Title:
METHOD FOR TRANSMITTING OR RECEIVING FRAME IN WIRELESS LAN SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/013459
Kind Code:
A1
Abstract:
A method by which a STA receives a WUR signal in a WLAN, according to one embodiment of the present invention, comprises the steps of: performing synchronization on a WUR PPDU on the basis of a synchronization sequence included in a WUR preamble of the WUR PPDU; acquiring information on a data rate on the basis of a signature sequence located next to the synchronization sequence in the WUR preamble; and decoding data included in the WUR PPDU on the basis of the acquired information on a data rate, wherein a plurality of candidate sequences having an inter-hamming distance greater than or equal to a threshold value, and corresponding to different data rates, are set in the STA, and, if the signature sequence matches none of the plurality of candidate sequences, the STA can correct the signature sequence to a particular candidate sequence through an error correction and decode the data by using the data rate corresponding to the particular candidate sequence.
