Abstract: 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. The mobile cellular enabled communication device may detect the femtocell by receiving one or broadcast messages from the femtocell.

Abstract: Aspects of a method and system for dynamic adjustment of power, antenna direction and frequencies in a femtocell network are provided. In this regard, a communication system may comprise a plurality of femtocells, one or more base stations, and a femtocell management entity that coordinates operation of the plurality of femtocells. One or more parameters may be communicated from one of the plurality of femtocells and/or one or more base stations to the femtocell management entity. The femtocell management entity may be enabled to utilize the one or more parameters to determine configuration information for one of the plurality of femtocells and/or for one or more remaining ones of the plurality of femtocells. One of the plurality of femtocells may be enabled to receive the determined configuration information from the femtocell management entity. One of the plurality of femtocells may be configured utilizing the received determined configuration information.

Abstract: Aspects of a method and system for channel estimation in a MIMO communication system with multiple RF chains for WCDMA/HSDPA may comprise receiving a plurality of communication signals from a plurality of transmit antennas. A plurality of vectors of baseband combined channel estimates may be generated based on phase rotation of the received plurality of communication signals. A matrix of processed baseband combined channel estimates may be generated based on the generated plurality of vectors of baseband combined channel estimates. A plurality of amplitude and phase correction signals may be generated based on the generated plurality of vectors of baseband combined channel estimates. An amplitude and a phase of at least a portion of the received plurality of communication signals may be adjusted based on the generated plurality of amplitude and phase correction signals, respectively.
