L'invention concerne un procédé et un appareil de configuration d'un espace de mesure permettant à un terminal de pouvoir mesurer les signaux de référence de plusieurs cellules voisines dans un intervalle de mesure. Le procédé comprend les étapes suivantes : un terminal reçoit des informations de configuration d'un dispositif réseau, les informations de configuration comprenant un intervalle de mesure ; l'intervalle de mesure étant M fois supérieur à une demi-trame ; la période, durant laquelle une cellule voisine d'une cellule de desserte où se trouve le terminal envoie des signaux de référence, étant une première période ; la première période étant N fois la demi-trame ; les positions candidates de tous les signaux de référence envoyés par la cellule voisine étant situées dans une demi-trame de la première période ; M étant premier avec N ; M et N étant des nombres entiers positifs ; et le terminal reçoit les signaux de référence de la cellule voisine dans l'intervalle de mesure selon les informations de configuration.
