摘要： Aspects of a method and system for service mobility via a femtocell infrastructure are provided. In this regard, a mobile cellular enabled communication device may detect a femtocell operable to deliver content for one or more services to the mobile cellular enabled communication device, where the one or more services may be provided via a set-top-box communicatively coupled to the femtocell. The mobile cellular enabled communication device may communicate a user profile to the femtocell, wherein information in the profile may be utilized by the set-top-box to authenticate and/or authorize access to the services by the mobile cellular enabled communication device and thus the mobile cellular enabled communication device may receive the content from the set-top-box based on the authentication and/or authorization. The content may comprise voice, video, data, text and/or still images.

摘要： Methods and systems for processing signals in a receiver are disclosed herein and may comprise receiving spatially multiplexed signals via M receive antennas. A plurality of multiple data streams may be separated in the received spatially multiplexed signals to detect MIMO data streams. Each of the MIMO data streams may correspond to a spatially multiplexed input signal.

Complex waveforms, comprising in-phase (I) and quadrature (Q) components for the MIMO data streams within the received spatially multiplexed signals may be processed and the processed complex waveforms may be filtered to generate baseband bandwidth limited signals. Phase and/or amplitude for one or more received spatially multiplexed signals may be adjusted utilizing the estimated complex phase and amplitude. Phase and/or amplitude may be adjusted continuously and/or at discrete intervals.

摘要： Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.
