摘要： In a wireless telecommunications network, there is included: a macro cell (10) having a first coverage area; and at least one metro cell (20a, 20b, 20c) having a second coverage area, the metro cell being located within the first coverage area of the macro cell. Suitably, the macro cell is configured to: determine whether or not the macro cell is congested; determine whether or not the metro cell is uncongested; and, if it is determined the macro cell is congested and that the metro cell is uncongested, then the macro cell determines that an attempted application of Cell Association Bias (CAB) for the metro cell is warranted. Suitably, if CAB is in fact applied, the macro cell also implements enhanced Inter Cell Interference Coordination (eICIC) using Almost Blank Subframes (ABS) and informs its other neighboring metro cells of this configuration.

摘要： A method is provided a wireless system for providing an interference suppression zone in a portion of the macro cell coverage area bordering the small-cell coverage area for a small cell, but outside that small-cell coverage area. The transmission power of a UE located within the interference suppression zone is minimized to minimize the inter-cell interference to the small cells. The invention methodology further operates to enhance the redirection/redistribution methods of the art for UEs located in the interference suppression zone, further reducing macro to small cell interference. In further embodiments of the invention, methods are provided for determining the scope of an interference suppression zone and for determining proximity of an UE to the interference suppression zone.

摘要： In a method for controlling access to wireless resources provided by femto cells within a femto subnet a femto management system or radio access network may control access to femto cells within the femto subnet by assigning at least one hashing class mask of a first-type or hashing class mask of a second-type to a wireless user. The hashing class mask of the first-type or hashing of the second-type class mask may be assigned based on whether the wireless user is authorized to access a first femto cell within the femto subnet. The hashing class mask of the first-type provides access to at least one first femto cell within the femto subnet.
