Abstract

La présente divulgation se rapporte au domaine des communications, et concerne un procédé et un système de détection de communication et un dispositif associé. Le procédé consiste à : utiliser une pluralité de symboles de communication de liaison descendante dans un créneau temporel spécifique d'un signal de communication pour mesurer grossièrement un faisceau large cible où se trouve un objet cible ; si le faisceau large cible existe, multiplexer des symboles d'émission de détection sur les symboles de communication de liaison descendante devant un symbole d'intervalle de garde dans le créneau temporel spécifique, pour envoyer un flux de données combiné d'un flux de données du signal de communication et d'un flux de données d'un signal de détection obtenu sur la base d'un précodage combiné et d'une formation de faisceau combiné ; et pendant le symbole d'intervalle de garde dans le créneau temporel spécifique, utiliser des symboles de réception de détection pour la réception de détection, pour détecter un faisceau étroit cible où se trouve l'objet cible. Le procédé selon la présente divulgation peut améliorer l'utilisation de ressources sans fil, et fournir des capacités de détection dans une couverture pleine zone avec un impact minimal sur les performances du réseau de communication, fournissant des services de détection supplémentaires à un coût relativement bas.
