Abstract

Se divulgan sistemas y métodos relativos a un procedimiento de acceso aleatorio basado en contención (CBRA) para la recuperación de fallos de haz (BFR). En algunas formas de realización, un método ejecutado por un dispositivo inalámbrico para la BFR en un sistema de comunicaciones inalámbricas comprende detectar un fallo de haz y, al hacerlo, implementar un procedimiento CBRA, donde implementar el procedimiento CBRA comprende proporcionar, a un nodo de red, una indicación explicita y/o implícita de: un motivo del procedimiento de acceso aleatorio basado en contención que es la recuperación de fallos de haz; un nuevo haz servidor del dispositivo inalámbrico; y una identidad de este último.
