摘要： A macro-cell base station (MeNB) transmits, via a PDCCH in a first subframe, both allocation information indicating a radio resource allocated to a radio terminal (MUE) and subframe information indicating a second subframe which is later than the first subframe and in which an allocation is applied in accordance with the allocation information. The radio terminal (MUE) receives the allocation information and the subframe information from the macro-cell base station (MeNB) via the PDCCH in the first subframe. The macro-cell base station (MeNB) omits the transmission of the allocation information in the second subframe, while the reception unit on the terminal side omits the reception of the allocation information in the second subframe.

摘要： A radio communication device according to the present invention adaptively controls directivity of a transmission radio signal by using a plurality of element antennas on the basis of a received radio signal received from a communication target counterpart radio communication device. The radio communication device includes a transmission controller configured to process the transmission radio signal according to a first control method for adaptively controlling the directivity, a propagation path state detector configured to detect fluctuation state of a propagation path to a counterpart radio communication device, and a judgment unit configured to judge whether or not to change the directivity on the basis of the fluctuation state of the propagation path. If it is judged that the directivity is to be changed, the transmission controller switches to a second control method that is different from the first control method, and processes the transmission radio signal according to the second control method.

摘要： A radio base station includes: a propagation path characteristic acquisition unit which acquires propagation path characteristics between a radio communication terminal and a radio base station; and a channel controller which reports to the radio communication terminal that channel allocation information is transmitted by using a dedicated control channel if the acquired propagation characteristic satisfies a predetermined condition. After the channel control unit has reported to the radio communication terminal that the channel allocation information is transmitted by using an dedicated control channel, the channel control unit and a MAP processing unit transmit the channel allocation information by using an dedicated control channel instead of a broadcast control channel in the downstream frame.
