摘要： In a frequency division duplex wireless communications system, the wireless network independently and separately assigns RL and FL carrier frequencies to a mobile station, thereby supporting a variable duplex frequency separation. The assigned RL and FL carrier frequencies can be within the same frequency segment, in different frequency segments within a band class, or can be in different band classes. This feature is supported by new channel mapping and signaling.

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： A signaling method is provided that can improve the efficiency of forward-link control signaling in OFDM systems. The method involves using a set of forward-link subcarriers that are dedicated for control information, and are shared by a set of two or more users. The control information destined for each user is spread using a respective spreading code, thereby to provide a spread control message. The spread control messages destined for the various users are summed together prior to transmission.

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.
