Abstract:
1. A multicarrier mobile communication system comprising: a transmitting unit and a receiving unit which are connected with a radio network, wherein said transmitting unit comprises: a coding section configured to divide a transmission data into a plurality of code blocks, and encode each of the plurality of code blocks to generate a transmission signal; and a transmitting section configured to transmit the transmission signal, wherein said receiving unit comprises: a receiving section configured to receive the transmission signal as a reception signal, wherein when there is an error in the said reception signal, said receiving section transmits a retransmission request feedback data, which contains a NACK data indicating that there is an error in the transmission signal and a data indicating a first code block group, to the said transmitting unit, wherein first resources are assigned to each of the plurality of code blocks of the transmission signal, wherein said transmitting section assigns resources of the first code block group of a plurality of code blocks of the transmission signal to second resources which are different from the first resources, based on the retransmission request feedback data, and retransmits the transmission signal to said receiving unit, wherein said receiving unit further comprises: a decoding section configured to perform iterative decoding of an error correction decoding and error detection to each of a plurality of code blocks of the reception signal, wherein said decoding section terminates the iterative decoding to a first code block group, in which an error has not been detected before a first setting number of times of iteration, among the plurality of code blocks of the reception signal, wherein said transmitting section assigns resources of the first code block group of a plurality of code blocks of the transmission signal to second resources which are fewer than for the first resources, wherein said receiving unit further comprises: an iteration count recording section configured to record decoding iteration counts as the numbers of times of iterative decoding to the plurality of code blocks of the reception signal, respectively, wherein the retransmission request feedback data further includes a data indicating the decoding iteration counts, wherein the decoding iteration counts data includes a data indicating the first code block group, and wherein said transmitting section: compares each of the decoding iteration counts indicated by the decoding iteration counts data with the first setting count to select a first decoding iteration count group which is fewer than the first setting iteration count from the plurality of decoding iteration counts, assigns the resources of the first code block group corresponding to the first decoding iteration count group among the plurality of code blocks of the transmission signal from the first resources to the second resources, and retransmits the transmission signal to said receiving unit.
