Abstract

Se describen técnicas para mitigar la interferencia en canales control en una red de comunicaciones inalámbricas. En un aspecto, la alta interferencia a través de los recursos de radio utilizados para un canal control se puede mitigar al enviar una solicitud para reducir la interferencia hacia una o más estaciones de interferencia. Cada estación de interferencia puede reducir su potencia de transmisión a través de los recursos de radio, lo cual entonces puede permitir que el canal control observe menos interferencia. En un diseño, un equipo de usuario (UE) puede detectar alta interferencia a través de los recursos de radio utilizados para un canal control mediante una estación base deseada. El UE puede enviar una solicitud para reducir la interferencia a través de los recursos radio hacia una estación base de interferencia, lo cual puede reducir su potencia de transmisión a través de los recursos de radio. El UE puede recibir el canal control a través de los recursos de radio provenientes de la estación base deseada y puede observar menos interferencia proveniente de la estación base de interferencia.
