Description
Technical field
The present invention relates to field of communication technology, in particular to the communication means of WLAN, WLAN
Communication device and communication equipment.
Background technology
In July, 2016, IEEE (Institute of Electrical and Electronics Engineers, electricity
Gas and Electronic Engineering Association) 802.11 set up next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology
Seminar WUR (Wake Up Receiver), in terms of being mainly used in Internet of Things, in order to as much as possible save equipment
Power consumption.
In order to enable equipment more power saving, principal communication interface are at power-off in WUR (i.e. IEEE802.11ba)
(power off) state, principal communication interface refer to the interface for data communication in existing IEEE802.11 standards, and secondly logical
Believe that the interface interface of hair (WUR frames receive) is in power-up state (power on), is obtained for intercepting wake-up (wake-up) frames
The downlink data of AP (Access Point, access point) cachings is intercepted and is solved wherein for the equipment for receiving wake-up association
It is 1mW to analyse the maximum power dissipation needed for wake-up association.
And there may be following situations in certain application scenarios of IEEE802.11ba, it is for example certain battery-driven
Equipment, in order to enable equipment can more power saving, receive wake-up frames periodically carry out, i.e. the secondary communication of equipment
Interface can also be in off-position；In addition, the secondary communication interface of also some equipment is constantly in power-up state, that is, it is constantly in
Wake-up frames intercept and reception state.
Accordingly, it is considered to arrive different application scenarios so that when equipment more power saving need to send wake-up frames, with why
The frequency transmission of sample is defined, disclosure satisfy that the demand of WUR.
Invention content
The present invention is based at least one above-mentioned technical problem, it is proposed that a kind of communication party of new WLAN
