In the present embodiment, the first STA first wakes up the main transceiver of AP, and then the first STA sends upstream data to AP, AP can also send data transmission instruction in data interaction during this, and data transmission instruction is used to indicate the first STA's Main transceiver stays awake for.Specifically, AP continues traveling downwardly number with the first STA immediately after the reception of upstream data According to transmission.AP can be sent in the upstream data sent to the first STA receives successful acknowledgement frame by information bit The data transmission indicates, can also will confirm that frame is polymerize with other mac frames, passes through other mac frames, such as empty service High-throughput control field (the High Throughput of quality (Quality of Service Null, QoS Null) frame Control, HTC) carry out bearer data transmission instruction.When the first STA receives data transmission instruction, then the first STA is being transferred After upstream data, dormant state will not be entered, but wait the reception of downlink data.After demand has been expressed, and obtain After confirmation, AP can carry out downlink data transmission with the first STA immediately, alternatively, first competitive channel, after obtaining channel, Downlink data transmission is carried out again.Where depending on whether allow AP extension transmission opportunity (Transmit Opportunity, TXOP) or using the first STA transmission opportunity.

Except indicating demand, AP can also directly will confirm that frame needs the downlink frame sent to condense together together, to send Downlink frame, and pass through and indicate whether also more downlink frames, to indicate whether the downlink data transmission with the first STA is tied Beam.

In addition, in silence interval, if AP is waken up by the first STA, in data interaction, except immediately with the first STA Continue the transmission of downlink data, AP can also preengage with the first STA needs the MR or WUR of the first STA to open first Open section.First open section in, if AP have transmission data demand, this first open section in, with this first STA carries out the interaction of downlink data.

For the present embodiment by transmitting uplink data, AP sends reservation information to STA, with when carrying out uplink, The transmission of downlink data is preengage, reduces time delay, improves system effectiveness.

In the above-described embodiment, the notification frame sent for STAs of the AP into cell, in part, STA is opened in WUR It opens, in the case that part STA is in MR unlatchings, there is following several sending methods：

A kind of possible sending method is that AP sends WUP and wakes up all purposes STA first.Then AP is again to all STA's MR sends broadcast frame.

Alternatively possible sending method, AP send WUP and wake up purpose STA, and inform that STA prepares to receive next beacon Frame.

Another possible sending method outside AP sends notification frame to the MR of STA, can also carry notice letter by WUP Breath is sent to the WUR of STA.

On the basis of above-described embodiment, the wake-up receiver of AP can also receive the 3rd STA transmissions in silence interval 5th wake-up association, the 5th wake-up association include releasing information, and releasing information includes releasing type, releases type including as follows In any：It goes to associate, goes certification, deletes Business Stream, the confirmation of deletion block, direct link foundation releasing, mesh pairing closing.

Specifically, carry out association (disassociation) when the 3rd STA wishes same AP, go certification (deauthentication), delete Business Stream (Delete Traffic Stream, DELTS), delete block confirmation (Delete Block Acknowledgement, DELBA), direct link, which is established, releases (Direct Link Setup Teardown, DLS Teardown), mesh pairing closes (Mesh Peering Close) when operating processes, can send corresponding MAC to AP Frame.Optionally, the reason for releasing certain relation code (reason code) can also be carried.Above-mentioned a variety of mac frames are taken Unified reason code fields, some reason code are can be common by a variety of mac frames institute, such as reason When code is 1, the meaning of instruction for it is no specific the reasons why, can be used for above all of operation.Some reason code are only Can apply in certain type of mac frame, such as when reason code are 4, the reasons why instruction be because no longer loosing, It is desirable that disassociation, therefore may only apply and go in disassociation frame.

When AP in a dormant state when, some information can be carried by WUP, and AP is not required to wake up and replys acknowledgement frame etc. It informs and is successfully received, for example notice AP oneself associate, and for the information of the type, may not need at wake-up In the AP of dormancy, but relevant information is directly carried by WUP, tell AP oneself operation to be performed.

Fig. 8 is the frame format schematic diagram of wake-up association provided in an embodiment of the present invention.As shown in figure 8, using 802.11 agreements as Example illustrates.Front is optional traditional 802.11 lead codes, and 802.11 legacy preamble code includes Legacy white silk Field (Legacy Short Training Field, L-STF), traditional long training field (Legacy Long Training Field, L-LTF), legacy signaling field (Legacy Signal Field, L-SIG), for ensureing backwards compatibility so that The STA of release criteria can understand legacy preamble code part in the past.Duration information in L-SIG can cause traditional equipment to learn The lasting duration of current data packet, therefore 802.11 equipment of periphery of lead code, will not seize channel, for protecting in the duration Protecting wake-up association further part will not be disturbed by traditional 802.11 equipment.It is below WUP parts, is modulated using OOK, only WUR is It can understand.The part may include waking up lead code (Wake-up Preamble) for identifying WUP signals, MAC Header (Medium Access Control, media intervention control, it includes WUR ID, for distinguishing different WUR), frame Body (frame carrier can carry some other information), Frame Check Sequence (Frame Check Sequence, FCS), for ensuring The data received are as data during transmission.Here WUR id informations can be the complete network identities of WUR or brief net Network identifies or other can distinguish the information of different WUR.

When WUP is carried and released information, for example, it is necessary to AP associate, remove certification, DELTS, DELBA, DLS In the following manner realization may be employed when operations in teardown, Mesh Peering Close：

The type of institute's carrying information is included in WUP, type includes and goes to associate, go certification, DELTS, DELBA, DLS One or more in teardown, Mesh Peering Close, without including reason code.The benefit of which The expense that reason code are brought is the reduction of, shortcoming is that AP does not know the reason for STA carries out the generic operation.

Include the type of carrying information in WUP, and type uniformly indicates that the WUP is a kind of comprising reason code WUP.It goes to further discriminate between the operation specifically to carry out by reason code：Go to associate, go certification, DELTS, DELBA, DLS teardown、Mesh Peering Close.Current part reason code are by one or more different MAC Frame is common, it is therefore desirable to which de-fuzzy ensures that a certain kind reason code can refer in particular to some mac frame or refer in particular to a certain The specific operation of item.For example, can the reason code of no specific reason be carried out different extensions to number.Such as It when reason code are 1, are designated as no specific reason and associate, when reason code are 2, instruction is not specific Reason carries out certification, when reason code are 3, indicates that no specific reason carries out DLS teardown etc..

The frame type of MAC and reason code are included simultaneously, only include the required reason of frame type of corresponding MAC Code compresses reason code accordingly.For example, when reason code are 10, it is meant that because work( The information of rate competence element can not receive and associate.The reason is only applicable to associated mac frame, therefore should Reason code are existed only in the reason code of associated mac frame, for other kinds of mac frame, then need not The reason code, can delete it, and uniformly be compressed.

The present embodiment carries information by WUP, since the rate of WUP is relatively low, it is therefore desirable to consider to reduce expense, therefore can To be compressed in itself to reason code, situation reserved accordingly is reduced, reduces the bit of reason code.

The present embodiment need not wake up AP, only transfer data by wake-up association, reduce AP switching states and opening The power of required consuming when MR is received.
