Abstract

La presente invención se refiere a un aparato de usuario que se proporciona con una pluralidad de antenas, y transmite una señal de referencia en el enlace ascendente conmutando la pluralidad de antenas. La pluralidad de antenas están asociadas con los subcuadros transmitidos en el enlace ascendente. El aparato de estación base en un sistema de radio comunicación al cual se aplica diversidad de transmisión en el enlace ascendente incluye: una unidad de almacenamiento de nivel de recepción configurada para almacenar un nivel de recepción medido de la señal de referencia para cada antena de cada aparato de usuario; y un programador configurado para realizar, con base en el nivel de recepción de la señal de referencia transmitida para cada antena de cada aparato de usuario almacenado en la unidad de almacenamiento de nivel de recepción, la programación para determinar que un aparato de usuario se asigna a un subcuadro asociado con la antena.
