Abstract

Se describen sistemas y metodologías que facilitan proporcionar una alta reutilización para transmitir señales de referencia, tales como señales de referencia de posicionamiento (PRS positioning reference signals) y señales de referencia de celda específica (CRS - celispecific reference signals), a fin de mejorar la escuchabilidad de las mismas para aplicaciones tales como trilateración y/o lo similar. En particular, las PRSs pueden transmitirse en subtramas de posicionamiento diseñadas o seleccionadas. Los elementos de recursos dentro de la subtrama de posicionamiento pueden seleccionarse para transmitir las PRSs y pueden evitar conflicto con regiones de control diseñado, elementos de recursos utilizados para transmitir señales de referencia de celda específica, y/o lo similar. Los elementos de recursos para transmitir PRSs pueden seleccionarse de acuerdo con un esquema de reutilización planeada o pseudo-aleatoria. Además, puede aplicarse un esquema de diversidad de transmisión a las. PRSs a fin de minimizar el impacto para introducir las PRSs a dispositivos de legado. Además, las porciones de una subtrama no diseñada para la transmisión de PRS pueden utilizarse para la transmisión de datos de plano de usuario.
