Abstract
(EN)
The present disclosure relates to the technical field of communications, and more particularly, relates to a random access method and device, and a storage medium. The method is implemented by a first apparatus comprising n antenna panels, where n is an integer greater than or equal to 2. The method comprises: respectively transmitting random access preambles to a second apparatus by means of k of the n antenna panels; and respectively monitoring, by means of the k antenna panels, random access responses (RARs) returned by the second apparatus. In the present disclosure, k of n antenna panels of a first apparatus respectively transmit random access preambles thereof to a second apparatus, such that the first apparatus can initiate random access by means of different antenna panels of itself, thereby increasing the probability of transmitting the random access preambles when the first apparatus initiates random access, enhancing random access efficiency, and expanding application scenarios in which the first apparatus can initiate random access.

La présente invention concerne le domaine technique des communications, et concerne plus particulièrement un procédé et un dispositif d'accès aléatoire, ainsi qu'un support de stockage. Le procédé est mis en œuvre par un premier appareil comprenant n panneaux d'antenne, n étant un nombre entier supérieur ou égal à 2. Le procédé comprend les étapes consistant à : transmettre respectivement des préambules d'accès aléatoire à un second appareil au moyen de k des n panneaux d'antenne ; et surveiller respectivement, au moyen des k panneaux d'antenne, des réponses d'accès aléatoire (RAR) renvoyées par le second appareil. Dans la présente invention, k de n panneaux d'antenne d'un premier appareil transmettent respectivement des préambules d'accès aléatoire de ceux-ci à un second appareil, de telle sorte que le premier appareil peut déclencher un accès aléatoire au moyen de ses différents panneaux d'antenne, ce qui permet d'augmenter la probabilité de transmission des préambules d'accès aléatoire lorsque le premier appareil initie un accès aléatoire, d'améliorer l'efficacité d'accès aléatoire, et d'étendre des scénarios d'application dans lesquels le premier appareil peut déclencher un accès aléatoire.
