Title (EN) METHODS, DEVICES AND NETWORK NODES FOR PERFORMING AN ACCESS PROCEDURE
(FR) PROCÉDÉS, DISPOSITIFS, ET NŒUDS DE RÉSEAU POUR EFFECTUER UNE PROCÉDURE D'ACCÈS
Abstract:
(EN) A method in a wireless device for performing an access procedure comprises: receiving an indication from a network node, the indication comprising an allocation of a plurality of Physical Random Access Channel (PRACH) resources for PRACH preamble transmission, wherein the plurality of PRACH resources comprises one of a first combination and a second combination of time resources, frequency resources and sequences, wherein the first combination comprises a plurality of time resources, one or more frequency resources and a first plurality of sequences and the second combination comprises one or more time resources, a plurality of frequency resources and a second plurality of sequences; and selecting a PRACH resource among the plurality of PRACH resources. A wireless device for performing this method is also disclosed.
(FR) L'invention concerne un procédé exécuté dans un dispositif sans fil pour effectuer une procédure d'accès. Le procédé consiste à : recevoir, d'un nœud de réseau, une indication contenant une attribution d'une pluralité de ressources de canal d'accès aléatoire physique (PRACH) pour une transmission de préambule PRACH, la pluralité de ressources PRACH comprenant l'une d'une première combinaison et d'une seconde combinaison de ressources temporelles, de ressources fréquentielles, et de séquences, la première combinaison comprenant une pluralité de ressources temporelles, une ou plusieurs ressources fréquentielles et une première pluralité de séquences, et la seconde combinaison comprenant une ou plusieurs ressources temporelles, une pluralité de ressources fréquentielles et une seconde pluralité de séquences; et sélectionner une ressource PRACH parmi la pluralité de ressources PRACH. L'invention concerne également un dispositif pour exécuter le procédé.
