Title:
METHOD FOR TRANSMITTING AND RECEIVING WAKE-UP SIGNAL IN WIRELESS LAN SYSTEM AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/074740
Kind Code:
A1
Abstract:
A method for receiving a WUR signal by an STA, according to one embodiment of the present invention, comprises the steps of: detecting a WUR preamble sequence included in a WUR PPDU through a WUR receiver of the STA, while a WLAN receiver of the STA is turned off; obtaining WUR data included in the WUR PPDU, on the basis of a timing synchronized through the WUR preamble sequence; and outputting a wake-up signal to the WLAN receiver through the WUR receiver of the STA if the WUR data is intended for the STA, wherein the WUR preamble sequence used for the synchronization corresponds to a signature sequence carrying specific information, and the specific information may include at least one of an SU/MU indicator indicating whether the WUR PPDU is for a single user (SU) or a multi-user (MU), and information on the bandwidth of the WLAN PPDU to be received after wake-up by the WLAN receiver.
