Title
(EN) OPTIMIZED TRANSMISSION FOR SINGLE/DOUBLE-SIDED TWO-WAY RANGING AMONG MANY DEVICES
(FR) TRANSMISSION OPTIMISÉE DESTINÉE À UNE TÉLÉMÉTRIE BIDIRECTIONNELLE SIMPLE/DOUBLE FACE PARMI DE NOMBREUX DISPOSITIFS
Abstract
(EN)
A method of a transmit apparatus in a wireless communication system supporting ranging capability is provided. The method comprises: for a single-sided two-way ranging (SS-TWR), identifying a ranging round (RR) including a ranging initiation phase (RIP) for a set of transmit apparatuses including the transmit apparatus and a ranging response phase (RRP) for a set of receive apparatuses, wherein the RIP and the RRP comprise at least one slot; transmitting, to the set of receive apparatuses, a ranging initiation message in the RIP; and receiving, from one or more of the set of receive apparatuses, a ranging response message including information requested by the transmit apparatus in the RRP.
(FR)
L'invention concerne un procédé d'un appareil de transmission dans un système de communication sans fil prenant en charge une capacité de télémétrie. Le procédé consiste : pour une télémétrie bidirectionnelle simple face (SS-TWR), à identifier une boucle de télémétrie (RR) comprenant une phase de lancement de télémétrie (RIP) destinée à un ensemble d'appareils de transmission comprenant l'appareil de transmission et une phase de réponse de télémétrie (RRP) destinée à un ensemble d'appareils de réception, le RIP et le RRP comprenant au moins un intervalle ; à transmettre, à l'ensemble d'appareils de réception, un message de lancement de télémétrie dans le RIP ; et à recevoir, en provenance d'un ou plusieurs appareils parmi l'ensemble d'appareils de réception, un message de réponse de télémétrie comprenant des informations demandées par l'appareil de transmission dans le RRP.
