Abstract
(EN)
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus may transmit a message in a first subset of a set of resources. The message may include a position of the apparatus and a resource ID indicating at least one symbol in a second subset of the set of resources for transmitting a sequence. The apparatus may transmit the sequence in the at least one symbol in the second subset of the set of resources identified by the resource ID, receive at least one other sequence, adjust a transmission timing based on the received at least one other sequence, and transmit, based on the adjusted transmission timing, the sequence in one or more symbols in a third subset of the set of resources.

La présente invention concerne un procédé, un appareil et un produit-programme d'ordinateur destinés aux communications sans fil. L'appareil peut être un équipement utilisateur (UE). L'appareil peut transmettre un message dans un premier sous-ensemble d'un ensemble de ressources. Le message peut comprendre une position de l'appareil et un identifiant de ressource indiquant un ou plusieurs symboles dans un deuxième sous-ensemble de l'ensemble de ressources afin de transmettre une séquence. L'appareil peut transmettre la séquence par l'intermédiaire du ou des symboles dans le deuxième sous-ensemble de l'ensemble de ressources identifié par l'ID de ressource, recevoir une ou plusieurs autres séquences, ajuster la temporisation de transmission sur la base de la ou des autres séquences reçues et transmettre, sur la base de la temporisation de transmission ajustée, la séquence dans un ou plusieurs symboles dans un troisième sous-ensemble de l'ensemble de ressources.
