Abstract
(EN)
According to one aspect of the disclosure, a location node configured to communicate with a wireless device is provided. The location node includes processing circuitry configured to: receive spatial information; determine the wireless device relationship between a first reference station and a second reference station based at least in part on the spatial information; compare a first integer ambiguity level of the first reference station with a second integer ambiguity level of the second reference station, the second reference station corresponding to a current reference station of the wireless device; and transmit an indication of an applicability of the first integer ambiguity level of the first reference station to the second integer ambiguity level of the second reference station for position estimation, the indication being based on the comparison of the first integer ambiguity level with the second integer ambiguity level.

Un aspect de la présente invention concerne un nœud de localisation configuré pour communiquer avec un dispositif sans fil. Le nœud de localisation comprend des circuits de traitement configurés pour : recevoir des informations spatiales ; déterminer la relation de dispositif sans fil entre une première station de référence et une seconde station de référence sur la base, au moins en partie, des informations spatiales ; comparer un premier niveau d'ambiguïté de nombre entier de la première station de référence à un second niveau d'ambiguïté de nombre entier de la seconde station de référence, la seconde station de référence correspondant à une station de référence actuelle du dispositif sans fil ; et transmettre une indication d'une applicabilité du premier niveau d'ambiguïté de nombre entier de la première station de référence au second niveau d'ambiguïté de nombre entier de la seconde station de référence pour une estimation de position, l'indication reposant sur la comparaison du premier niveau d'ambiguïté de nombre entier au second niveau d'ambiguïté de nombre entier.
