Systems and methods for low power wake-up signal implementation and operations for WLAN
First Claim
1. An apparatus for wireless communications, comprising:
- a first receiver;
a processing system configured to activate the first receiver for a period of time exceeding or equaling at least a transmission period of a wake-up sequence, wherein the wake-up sequence comprises a wake-up message and the transmission period of the wake-up sequence comprises a wake-up message transmission period, and wherein the first receiver is configured to receive the wake-up message during the period of time and to provide, in response, a signal to operate a second receiver in the apparatus; and
a transmitter configured to transmit a message acknowledging receipt of the wake-up message.

Abstract
Systems, methods, and devices for wireless communication are disclosed. In one implementation an apparatus for wireless communications is provided. The apparatus includes a receiver configured to receive a wake-up message that is a portion of a wake-up sequence. In certain implementations, the apparatus further includes a processing system operably coupled to the receiver and configured to wake the receiver for a period of time. The period of time can exceed at least a transmission period of the wake-up sequence plus a transmission period of the wake-up message. The apparatus can further include a transmitter configured to transmit a message acknowledging receipt of the wake-up message.
