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.

摘要： A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.
