 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： Provided is a radio communication device which can obtain an error ratio characteristic equivalent to the one obtained by using a tail bit, without using a tail bit in the error correction and encoding. The device includes: a blocking unit (106) which adds a bit indicating an error detection result in a CRC unit (105) to control data (a bit string) so as to constitute an encoded block and outputs the encoded block to an encoding unit (107); and the encoding unit (107) which corrects and encodes the encoded block. The blocking unit (106) forms an encoded block by a bit string of control data and a probability deviation existence bit added to the tail of the bit string.

摘要： A wireless communication apparatus and an error detection result feedback method wherein unnecessary retransmissions are avoided to improve the system throughput. At a base station (200), a decoding unit (205) decodes code words, which have been mapped to a TTI bundle, for the respective TTIs in the TTI bundle. An error detecting unit (206) detects errors in the decoding results. A control information generating unit (209) sequentially transmits, in accordance with detection timings, error detection result information related to the code word transmitted in the tail TTI in the TTI bundle, as well as error detection result information related to the code word transmitted in at least one of the other TTIs. In this way, an apparatus that transmits the code words can use the result of error detection in the tail TTI as a reference used for deciding the execution of a retransmission, so that unnecessary retransmissions can be avoided.

摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.
