Abstract

En la presente descripción se describen sistemas, dispositivos y métodos para operar en una banda sin licencia. En un ejemplo, un dispositivo puede recibir información de configuración que incluye un tiempo máximo de ocupación de canal (MCOT, por sus siglas en inglés) y una pluralidad de parámetros que incluyen una pluralidad de ventanas de oportunidad de transmisión (TOW, por sus siglas en inglés). Con base en la información de configuración, el dispositivo puede dividir una transmisión en una pluralidad de ráfagas que pueden agruparse en conjuntos de ráfagas con base en cuántas ráfagas entran dentro de una TOW. El número de ráfagas en un conjunto de ráfagas puede ser menor que o igual al MCOT. El dispositivo puede realizar una evaluación de canal libre (CCA, por sus siglas en inglés) para determinar si el canal está ocupado y para determinar un tiempo de inicio dentro de la TOW para las ráfagas. Después, el dispositivo puede transmitir el conjunto de ráfagas para esa TOW, donde cada ráfaga puede tener un indicador de ráfaga (BI).
