Abstract

La présente invention concerne un procédé de communication, un dispositif, et une puce, qui sont utilisés pour fournir un mécanisme destiné à un appareil de communication afin de rapporter une capacité d'espace nul. Lorsqu'un appareil de communication est déterminé pour avoir une capacité d'espace nul, une signalisation de capacité de terminal, une demande de transfert intercellulaire de cellule ou un message d'achèvement de reconfiguration de commande de ressource radio (RRC) est utilisé pour indiquer à un dispositif réseau que l'appareil de communication a une capacité d'espace nul. Le procédé et l'appareil de l'invention peuvent être appliqués à une conduite sans conducteur, à l'intelligence artificielle et à des domaines similaires de communication sans fil.
