Abstract:
(EN) A method for operating an STA in a WUR mode in a WLAN system according to an embodiment of the present invention may comprise the steps of: entering a duty cycle WUR mode for periodically turning on/off a WUR; monitoring, for a first time interval, a WUR signal transmitted to the STA or another STA by an AP with which the STA has been associated in a PCR mode; and when the WUR signal is not detected within the first time interval, switching from the duty cycle WUR mode to a normal WUR mode in which the WUR remains turned on all the time, and then monitoring the WUR signal transmitted by the AP, for a second time interval, wherein the STA returns to the duty cycle WUR mode when the WUR signal transmitted by the AP is detected within the second time interval, or scans the AP through PCR when the WUR signal transmitted by the AP is not detected within the second time interval.
(FR) Un procédé pour faire fonctionner une STA dans un mode de WUR dans un système WLAN selon un mode de réalisation de la présente invention peut comprendre les étapes suivantes : entrer dans un mode de WUR de cycle de service pour activer/désactiver périodiquement un WUR ; surveiller, pendant un premier intervalle de temps, un signal de WUR transmis à la STA ou à une autre STA par un AP avec lequel la STA a été associée dans un mode de PCR ; et lorsque le signal de WUR n'est pas détecté pendant le premier intervalle de temps, passer du mode de WUR de cycle de service à un mode de WUR normal dans lequel le WUR reste activé tout le temps, puis surveiller le signal de WUR transmis par l'AP, pendant un deuxième intervalle de temps, la STA revenant au mode de WUR de cycle de service lorsque le signal de WUR transmis par l'AP est détecté pendant le deuxième intervalle de temps, ou balaye l'AP par PCR lorsque le signal de WUR transmis par l'AP n'est pas détecté pendant le deuxième intervalle de temps.
(KO) 본 발명의 일 실시예에 따른 WLAN 시스템에서 STA이 WUR 모드로 동작하는 방법은, 주기적으로 WUR 수신기를 온/오프하는 듀티 사이클 WUR 모드로 들어가는 단계; 상기 STA이 PCR 모드에서 어소시에이션하였던 AP가 상기 STA 또는 다른 STA으로 송신하는 WUR 신호를 제1 시간 동안 모니터링하는 단계; 및 상기 제1 시간 내에 상기 WUR 신호가 검출되지 않는 경우, 상기 듀티 사이클 WUR 모드로부터 상기 WUR 수신기가 항상 켜지는 일반 WUR 모드로 천이하여, 상기 AP가 송신하는 상기 WUR 신호를 제2 시간 동안 모니터링하는 단계를 포함하고, 상기 STA은 상기 제2 시간 내에 상기 AP가 송신하는 상기 WUR 신호가 검출되면 상기 듀티 사이클 WUR 모드로 되돌아가고, 상기 제2 시간 내에 상기 AP가 송신하는 상기 WUR 신호가 검출되지 않으면 PCR을 통해 상기 AP를 스캐닝 할 수 있다.
