Abstract

Los aspectos de la presente solicitud proporcionan métodos y dispositivos en una red de comunicación que ayudan a implementar medición de señal de referencia de sondeo (SRS) por múltiples celdas (es decir, celdas de servicio y celdas no de servicio, también conocidas como "celdas vecinas"), así como las NR LMU. Esta medición de SRS mejorada basada en múltiples mediciones de NR LMU y/o celda puede facilitar usos más beneficiosos, tal como posicionamiento basado en UL y movilidad basada en UL.
