Abstract
A network control system for controlling a plurality of nodes respectively corresponding to, and provided in, a plurality of radio zones. Each node has a corresponding base station, where a mobil station travels among the plurality of radio zones and communicates with the base station of a respective node when travelling in a radio zone corresponding to the respective node. Each base station transmits a transmission signal for the corresponding node to adjacent nodes, receives transmission signals transmitted from the base stations of adjacent nodes and spatially filters the received transmission signals. Each base station includes (a) a notification unit notifying the base stations of adjacent nodes of transmission timing information of the transmission signal of its own node, and (b) a correction unit receiving transmission timing information from the base stations of adjacent nodes indicating the timing of the transmission signals of the adjacent nodes, and correcting the timing of the transmission signal of its own node to minimize a difference between the timing of the transmission signal of its own node and the timing of the spatially filtered transmission signals received fr…
