Abstract: Provided is a relay transmission method capable of obtaining the diversity effect even when a relay station has detected an error in a relay signal when performing communication between a base station and a mobile station via a relay station. In the relay station used in this method, a decoding unit (104) performs error-correction-decoding of a systematic bit by performing repeated decoding such as a turbo decoding by using a parity bit and obtains a decoding result formed by a systematic bit after the error-correction-decoding. An error judging unit (105) judges whether the decoded result has an error by using CRC (Cyclic Redundancy Check). An encoding unit (106) performs error-correction-encoding of the decoded result and obtains a systematic bit after error-corrected-encoded and a parity bit. A selection unit (107) selects the decoded result inputted from the decoding unit (104) or the bit string inputted from the encoding unit (106) according to the judgment result obtained by the error judging unit (105) and outputs it to a modulation unit (108).

Abstract: A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station (200) incorporating this wireless receiving apparatus, a selecting part (205) selects a plurality of the same symbols in accordance with a mapping pattern established at the time of generating OFDM symbols in a base station. A correlation value calculating part (207) determines correlation values between the subcarriers of the same symbols to generate an R-matrix, and further determines an inverse matrix of the R-matrix. An MMSE processing part (208) performs an MMSE processing to determine a weight (W) from both a P-vector received from a channel estimating part (206) and the inverse matrix of the R-matrix received from the correlation value calculating part (207). Multipliers (209-1 to 209-N) multiply each of the symbols selected by the selecting part (205) by the weight determined by the MMSE processing part (208). A combining part (210) combines the symbols as multiplied by the weight.

Abstract: A spread code to be allocated to transmission data is changed at a previous transmitting time and a next transmission time. For example, at transmission of the first packet (first transmission), symbols “1” to “4” are spread by spread code #0, while at transmission of the second packet (retransmission), symbols “1” to “4 ” are spread by spread code #1. As a result, since despread signals of the respective symbols obtained by a plurality of reception times on a receiver side are synthesized, it is possible to eliminate a reception symbol having an extremely small reception level, so that reception quality can be improved.

Abstract translation: 要分配给发送数据的扩展码在先前的发送时间和下一个发送时间被改变。 例如，在发送第一分组（第一发送）时，符号“1”〜“4”由扩展码＃0扩展，而在发送第二分组（重发）时，符号“1”〜“4” 由扩展码＃1扩展。 结果，由于合成了通过接收机侧的多个接收时间获得的各个符号的解扩信号，所以可以消除具有极小接收电平的接收符号，从而可以提高接收质量。

Abstract: There are disclosed a random access method for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. In this device, in step ST320, a RACH sub-channel allocation unit (211) allocates a transmission packet inputted from a replication unit (202) to an arbitrary sub-carrier at the RACH arbitrary time slot at random. In step ST330, an allocation unit (210) judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit (211). When the allocation unit (210) judges that an overlap is generated in the allocation result, the allocation unit (210) causes one of the RACH sub-channel allocation units (211) which has caused the overlap to again perform allocation of step ST320. On the other hand, when judgment is made that no overlap is generated in the allocation result, step ST340 is executed.
