Title (EN) A WIRELESS DEVICE, A FIRST ACCESS NODE AND METHODS THEREIN
(FR) DISPOSITIF SANS FIL, PREMIER NŒUD D'ACCÈS ET PROCÉDÉS CORRESPONDANTS
Abstract:
(EN) A wireless device 206 and a method therein for enabling a single Random Access (RA) preamble to be received by a first Access Node (AN) 208 and by a second AN 210, which first and second ANs are asynchronous ANs. The wireless device, and the first and second ANs are operating in a wireless communications network 200. The wireless device receives a first signal from the first AN and a second signal from the second AN. Based on the received first and second signals, the wireless device determines an overlapping time window during which a transmission from the wireless device is receivable by the first and second ANs, and transmits a single RA preamble to the first and second ANs during the determined overlapping time window.
(FR) L'invention concerne un dispositif sans fil (206) et un procédé correspondant permettant à un préambule d'accès aléatoire (RA) d'être reçu par un premier nœud d'accès (AN) (208) et par un second AN (210), lesdits premier et second AN étant des AN asynchrones. Le dispositif sans fil et les premier et second AN sont exploités dans un réseau de communication sans fil (200). Le dispositif sans fil reçoit un premier signal en provenance du premier AN et un second signal en provenance du second AN. En fonction des premier et second signaux reçus, le dispositif sans fil détermine une fenêtre temporelle de chevauchement pendant laquelle une transmission en provenance du dispositif sans fil peut être reçue par les premier et second AN et transmet un préambule de RA unique aux premier et second AN pendant la fenêtre temporelle de chevauchement déterminée.
