Base Station Device and Channel Allocation Method
First Claim
1. A base station device that performs communication with communication terminals by implementing an adaptive process using a plurality of antennas, the base station device comprising:
- 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 allocates the empty channel selected by the channel selector to a communication terminal, in accordance with a new channel allocation request from the communication terminal.

Abstract
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.
