Abstract

L'invention, selon certains modes de réalisation représentatifs, fait appel à des appareils, à des systèmes et/ou à des procédés de rétroaction de rapport de mesure d'emplacement (LMR). Par exemple, un appareil peut comprendre une logique et des circuits configurés pour amener une première station sans fil à traiter au moins une trame de sondage de canal à partir d'au moins une seconde station de communication sans fil ; pour déterminer une ou plusieurs mesures de distance sur la base de la trame de sondage de canal ; et pour transmettre une trame de rétroaction de LMR à la seconde station de communication sans fil, la trame de rétroaction de LMR comprenant la ou les mesures de distance, et une indication du fait que la trame de rétroaction de LMR ne doit pas faire l'objet d'un accusé de réception par une trame d'accusé de réception (Ack).
