Abstract

Se dan a conocer un método, sistema y aparato para actualizaciones de filtros espaciales comunes para sistemas multi-TRP a base de multi-DCI. Se proporciona un método implementado por un nodo de red. Se determina al menos un recurso de enlace descendente para transmisión, en donde el por lo menos un recurso de enlace descendente pertenece a un primer CORESET de una pluralidad de CORESETs, que está asociado con un índice de grupo de CORESETs respectivo. La por lo menos una primera señal de enlace descendente se transmite al dispositivo inalámbrico en el por lo menos un recurso de enlace descendente determinado. Se transmite al menos una segunda señal de enlace descendente, en donde el dispositivo inalámbrico recibe la por lo menos una segunda señal de enlace descendente en función de un parámetro de QCL, asociado con el índice de grupo de CORESETs. El dispositivo inalámbrico transmite al menos una señal de enlace ascendente con base en un primer filtro de dominio espacial que está asociado con el índice de grupo de CORESETs.
