PURPOSE:To cope with the state from high to low traffic by varying the range of search in response to the state of traffic. CONSTITUTION:A traffic monitor section 18 receives all reception signal received by an antenna section 20 via a reception section 12, checks the traffic state on a channel based on the reception signal to generate a control parameter. The parameter is a value being a division of the number of collision slots during an object period by the number of operating slots during the object period, for example. Based on the parameter, the search section 15 adjusts the number of slots in a storage section 153. Thus, the state of traffic from low to high traffic is coped with flexibly. |
