Title
(EN) ON DEMAND POSITIONING IN A WIRELESS COMMUNICATION SYSTEM
(FR) OBTENTION D'INFORMATIONS DE POSITION À LA DEMANDE DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A method, performed in a wireless device, for obtaining position information of user equipment, UE, in a wireless communication system is described. The method includes transmitting, to a network, an indication comprising beam information defining beams that are suitable to be used for transmitting Positioning Reference Signals, PRS, to the wireless device, receiving, from the network, control signaling comprising PRS scheduling information for upcoming transmission of the PRS in beams, performing measurements on the PRS based on the PRS scheduling information that was received, and providing the measurements to the network.

L'invention concerne un procédé exécuté dans un dispositif sans fil pour obtenir des informations de position d'un équipement utilisateur (UE) dans un système de communication sans fil. Le procédé consiste à : transmettre à un réseau une indication contenant des informations de faisceau définissant des faisceaux pouvant être utilisés pour transmettre des signaux de référence de positionnement (PRS) au dispositif sans fil ; recevoir, du réseau, une signalisation de commande contenant des informations de planification de PRS pour une transmission consécutive des PRS dans des faisceaux ; exécuter des mesurages sur les PRS d’après les informations de planification de PRS reçues ; et fournir les mesurages au réseau.
