摘要：A wireless communication technique provides mobility for a mobile station ( 52 ) to communicate with an overlay network device ( 40 ), which is within a coverage area ( 34 ) of an underlay network device ( 24 ), when the mobile station ( 52 ) is within a coverage area ( 42 ) of both devices. The overlay network device ( 40 ) broadcasts at least two downlink channels. A cell code (e.g., a scrambling code or pseudo noise offset) of a first one of the downlink channels identifies an overlay network device ( 40 ) exclusively. The mobile station ( 52 ) can detect the first downlink channel responsive to an indication of the exclusive cell code from the underlay network device. A second one of the downlink channels allows for subsequent, ongoing communications between the mobile station and the overlay network device.
