Embodiment Construction

[0153] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0154] The wake-up method in the embodiment of the present invention can be applied to a wireless local area network (Wireless Local Area Network, referred to as "WLAN"), and can also be applied to other various communication systems, such as: Global System of Mobile Communication (Global System of Mobile Communication, referred to as "GSM") ") system, code division multiple access (Code Division Multiple Access, referred to as "CDMA") system, wideband code...

Abstract

The invention provides a wake-up method and equipment. The method includes the following steps: a wake-up transceiver receives a first wake-up frame, wherein the first wake-up frame includes a duration field, and the duration field is used to carry duration information; and the wake-up transceiver wakes up a main transceiver according to the duration information. Since the wake-up frame sent by anaccess point includes the duration information, the wake-up transceiver in a site wakes up the main transceiver according to the duration information, and the site can save energy more efficiently.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless local area networks, and more specifically, to a wake-up method and device. Background technique [0002] In a communication scenario represented by the Internet of Things ("IoT" for short), stations are usually powered by batteries, which have very high requirements for low energy consumption. Energy consumption can be greatly reduced through the sleep mechanism, and the longer the sleep cycle, the better the energy saving effect. However, an excessively long sleep cycle will lead to an increase in transmission delay. [0003] In order to solve the above problems, a Wakeup Radio (WUR for short) is usually added to the station. The WUR has two operating modes: normally open and periodically open. In the normally open operating mode, the WUR is always open, or when the main link is closed, the WUR is always open. The normally open operating mode has a simple operating mechanism and d...
