Abstract
(EN) Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a terminal device comprises receiving, from a network node, information indicating an association between a downlink transmission and an uplink transmission (e.g. an association between a synchronization signal and physical broadcast channel block and a shared channel occasion) in a random access procedure. The association is based at least in part on configuration of random access resource (e.g. a random access occasion) and shared channel resource (e.g. the shared channel occasion) for an uplink message (e.g. including a preamble and physical uplink shared channel data) in the random access procedure. According to the embodiments of the present disclosure, an association between a synchronization signal and physical broadcast channel block and a shared channel occasion in a random access procedure can be configured flexibly and efficiently.
(FR) Divers modes de réalisation de la présente invention concernent un procédé d'accès aléatoire. Le procédé qui peut être implémenté par un dispositif terminal consiste à recevoir, en provenance d'un nœud de réseau, des informations indiquant une association entre une transmission de liaison descendante et une transmission de liaison montante (par exemple une association entre un bloc de signal de synchronisation et de canal de diffusion physique et une opportunité de canal partagé) dans une procédure d'accès aléatoire. L'association est basée au moins en partie sur la configuration d'une ressource d'accès aléatoire (par exemple une opportunité d'accès aléatoire) et une ressource de canal partagé (par exemple l'opportunité de canal partagé) pour un message de liaison montante (contenant par exemple un préambule et des données de canal partagé de liaison montante physique) dans la procédure d'accès aléatoire. Selon les modes de réalisation de la présente invention, une association entre un signal de synchronisation et un bloc de signal de synchronisation et de canal de diffusion physique et une opportunité de canal partagé dans une procédure d'accès aléatoire peut être configurée de manière flexible et efficace.
