Description
Technical field
It is wireless in particular to a kind of communication means of WLAN, one kind the present invention relates to communication technical field
The communicator of LAN, a kind of website and a kind of access point.
Background technology
Wi-Fi of future generation (Wireless Fidelity, Wireless Fidelity) technology has been set up in July, 2016,802.11
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 the formulation process of standard, there is manuscript to define two kinds of forms that equipment receives data：The first is to receive just
Normal packet；Second is reception wake-up (Wake up) frame.Wherein, Master Communication Equipment in a dormant state is receiving
Revival (Awake) state can be returned to after Wake up frames and carries out normal data communication, it is seen then that defines the mesh of Wake up bags
Be in order to beneficial to equipment save power consumption, wherein, principal communication refer to carry out IEEE802.11 data communication or other signalings
Communication, for example send probe request etc..
In existing Wi-Fi technology, if recipient receives the communication frame of sender's transmission, typically with reception
Transmit power and MCS (Modulation and Coding Scheme, modulation and coding strategy) mode of the communication frame arrived is come
Reply sender.And in WUR, if recipient receive after wake up frames also with the transmit power of wake up frames back and forth
Multiple sender, so can be by larger interference, and main cause is that the transmit power of wake up frames is smaller, therefore in order to avoid
This problem needs to redefine handling process of the recipient after wake up frames are received.
The content of the invention
The present invention is based at least one above-mentioned technical problem, it is proposed that a kind of communication party of new WLAN
Case, can avoid confirmation message frame use with wake up frame identical transmission powers and cause the transmission of confirmation message frame by
Larger interference.
In view of this, according to the first aspect of the invention, it is proposed that a kind of communication means of WLAN, including：Connect
When receiving wake up frames, into wake states；Confirmation message frame of the generation for the wake up frames；To the wake up
The sender of frame sends the confirmation message frame, wherein, the transmission power of the confirmation message frame is more than the wake up frames
Transmission power.
In the technical scheme, Master Communication Equipment may be at dormancy (Sleep) shape before wake up frames are received
The state of state, power saving (Power Saving) state or wake up frame definitions, in order to reduce power consumption.When receiving wake up
During frame, the confirmation message frame of wake up frames is directed to by generating and sending, and the transmission power of confirmation message frame is more than
The transmission power of wake up frames so that the confirmation message frame of device replied can be transmitted with larger transmission power, and then
Can avoid confirmation message frame use with wake up frame identical transmission powers and cause the transmission of confirmation message frame by larger
Interference.
Wherein, the transmission power of wake up frames is probably 100 microwatts (μ W), it is also possible to and it is smaller, and it is normal
The transmission power of IEEE802.11 communication frames is tens times of wake up frame transmission powers, even more greatly.
Wherein, CS (Carrier Sense, carrier sense)/CCA (the Clear Channel of wake up frames are perceived
Assessment, channel idle detection) state machine with the CS/CCA state machines for perceiving non-wake up frames can be two physics realities
Body, that is, it is physically isolated；Perceive CS/CCA state machine of the CS/CCA state machines of wake up frames with perceiving non-wake up frames
A physical entity can also be shared, but is logically separated.

Wherein, confirmation message frame can use BPSK (Binary Phase Shift Keying, binary phase shift keying) or
QPSK (Quadrature Phase Shift Keying, QPSK) modulation system, and wake up frames use OOK
(On-Off Keying, binary system on off keying) mode.
According to the second aspect of the invention, it is also proposed that a kind of communication means of WLAN, including：Generate and send
Wake up frames；After the wake up frames are sent, receive that the recipients of the wake up frames sends is directed to the wake
The confirmation message frame of up frames, wherein, the transmission power of the wake up frames is less than the transmission power of the confirmation message frame.
In the technical scheme, by making the transmission power of wake up frames be less than the transmission power of confirmation message frame so that
The transmission that can be tried one's best not to other data frames that sends of wake up frames interferes, while can also avoid confirmation message frame
Cause the transmission of confirmation message frame by larger interference using with wake up frame identical transmission powers.
Wherein, the transmission power of wake up frames is probably 100 μ W, it is also possible to and it is smaller, and normal IEEE802.11 communications
The transmission power of frame is tens times of wake up frame transmission powers, even more greatly.
In the above-mentioned technical solutions, it is preferable that include indicating bit in the wake up frames, the indicating bit be used for
The recipients of the wake up frames indicates that the confirmation message frame can be delayed transmission.
In the technical scheme, when the recipient of wake up frames is receiving wake up frames, it is possible that channel
Busy the problem of can not sending confirmation message frame immediately, therefore by setting indicating bit in wake up frames come to wake up frames
Recipient indicate that confirmation message frame can be delayed transmission so that when the recipient of wake up frames can wait channel idle again
Send confirmation message frame.
According to the third aspect of the invention we, it is also proposed that a kind of communicator of WLAN, including：Receiving unit,
