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： A transmitter device is capable of preventing error detection of a data resource area as a result of a detection mistake of a control signal. In the device, a control unit sets, as data resource areas, only PRBs that have been imparted with numbers greater than a number that has been imparted to a PRB for which has been set a control resource area for which a downlink assignment control signal (that is, a DL grant) has been mapped. In this manner, at a terminal, if the PRB for which a downlink assignment control signal has been detected can be identified, the data resource area can be identified directly, and therefore, it is possible to prevent error detection for the data resource area as a result of a detection mistake of an uplink assignment control signal.

摘要： To improve the operation and the effect of ICIC by appropriately limiting resources of a reference signal. An SRS generating unit (154) generates an SRS as a reference signal based on SRS information transmitted from a reception unit (156), and a transmission unit (155) transmits the SRS based on the SRS information transmitted from the reception unit (156). At this time, by using information that represents an SRS drop resource as a transmission drop resource set in advance, the transmission of the SRS from the transmission unit (155) is dropped in a resource in which an SRS transmission resource used for transmitting the SRS is an SRS drop resource.
