    Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

    Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a re-ceiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may au-tonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibra-tion process.

    Abstract: Una portadora para una femto-celda se selecciona de un conjunto de portadoras disponible para las femto-celdas. El femto-nodo determina un orden de preferencia para el conjunto y mide la resistencia de señal recibida (RSS) para cada portadora. El femto-nodo determina una portadora con menor interferencia portadora del conjunto con base en la RSS para cada portadora, luego define una portadora seleccionada para la femto-celda al comparar la RSS de la portadora con menor interferencia con la RSS de otras portadoras en el conjunto. La portadora seleccionada puede tener una RSS mayor que o igual a la RSS de la portadora con menor interferencia compensada por un margen predefinido. Las comparaciones pueden realizarse en el orden de preferencia. El conjunto disponible para los femto-nodos puede ser un subconjunto de todas las portadoras disponibles para una combinación de femto-celdas y macro celdas y una o más de las portadoras disponibles para las femto-celdas también puede ser una portadora disponible para macro-celdas.

    Abstract: A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.

    Abstract: The present disclosure presents a method and an apparatus for optimizing coverage area of a small cell. For example, the disclosure presents a method for estimating an available backhaul capacity of a small cell and determining a target OTA data rate for the small cell based at least on the estimated available backhaul capacity, and changing a coverage area of the small cell based at least on the determined target OTA data rate by. As such, optimizing coverage area of a small cell may be achieved.
