摘要： To provide a radio communication control apparatus and a radio communication control method capable of controlling simultaneous transmission and reception so as not to degrade system throughput.A simultaneous transmission and reception controller 106 determines whether the simultaneous transmission and reception using the same frequency are possible, based on radio spectrum environment information of an opposite party of communication and radio spectrum environment information of a self-apparatus. When the simultaneous transmission and reception using the same frequency are determined to be possible, a control signal transmission section 109 transmits instruction information, indicating that the simultaneous transmission and reception are possible, and a transmission parameter thereof, to the above communication terminal. After the transmission parameter is set, a communication section 111 executes simultaneous transmission and reception with the above communication terminal using the same frequency, when the simultaneous transmission and reception using the same frequency are determined to be possible.

摘要： In the communication system, a transmission signal based on the first radio access scheme is generated, and in the communication system a transmission signal based on the second radio access scheme different from the first radio access scheme is generated. A usage status of the frequency spectrum of the transmission signal based on the first radio access scheme, as well as the known parameters of the transmission signal based on the second radio access scheme, are determined by the pulse-shaping controller. Then, the pulse-shaping controller performs control so as to pulse-shape the transmission signal based on the first radio access scheme by means of the transmit filter on the basis of the result of the above determination, or performs control so as to pulse-shape the transmission signal based on the second radio access scheme by means of the transmit filter on the basis of the result of the above determination.
