Abstract

La présente divulgation concerne un procédé et un appareil de réception de signal de référence, un procédé et un appareil d'envoi de signal de référence, un appareil de communication et un support de stockage. Le procédé de réception de signal de référence consiste à : déterminer des informations de ressource temps-fréquence, qui sont utilisées pour recevoir un signal de référence dans un état non connecté, le signal de référence étant différent d'un bloc de signal de synchronisation et PBCH (SSB) ; et, en fonction des informations de ressource temps-fréquence, recevoir le signal de référence à l'état non connecté. Dans la présente divulgation, un terminal peut déterminer des informations de ressource temps-fréquence, qui sont utilisées pour recevoir un signal de référence à un état non connecté, et après que le terminal entre à l'état non connecté, il peut recevoir le signal de référence en fonction des informations de ressource temps-fréquence. Du fait que le signal de référence est différent d'un SSB, c'est-à-dire que le terminal peut recevoir, à l'état non connecté, un signal de référence séparé du SSB, et peut ainsi exécuter une action à l'aide du signal de référence reçu, sans être limité à l'exécution d'une action selon le SSB, la flexibilité d'un terminal exécutant une action à un état non connecté et selon un signal de référence peut être améliorée.
