Abstract

Des modes de réalisation de la présente demande concernent un procédé de communication sans fil, un dispositif terminal, et un dispositif de réseau. Lorsqu'une transmission répétée d'un PDCCH est prise en charge sur la base d'un TCI unifié, une hypothèse de QCL d'un CORESET est correctement configurée en spécifiant le CORESET sur lequel un état TCI indiqué dans le PDCCH agit, de façon à assurer une réception correcte d'un canal ultérieur planifié sur la base du PDCCH. Le procédé de communication sans fil comprend les étapes suivantes : un dispositif terminal reçoit au moins un PDCCH, un espace de recherche associé à au moins un CORESET dans des CORESET pour envoyer l'au moins un PDCCH étant utilisé pour répéter la transmission du PDCCH et étant pourvu d'un TCI unifié ; et le dispositif terminal détermine, selon le PDCCH reçu, un CORESET sur lequel un état TCI indiqué dans l'au moins un PDCCH agit ou un groupe de CORESET auquel appartient le CORESET.
