Abstract

<p>La revelación se refiere en algunos aspectos a técnicas para Ia estimación de canal mejorada. Par ejemplo, un dispositivo puede especificar una estructura piloto donde Ia densidad piloto difiere en el tiempo. Como otro ejemplo, un dispositivo puede indicar que un piloto de un intervalo de tiempo de transmisión anterior (TTI) se puede utilizar para Ia estimación de canal. Como otro ejemplo, un dispositivo puede emplear bloque de recursos físicos dominio de Ia frecuencia (PRB) empaquetado con Ia información de señalización de empaquetado. Como otro ejemplo, un dispositivo puede utilizar una relación tráfico a piloto ajustable (TPR) para Ia optimización del rendimiento. Otros aspectos, realizaciones y características también se discuten y reivindican.</p>
