Title:
METHOD AND DEVICE FOR TRANSMITTING WAKEUP PACKET IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/050191
Kind Code:
A1
Abstract:
Presented are a method and device for transmitting a wakeup packet in a wireless LAN system. Specifically, the transmission device configures a first wakeup packet having a first data rate by using a first sync field, and a second wakeup packet having a second data rate by using a second sync field. The transmission device transmits the first and second wakeup packets to a receiving device. Here, an OOK scheme is applied to the first and second wakeup packets to configure the first and second wakeup packets as an ON signal or an OFF signal. The first sync field includes a first sequence, and the second sync field includes a second sequence which is a complementary sequence to the first sequence. The number of coefficient 1 and coefficient 0 included in the first sequence is the same. The first and second sequences have a 32 bit length, and each bit of the first and second sequences has a duration of 2 µs.
