Abstract

La présente divulgation concerne un procédé de positionnement de groupe, un appareil, un dispositif et un support de stockage. Le procédé consiste en : en réponse à la détermination par un premier UE d'établir un positionnement de groupe de liaison latérale (SL) avec un groupe d'UE cible, le lancement d'une procédure de positionnement de groupe avec le groupe d'UE cible (201), le groupe d'UE cible comprenant au moins deux seconds UE. Le procédé de la présente divulgation peut permettre de réduire efficacement la signalisation d'interaction et d'augmenter l'efficacité d'interaction, ce qui permet d'augmenter l'efficacité de positionnement.
