Abstract

Se divulgan un método y aparato para realimentación de canal de control rápido para operaciones de múltiples portadoras de enlace descendente. Una unidad inalámbrica de transmisión/recepción (WTRU) recibe senales sobre una pluralidad de portadoras de enlace descendente, genera una realimentación para cada una de la pluralidad de portadoras de enlace descendente sobre la base de las senales recibidas y transmite, a través de una pluralidad de antenas, la realimentación para al menos una de la pluralidad de portadoras de enlace descendente sobre un primer canal físico y una realimentación para otra de la pluralidad de portadoras de enlace descendente sobre un segundo canal físico.
