Claim:
A base station apparatus, comprising: a distribution unit configured to distribute control information on a per-segmented area basis, the segmented area resulting from segmentation of a coverage area into multiple segmented areas; a storage unit configured to store the control information corresponding to the segmented areas; a determination unit configured to determine as a distribution method for the segmented areas one of a first distribution method of periodically distributing the control information corresponding to the segmented areas in the coverage area and a second distribution method of distributing the control information corresponding to one of the segmented areas requested by a terminal apparatus in response to a request by the terminal apparatus; and a counting unit configured to count a number of requests for the control information from the terminal apparatus in response to a control information request signal received when the control information corresponding to said segmented area is requested by the terminal apparatus, wherein the determination unit determines whether to distribute the control information in accordance with the first distribution method of periodically distributing the control information based on the number of requests, and if the control information request signal received when the control information corresponding to said segmented area is requested by the terminal apparatus is not received, the determination unit determines to distribute the control information in accordance with the first distribution method of periodically distributing the control information, and the counting unit applies a weight coefficient corresponding to the number of requests.
