Abstract[English]
A method (40) of a first radio node (UE1), comprising: transmitting (41), from the first radio node (UE1), sidelink position reference signal configuration (SPRS configuration, 72, 83) defining at least one position reference signal to be transmitted from a first radio node (UE1) to the second radio node (UE2); generating (42) at least one position reference signal as defined by the SPRS configuration transmitted to the second radio node (UE2); performing (43) channel contention (LBT) for the purpose of position reference signal transmission in a bandwidth range at least partially comprised in an unlicensed radio band (F2), wherein the contention is performed using a listen before talk mechanism; based on a positive result of the channel contention, accessing (44) the channel for the duration of a channel on time; and transmitting (45) the at least one position reference signal to the second radio node (UE2) during the channel on time.[French]
L'invention concerne un procédé (40) d'un premier nœud radio (UE1), comprenant : la transmission (41), à partir du premier nœud radio (UE1), de la configuration de signal de référence de position de liaison latérale (configuration SPRS, 72, 83) définissant au moins un signal de référence de position à transmettre d'un premier nœud radio (UE1) au second nœud radio (UE2) ; la génération (42) d'au moins un signal de référence de position tel que défini par la configuration SPRS transmise au second nœud radio (UE2) ; la réalisation (43) d'une contention de canal (LBT) aux fins de la transmission du signal de référence de position dans une plage de largeur de bande au moins partiellement comprise dans une bande radio sans licence (F2), la contention étant réalisée à l'aide d'un mécanisme d'écoute avant de parler ; sur la base d'un résultat positif de la contention de canal, l'accès (44) au canal pendant la durée d'activation du canal ; et la transmission (45) de l'au moins un signal de référence de position au deuxième nœud radio (UE2) pendant la durée d'activation du canal.
