Title
(EN) METHODS AND APPARATUSES FOR POSITIONING IN A WIRELESS COMMUNICATIONS NETWORK
(FR) PROCÉDÉS ET APPAREILS DE POSITIONNEMENT DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN) The present disclosure relates to methods and apparatuses for improving positioning of a device in a wireless communications network. In some embodiments, a method performed by a measuring device (201, 1300) configured to communicate with a positioning device (205, 1500), comprises: determining (1201) a cross-correlation between a received signal and a transmitted reference signal; determining (1202) a channel impulse response (CIR) of the cross-correlation related to a first lobe detected above a selected threshold in said CIR; and reporting (1203) information on a truncated part of the CIR around the first lobe to the positioning device (205, 1500) for enabling the positioning device (205, 1500) to correct or estimate a measurement related to a distance between a transmitter (202, 203, 204) and the measuring device (201, 1300) and/or a distance between at least one reflecting cluster and the measuring device (201, 1300).
(FR) La présente divulgation se rapporte à des procédés et à des appareils qui permettent d'améliorer le positionnement d'un dispositif dans un réseau de communication sans fil. Dans certains modes de réalisation, un procédé mis en œuvre par un dispositif de mesure (201, 1300) configuré de sorte à communiquer avec un dispositif de positionnement (205, 1500) consiste : à déterminer (1201) une corrélation croisée entre un signal reçu et un signal de référence émis ; à déterminer (1202) une réponse d'impulsion de canal (CIR) de la corrélation croisée associée à un premier lobe détecté au-dessus d'un seuil sélectionné dans ladite CIR ; à rapporter (1203) des informations sur une partie tronquée de la CIR autour du premier lobe au dispositif de positionnement (205, 1500) afin de permettre au dispositif de positionnement (205, 1500) de corriger ou d'estimer une mesure associée une distance entre un émetteur (202, 203, 204) et le dispositif de mesure (201, 1300) et/ou une distance entre au moins un groupe réfléchissant et le dispositif de mesure (201, 1300).
