  • Allocation method and apparatus for reusing network resources in a wireless communication system
    Patent number: 6597671
    Abstract: In a wireless communication system (106), base stations (118, 120) are connected to a backbone network (116) such as a wired LAN and act as access points and relays for remote stations (128, 132, 136). A remote station registers and performs bidirectional communication with one of the base stations designated as its home base station. Base stations have overlapping coverage areas where a remote station is within reception range of several base stations. Such communication system may for instance be a multicell radio LAN using frequency hopping signaling. The method allows to reuse a limited number of network resources such as frequency hopping patterns and assign the same resource to several active base stations.
    Type: Grant
