Abstract
(EN)
The present application provides a communication method, a network device and a terminal device. The method comprises: a network device determines a protection time unit and a single-carrier symbol, where the protection time unit is located in front of the single-carrier symbol and adjacent to the single-carrier symbol, the N control information units comprise the target control information unit, N is a positive integer greater than or equal to 1; the network device sends the protection time unit and the single-carrier symbol to the target terminal device. According to the technical solution, the protection time unit is located in front of the single-carrier symbol, so that the inter-symbol interference generated by a multi-path channel and the adverse effect caused by radio-frequency switching during beam switching on useful data can be reduced.

La présente invention concerne un procédé de communication, un dispositif de réseau et un dispositif terminal. Le procédé comprend les étapes suivantes : un dispositif de réseau détermine une unité de temps de protection et un symbole à porteuse unique, l'unité de temps de protection étant située devant le symbole à porteuse unique et adjacente au symbole à porteuse unique, les N unités d'informations de commande comprenant l'unité d'informations de commande cible, N étant un nombre entier positif supérieur ou égal à 1 ; le dispositif de réseau envoie l'unité de temps de protection et le symbole à porteuse unique au dispositif de terminal cible. Selon la solution technique, l'unité de temps de protection est située devant le symbole à porteuse unique, de sorte que l'interférence entre symboles générée par un canal à trajets multiples et l'effet indésirable provoqué par une commutation radiofréquence pendant une commutation de faisceau sur des données utiles puissent être réduits.
