Description
Technical field
The present invention relates to technical field of communication network, communication means, one kind in particular to a kind of WLAN
The communication device of WLAN, a kind of access point apparatus and a kind of site apparatus.
Background technique
In July, 2016, IEEE (Institute of Electrical and Electronic Engineers, electricity
Gas and Electronic Engineering Association) 802.11 set up next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology
Study group WUR (Wake up Receiver), i.e. IEEE (Institute of Electrical and Electronic
Engineers, Institute of Electrical and Electronics Engineers) 802.11ba, in terms of being mainly used in Internet of Things, it is therefore an objective to as much as possible
Save the power consumption of equipment.
A kind of wakeup message (wake up) frame is defined in IEEE 802.11ba standard, main purpose is for calling out
Wake up the principal communication interface of communication equipment, i.e. communication equipment passes through time communication interface and receives wake up frame, needed for power consumption it is little
In 1mw, therefore, the stand-by power consumption of secondary communication interface is far below principal communication interface, is conducive to communication equipment and saves power consumption.
In the related technology, in order to reduce the power consumption for sending and receiving wake up frame, need to reduce the length of wake up frame,
Therefore, defining the address information that wake up frame carries is not MAC (Media Access Control, MAC sublayer
Agreement) address, in order to reduce the generation of data collision, it is still necessary to the ground of access point apparatus and site apparatus negotiation wake up frame
Still specifically how to negotiate the reception address for determining wake up frame and send address not explicitly define but in location domain.
