Abstract
(EN)
A positioning estimate for a user equipment (UE) is determined based on a combination of uplink-based positioning and downlink-based positioning. Positioning measurements based on downlink signals and uplink signals can be utilized to determine the positioning estimate. The positioning estimate may be computed by the UE or a node of a wireless communications network. This positioning scheme can include two parts, where a first part and second part are either uplink-based or downlink-based, but the two parts are different from each other. Positioning measurements performed in the first part may be sent along with reference signals in the second part.
(FR)
Selon la présente invention, une estimation de positionnement concernant un équipement utilisateur (UE) est déterminée sur la base d'une combinaison d'un positionnement basé sur la liaison montante et d'un positionnement basé sur la liaison descendante. Des mesures de positionnement basées sur des signaux de liaison descendante et des signaux de liaison montante peuvent être utilisées afin de déterminer l'estimation du positionnement. L'estimation du positionnement peut être calculée par l'UE ou par un nœud d'un réseau de communication sans fil. Ce système de positionnement peut comprendre deux parties, une première partie et une seconde partie étant basées soit sur la liaison montante, soit sur la liaison descendante, mais les deux parties étant différentes l'une de l'autre. Des mesures de positionnement effectuées dans la première partie peuvent être envoyées conjointement avec des signaux de référence dans la seconde partie.
