Abstract

Un método y aparato generan un libro de codigos y senalizacion de control y programacion asociada. Una pluralidad de combinaciones de canal es generada para una pluralidad de unidades inalámbricas de transmision/recepcion (WTRUs). El canal para cada WTRU es cuantizado en base al libro de codigos de WTRU. Un libro de codigos para conformacion de haz es generado para una pluralidad de WTRUs. El libro de codigos incluye una pluralidad de matrices de conformacion de haz, Todas las posibles matrices de conformacion de haz pueden ser calculadas y el libro de codigos puede ser cuantizado.
