Abstract

See full text

Embodiments described herein provide a method for transmitting a wake-up radio packet to low power devices in a wireless local area network. At a wireless access point having a plurality of antennas, data for transmission to one or more lower power wireless devices are received. A wake-up radio packet, including a wake-up data frame, is configured for transmission to the one or more lower power wireless devices. A waveform for transmitting the wake-up radio packet is generated. At each of the plurality of antennas, the waveform is adjusted with spatial mapping to prevent unintentional spatial nulling of the waveform during transmission of the wake-up radio packet. The wake-up radio packet is transmitted, via the plurality of antennas, in a form of the adjusted waveform to the one or more lower power wireless devices prior to transmitting the received data to the one or more lower power wireless devices.
