Method and apparatus for low-power scanning in WLAN system
Abstract:
The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for low-power scanning in a WLAN system. A method for a station (STA) scanning in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: transmitting a null data packet (NDP) probe request frame; and receiving from an access point (AP) a probe reply frame as a replay to the NDP probe request frame, wherein the NDP probe request frame can include a compressed service set ID (SSID).
Abstract(Chinese):

无线通信系统技术领域本发明涉及一种无线通信系统，更具体地说，本发明涉及一种WLAN系统中低功耗扫描的方法和装置。 根据本发明的一个实施例，在无线通信系统中进行站（STA）扫描的方法包括以下步骤：发送空数据分组（NDP）探测请求帧; 并且从所述接入点（AP）接收探测应答帧作为所述NDP探测请求帧的重播，其中，所述NDP探测请求帧可以包括压缩服务集ID（SSID）。
