Les modes de réalisation de la présente demande concernent un procédé de configuration de diffusion de positionnement et un appareil de communication susceptibles d'optimiser un processus de configuration d'un signal de référence de positionnement en liaison montante de façon à économiser des ressources de réseau. Au cours du procédé, un élément de réseau de gestion de positionnement génère un bloc d'informations de système de positionnement (posSIB) et envoie un premier message à un premier dispositif de réseau d'accès. Le premier message contient le posSIB. Le premier message est utilisé pour ordonner au premier dispositif de réseau d'accès d'envoyer le posSIB. Le posSIB contient des premières informations de configuration de SRS correspondant au premier dispositif de réseau d'accès. Les premières informations de configuration de SRS contiennent une ou plusieurs informations de configuration de SRS parmi des informations de configuration de SRS candidates. Les informations de configuration de SRS candidates contiennent des informations de configuration d'un SRS qui est censé être reçu par chaque dispositif de réseau d'accès parmi au moins un dispositif de réseau d'accès. Le premier dispositif de réseau d'accès est un dispositif de réseau d'accès déterminé parmi ledit au moins un dispositif de réseau d'accès.
