Abstract
(EN)
A method by which a terminal operates in a wireless communication system, according to one embodiment, comprises the steps of: receiving time difference of arrival (TDoA) slots from anchor nodes (ANs); and measuring the position of the terminal by using the TDoA slots, wherein the TDoA slots include control information of the ANs and positioning reference signals (PRSs) of the ANs.
(FR)
Dans un mode de réalisation, l'invention concerne un procédé dans lequel un terminal fonctionne dans un système de communication sans fil, comprenant les étapes consistant : à recevoir de noeuds d'ancrage (AN) des intervalles de différence de temps d'arrivée (TDoA) ; et à mesurer la position du terminal au moyen des intervalles TDoA, ces derniers comprenant des informations de commande des noeuds d'ancrage et des signaux de référence de positionnement (PRS) desdits noeuds.
