Patent number: 8135356Abstract: 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.Type: GrantFiled: June 28, 2011Date of Patent: March 13, 2012Assignee: NTT Docomo, Inc.Inventors: Masashige Shirakabe, Takahiro Asai, Naoto Matoba, Hitoshi Yoshino
