Abstract

Se describen técnicas para comunicarse. por múltiples portadoras en una red de comunicaciones inalámbricas. En un aspecto, pueden utilizarse diferentes niveles de potencia de transmisión para diferentes portadoras a fin de atenuar la interferencia. A una primera estación puede asignársele una o más portadoras entre múltiples portadoras disponibles para la comunicación. A una segunda estación base pueden no asignársele una o más portadoras no asignadas a la primera estación base. Cada estación base puede comunicarse en cada portadora asignada en un primer nivel de potencia de transmisión (por ejemplo, plena) y puede comunicarse por cada portadora no asignada en un segundo nivel de potencia de transmisión más bajo (por ejemplo, menor). Las estaciones base primera y segunda pueden pertenecer a diferentes clases de potencia o soportar diferentes tipos de asociación. En otro aspecto, la información de control puede enviarse por una portadora designada para soportar la comunicación por múltiples portadoras. Aún en otro aspecto, una estación base puede transmitir información de bloqueo que indica el estado de las portadoras.
