Title (EN) AUTHENTICATING A MULTICAST WAKE-UP PACKET
(FR) AUTHENTIFICATION D'UN PAQUET DE RÉVEIL MULTIDIFFUSION
Abstract:
(EN) Embodiments of authenticating a multicast wake-up packet are generally described herein. A station (STA) encodes, for transmission to an access point (AP), an indication that a wireless local area network (WLAN) radio of the STA is being turned off and a request for a latest wake-up packet sequence number (SN). The STA decodes an indication of the latest wake-up packet SN. The STA signals for turning off the WLAN radio and turning on a wake-up receiver (WUR) of the STA. The STA decodes a wake-up packet received at the WUR. the STA determines, based on a message authentication code and a SN of the wake-up packet, and the latest wake-up packet SN, whether the wake-up packet came from the AP. The STA encodes a wake-up signal to the WLAN radio upon determining that the wake-up packet came from the AP.
(FR) Selon certains modes de réalisation, l'invention concerne généralement une authentification d'un paquet de réveil multidiffusion. Une station (STA) code, pour une transmission à un point d'accès (AP), une indication qu'une radio de réseau local sans fil (WLAN) de la STA est désactivée et une demande pour le dernier numéro de séquence (SN) de paquet de réveil. La STA décode une indication du dernier SN de paquet de réveil. La STA signale la désactivation de la radio WLAN et l'activation d'un récepteur de réveil (WUR) de la STA. La STA décode un paquet de réveil reçu au niveau du WUR. La STA détermine, sur la base d'un code d'authentification de message et d'un SN du paquet de réveil, et du dernier SN du paquet de réveil, si le paquet de réveil provient de l'AP. La STA code un signal de réveil à la radio WLAN lorsqu'il est déterminé que le paquet de réveil provient de l'AP.
