Abstract
(EN)
Disclosed are a method and device for paging, for use in a high frequency NR system, preventing a paging message from being transmitted on all beams to ensure that all terminals within coverage can receive corresponding paging, thus saving downlink time frequency resources. The paging method provided in the present application comprises: transmitting to a terminal a paging indication used for indicating to the terminal whether a paging message is present; and when a random access preamble sequence transmitted by the terminal is received, transmitting the paging message to the terminal.
(FR)
L'invention concerne un procédé et un dispositif de radiomessagerie, destinés à être utilisés dans un système NR haute fréquence, empêchant un message de radiomessagerie d'être transmis sur tous les faisceaux afin d'assurer que tous les terminaux à l'intérieur de la couverture peuvent recevoir une radiomessagerie correspondante, économisant ainsi des ressources temps-fréquence de liaison descendante. Le procédé de radiomessagerie selon la présente invention consiste : à transmettre à un terminal une indication de radiomessagerie utilisée pour indiquer au terminal si un message de radiomessagerie est présent ; et lorsqu'une séquence de préambule d'accès aléatoire transmise par le terminal est reçue, à transmettre le message de radiomessagerie au terminal.
