Abstract
(EN)
Embodiments disclosed herein can enable multi-TRP transmission for PDCCH to achieve diversity gain for the potential benefits to URLLC use cases with challenging reliability/robustness requirements. Specifically, multi-TRP transmission for PDCCH can be performed at different levels as follows: 1. PDCCH with multi-TRP transmission on repetition level; 2. PDCCH with multi-TRP transmission on CCE level; and/or 3. PDCCH with multi-TRP transmission on REGB level.

Des modes de réalisation de la présente invention peuvent permettre une transmission multi-TRP pour un PDCCH en vue d'obtenir un gain de diversité pour les avantages potentiels par rapport à des cas d'utilisation d'URLLC avec des exigences pointues en termes de fiabilité/robustesse. En particulier, une transmission multi-TRP pour un PDCCH peut être effectuée à différents niveaux de la manière suivante : 1. PDCCH avec une transmission multi-TRP sur un niveau de répétition ; 2. PDCCH avec une transmission multi-TRP sur le niveau CCE ; et/ou 3. PDCCH avec transmission multi-TRP sur le niveau REGB.
