摘要： Disclosed is a radio transmission device capable of improving a transmission stream error resistance and preventing lowering of a throughput of a communication system. In this device, according to the feedback information from the radio reception device, a repetition control unit (110) decides ranking of each stream, sets a higher repletion rate for a higher stream. This is instructed to repetition units (103-1 to 103-N). According to the repletion rate decided by a repletion control unit (110), the repletion units (103-1 to 103-N) subjects the stream outputted from modulation units (102-1 to 102-N) to a repetition process, and outputs it to transmission RF units (104-1 to 104-N).

摘要： A wireless communication apparatus wherein the power consumption can be reduced. In this apparatus, a code block dividing part (101) divides a transport block, in which filler bits have been inserted, into a plurality of code blocks. A mapping control part (107) controls, based on both scheduling information, which is received from a scheduler (not shown) and indicative of physical channel resources to be used for code block transmission, and the number of filler bits which is received from the code block dividing part (101), the plurality of code blocks so that they will be mapped to the respective physical channel resources in such an order that a respective code block having a less number of filler bits will be mapped to a respective more forward physical channel resource. A mapping part (108) then maps, based on mapping information received from the mapping control part (107), data symbols, which are received from the modulating parts (106) of the respective ones of code block processing parts (102-1 to 102-C), to the physical channel resources.

摘要： Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.
