摘要： Upon receipt of a new channel allocation request from a mobile communication terminal, a suitable channel is allocated. A base station device performs communication with communication terminals by implementing an adaptive process using a plurality of antennas, and includes an interference recognizing unit that recognizes a level of interference on empty channels for use in the communication, a channel selector that selects an empty channel to be allocated based on a result recognized by the interference recognizing unit, and a channel allocator that, when there is a new channel allocation request from a communication terminal, allocates the empty channel selected by the channel selector to that communication terminal.

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.
