Abstract

Se proporciona un método para operar un equipo de usuario en una comunicación inalámbrica como una modalidad o realización de la presente invención. El método puede incluir: recibir información de modulación y esquema de codificación (MCS) para cada una de dos o más palabras en clave o de código a partir de una estación base (BS); determinar un puerto de antena de señal de referencia de demodulación (DMRS) al que se asigna o mapea un puerto de antena de señal de referencia de seguimiento de fase (PTRS) en función de la información de MCS; y recibir una PTRS basada en el puerto de antena DMRS, en donde un puerto de antena DMRS con el índice más bajo entre uno o más puertos de antena DMRS incluidos en una palabra en clave o de código con el MCS más elevado entre las dos o más palabras en clave o de código se puede determinar como el puerto de antena DMRS.
