Abstract

This application provides a wake-up method and device. The method includes: receiving, by a wake-up radio, a first wake-up frame, where the first wake-up frame includes a duration field, and the duration field is used to carry duration information; and waking up, by the wake-up radio, a primary radio based on the duration information. Because a wake-up frame transmitted by an access point includes duration information, a wake-up radio of a station wakes up a primary radio based on the duration information, so that the station can save energy better.
