Abstract
Comprende una unidad de control que, en los casos en que se cumplen ambas condiciones (1) y (2), determina una suposicion de QCL para una senal de referencia de informacion de estado de canal aperiodica ( AP-CSI-RS) sobre la base de un conjunto de recursos de control (CORESET) con un CORESET-ID especifico en la ultima ranura en la que se supervisan uno o mas CORESET (1) el desplazamiento de programacion entre la recepcion del AP-CSI -RS y la recepcion de un canal de control de enlace descendente que transmite informacion de control de enlace descendente para programar el AP-CSI-RS es menor que el valor del periodo informado para la conmutacion de haces, y (2) en los mismos simbolos que el AP-CSI- RS, no hay otra senal de enlace descendente con un estado TCI indicado, o hay otra senal de enlace descendente sin un estado TCI indicado);y una unidad de recepcion que recibe el citado AP-CSI-RS utilizando el supuesto QCL.
