Title
(EN) POSITIONING TECHNIQUES USING POSITIONING REFERENCE SIGNALING
(FR) TECHNIQUES DE POSITIONNEMENT UTILISANT UNE SIGNALISATION DE RÉFÉRENCES DE POSITIONNEMENTS
Abstract
(EN) In some implementations, a method of wireless communication includes transmitting, from an initiator of a positioning reference signal (PRS) group to other members of the PRS group, an indication of access to a wireless channel for the PRS group. The method further includes broadcasting a first PRS via each antenna beam of a plurality of antenna beams. An antenna array of the initiator is configured to communicate via the plurality of antenna beams. Other aspects and features are also claimed and described.
(FR) Selon certains modes de réalisation, un procédé de communication sans fil consiste à transmettre, d'un initiateur d'un groupe de signaux de références de positionnements (PRS) à d'autres membres du groupe de PRS, une indication d'accès à un canal sans fil pour le groupe de PRS. Le procédé consiste en outre à diffuser un premier PRS par chaque faisceau d'antenne d'une pluralité de faisceaux d'antennes. Un réseau d'antennes de l'initiateur est configuré pour communiquer par la pluralité de faisceaux d'antennes. D’autres aspects et caractéristiques sont également revendiqués et décrits.
