Abstract
A method of reusing frequency bands between base stations of a terrestrial mobile communications network and a satellite communications network, comprising allocating the frequency bands using integrated resource management and other mitigation techniques in a such a way as to minimise interference between both the systems, thus making optimum usage of valuable frequency spectrum.
