Abstract

Se describen un método y aparato para la rápida retroalimentación de canal de control para múltiples operaciones de transmisor de enlace descendente. Una unidad de transmisión/recepción inalámbrica (WTRU) recibe señales sobre una pluralidad de transmisores de enlace descendente, genera retroalimentación para cada uno de la pluralidad de transmisores de enlace descendente basados en las señales recibidas, y transmite por medio de una pluralidad de antenas, la retroalimentación por al menos uno de la pluralidad de los transmisores de enlace descendente sobre un primer canal físico y la retroalimentación por otro de la pluralidad de transmisores de enlace descendente sobre un segundo canal físico.
