In the multi-user wake-up packet, a frequency channel can be divided into several sub-channels for transmitting multiple wake-up signals in FDMA. Each wake-up signal is modulated in ON/OFF Key modulation. Two adjacent wake-up signals are adequately spaced apart by a certain frequency spacing to reduce adjacent channel interferences. Once a WUR on a receive device receives the packet, it generates a wake-up indication to wake up the main radio for active data communication. The MU wake-up packet may also include a sequence of multiple wake-up signals transmitted using the same sub-channel and cascaded in a time-domain. A reconfiguration window may be inserted between consecutive wake-up signals on the same sub-channel, and between a legacy preamble and the following wakeup signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-user (MU) wake-up signal transmission by using FDMA scheme in WLAN","description":"Systems and methods of transmitting a multi-user (MU) wake-up packet in WLAN including wake-up signals to activate main radios on multiple communication devices via the wake-up radios (WURs).
