A method of determining the location of a user equipment includes determining a round trip time for downlink from at least three nodes to a user equipment, determining the transmission timing delay at the user equipment for the round trip time of each of the three nodes, and determining a distance from each of the at least three nodes using the round trip time and the transmission timing delay.
L'invention concerne un procédé de détermination de la localisation d'un équipement utilisateur. Ce procédé consiste à déterminer une durée totale du cycle pour liaison descendante, à partir de trois noeuds vers un équipement utilisateur, déterminant le délai de transmission au niveau de l'équipement utilisateur pour la durée totale du cycle pour au moins chacun des trois noeuds, au moyen de la durée totale de cycle et du délai de transmission.
