Title:
METHOD AND DEVICE FOR TRANSMITTING WAKE UP PACKET IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/190221
Kind Code:
A1
Abstract:
A method and a device for transmitting a wake up packet to a wireless LAN system are presented. Particularly, a transmission device generates a wake up packet by the application of an OOK method. The transmission device transmits the wake up packet to a reception device through a wideband. The wake up packet includes a first PPDU and a second PPDU. The first PPDU includes a first sink field and a first payload field having a first data rate. The second PPDU includes at least one cascade PPDU and a padding field. The at least one cascade PPDU includes a second sink field and a second payload field having a second data rate. The at least one cascade PPDU is a PPDU, which is continuously transmitted such that the length of the second PPDU matches the length of the first PPDU.
