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： To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus (eNB) transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses (UE1, UE2). Each of the reception apparatuses (UE1, UE2) detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe.

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.
