Abstract
(EN)
Some aspects described herein relate to receiving a configuration defining resources for transmitting a first message in a two-step random access procedure, wherein the first message includes a random access preamble and a payload, generating a beacon signal for transmitting as the first message, where the beacon signal includes one or more parameters to facilitate discovery by other UEs for pairing in sidelink communications, and transmitting, based on the configuration, the beacon signal as the first message over the resources.
(FR)
La présente invention concerne, selon certains aspects, la réception d'une configuration qui définit des ressources pour transmettre un premier message dans une procédure d'accès aléatoire à deux étapes, le premier message comprenant un préambule d'accès aléatoire et une charge utile, la génération d'un signal de balise pour la transmission en tant que premier message, le signal de balise comprenant un ou plusieurs paramètres pour faciliter la découverte par d'autres UE pour un appariement dans des communications de liaison latérale, et la transmission, sur la base de la configuration, du signal de balise en tant que premier message par l'intermédiaire des ressources.
