Abstract

Varios métodos y aparatos proporcionan una adquisición de datos de canal de unidifusión, tal como la información de antenas, de subtramas del Servicio de Difusión y Multidifusión Multimedia (MBMS). Se describe un método para operar una entidad de infraestructura de redes de comunicación inalámbrica que comprende definir una subtrama (400) de una red de frecuencia única de difusiónmultidifusión (MBSFN) que comprende un símbolo (401) de unidifusión en una primera posición del símbolo predeterminada dentro de la subtrama (400), el símbolo (401) de unidifusión comprende por lo menos un primer símbolo de referencia de antena de unidifusión; definir una segunda posición (403) de símbolo dentro de una subtrama (400) para contener por lo menos un segundo símbolo de referencia de antena de unidifusión; y transmitir las subtrama (400) en donde el símbolo (401) de unidifusión comprende por lo menos un primer símbolo de referencia de antena de unidifusión y en donde el símbolo (403) de multidifusión comprende por lo menos el segundo símbolo de referencia de antena de unidifusión.
