Abstract

Un método para multidifusión de un paquete comienza al proporcionar un regulador para cada uno de dos equipos de usuario (UEs) en comunicación con una estación base. Se hace una determinación si existe un paquete previamente sin enviar a la estación base. Se hace una segunda determinación si ambos reguladores de UE no se encuentran vacíos. Un regulador no vacío se nivela si no existe un paquete previamente sin enviar y si uno de los reguladores no está vacío. Se selecciona un paquete para ser transmitido si existe un paquete previamente sin enviar o si ambos reguladores no se encuentran vacíos. Los reguladores se actualizan en base a la retroalimentación recibida de los UEs.
