摘要： At least one example embodiment discloses a method of controlling a handover of a user equipment (UE) from a serving base station to a target base station in a heterogeneous network. The method includes determining, by a serving base station, a speed of the UE and a type of the handover, the type of the handover being one of macro cell to macro cell, macro cell to small cell, small cell to macro cell and small cell to small cell, and controlling, by the serving base station, the handover from the serving base station to the target base station based on the speed of the UE and the type of handover.

摘要： A method is provided a wireless system for providing small “guard” cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB. By deploying small public “guard” cells in the macro cell proximate to the private HeNB cells, such a public mobile terminal is enabled to communicate with the public small cell at generally lower power than would have been necessary for communication with the distant macro eNB, with a resulting reduction in interference for the nearby HeNB cell. The FL interference between the macro cell and the HeNBs is also mitigated.

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： An enhanced access terminal (AT) that can serve as a “proxy wireless over-the-air backhaul or relay” is provided, to connect a base station with no backhaul to its neighboring fully functional base station that is connected to the NMS. In a further embodiment, an architecture and protocol for storing and retrieving data at the base station lacking backhaul is provided, and, using that information, a mechanism by which the ATR can communicate the format information to the source to improve interference cancellation at the base station lacking backhaul, and neighboring base stations, due to backhaul transmission from the AT's routing and relaying capability.

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.
