Abstract

Una estación base incluye una primera unidad que realiza transmisión por radio de una señal a una terminal, una segunda unidad, y una interfaz que conecta la primera unidad a la segunda unidad. Con el propósito de determinar cual de la primera unidad y la segunda unidad es una unidad que realiza la precodificación, la información que indica si por lo menos una de la primera unidad y la segunda unidad tiene o no una función de precodificación se envía a través de la interfaz.
