Abstract:
Un esquema de calibración de potencia ajusta los niveles de potencia de la red de femtoceldas basado en macro señales observadas en diferentes puntos en y alrededor de un área de cobertura y basado en las posiciones mutuas de las femtoceldas (p.ej., basado en señales de femtoceldas observadas en estos puntos). Por lo tanto, el esquema de calibración de potencia facilita un buen equilibrio entre proveer un nivel deseado de cobertura y mitigar la interferencia de macroceldas y femtoceldas cercanas.

Abstract:
A base station includes a base unit and a plurality of remote antenna units (RAUs). Each of the RAUs includes a physical layer circuit (PHY). The PHYs are configured to each use the same physical layer identifier, but each PHY includes its own hardware for supporting users in the coverage area of that PHY. The base unit controls resource allocation for the RAUs to increase the capacity of the base station and/or reduce interference between PHYs.
Abstract:
Transmit power management for small cells in a wireless communication environment may be achieved by receiving information generated by a plurality of access terminals associated with an access point, categorizing the access terminals based on the received information, and determining transmit power for the access point based on the categorization of the access terminals.
Abstract:
Provided are methods and apparatus for selecting a communication channel. The methods and apparatus select a channel having the least interference and minimize a number of different channels in use. For example, a method for selecting a communication channel includes measuring a transmission characteristic for each channel in a plurality of channels to create a transmission characteristic measurement for each channel. The method also includes receiving, from at least one neighboring access point, data indicating the neighboring access point uses a channel in the plurality of channels. A utility value for each channel in the plurality of channels is calculated by weighting, based on the number of the neighboring access points using each channel in the plurality of channels, the transmission characteristic measurement for each channel in the plurality of channels. Further, the channel having the highest or the lowest utility value is chosen as the communication channel.
