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： There are disclosed a radio communication device and others capable of generating in a short time a secret key common to a base station and a mobile station in a radio communication system using the MIMO technique and starting the encrypted communication at an early stage. In this device, in ST545, when a channel coincidence judgment unit (105) and a channel coincidence judgment processing unit (205) respectively judge that the channel matrix generated by the base station completely coincides with the channel matrix generated by the mobile station or they do not coincide completely but they can coincide finally by error correction of the secret key or the like, according to the judgment result indicated in the channel coincidence judgment signal generated in ST540-2, ST545 is followed by ST550. On the other hand, when the channel matrix generated by the base station does not coincide completely with the channel matrix generated by the mobile station and they do not coincide finally even after error correction of the secret key, ST510 is again executed after ST545.

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.
