METHOD FOR TRANSMITTING OR RECEIVING WAKE UP RADIO FRAME IN WIRELESS LAN SYSTEM, AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/164380

Kind Code:

A1

Abstract:

A method by which an access point (AP) transmits a wake up radio (WUR) physical layer protocol data unit (PPDU) in a wireless LAN system, according to one embodiment of the present invention, comprises the steps of: generating a WUR preamble including a sequence for time synchronization and a WUR SIG (signal) field; and transmitting a WUR PPDU including the generated WUR preamble and a WUR frame body, wherein the sequence for time synchronization repeatedly generates the minimum repetitive sequence of an N-bit length at least twice, N is an integer of 2 or more, and the first N-bit of the WUR SIG field positioned next to the sequence for time synchronization can be set to one of bit values other than the bit value corresponding to the minimum repetitive sequence among a plurality of bit values that can be expressed by an N-bit.
