Abstract

Se proporcionan un método y un aparato para la cooperacion de multiceldas cuando las celdas multiples están cooperando para transmitir datos a una pluralidad de unidades de transmision/recepcion inalámbrica (WTRU) y cada celda está utilizando una matriz de precodificacion comun . EL nivel de informacion intercambiado entre las celdas puede depender de la arquitectura de cooperacion particular. Las celdas pueden compartir informacion tal como la informacion del estado del canal (CSI), un indicador de la calidad del canal (CQI) o ambos. Las celdas pueden compartir indicaciones de clasificacion informadas por las WTRU. Las celdas también pueden compartir los datos que se están transmitiendo a las WTRU. El método y aparato pueden también determinar los vectores de precodificacion para precodificacion de bucle cerrado, un CQI, CSI y clasificacion y codificacion y codificacion distribuida en espacio-tiempo/frecuencia con cooperacion de multiceldas. El método y aparato también pueden llevar a cabo un pedido de repeticion automático híbrido (HARQ) con cooperacion de multiceldas y senalizacion de control del enlace descendente.
