Abstract

Se describe un método y aparato para transportar reportes de retroalimentación desde una parte receptora de datos (300) para datos recibidos desde un parte emisora de datos (302) en una conexión inalámbrica. Una pluralidad de recursos de retroalimentación (304) asignados a diferentes códigos de información de retroalimentación está reservada para la parte receptora de datos para transmitir los reportes de retroalimentación. Después de verificar si los datos se recibieron correctamente o no, la parte receptora de datos selecciona un recurso de retroalimentación (FR2) con un código que información de retroalimentación que corresponde a uno o más reportes de retroalimentación en los datos recibidos. La parte receptora de datos envía entonces información de retroalimentación en el recurso de retroalimentación seleccionado a la parte emisora de datos, transportando con esto el código de información de retroalimentación correspondiente. De este modo, se pueden transportar reportes de retroalimentación múltiples en un recurso de retroalimentación simple a la parte emisora de datos mientras aún retiene las propiedades de portador simple.
