Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is described.

The embodiment of the invention discloses a kind of dormancy control method and relevant device, can make STA Correspondent Node AP without Method sends or can not be in received situation, into dormant state, to save the power consumption of the STA.In order to better understand this Inventive embodiments are below first described the application scenarios of the embodiment of the present invention.

Referring to Fig. 1, Fig. 1 is a kind of schematic diagram of application scenarios disclosed by the embodiments of the present invention.Application shown in Fig. 1 In scene, AP1 and its transmit coverage area in and STA1, STA2 associated with it constitute a BSS, the mark of the BSS Knowing is BSS1；AP2 and its transmit coverage area in and STA associated with it constitute another BSS, the mark of the BSS For BSS2；Since there are Chong Die, composition Overlapping Basic Service Sets with the transmission coverage area of AP2 in BSS2 by AP1 in BSS1 (OBSS).Wherein, as shown in Figure 1, AP1 and STA1, STA3 are in the transmission range of AP2, therefore, AP1 and STA1, STA3 can Receive the PPDU packet of AP2 transmission.

It should be noted that AP1 and AP2 can be realized by independent physical equipment respectively, it can also be by the same physical equipment It realizes, AP1 and AP2 make logic distinguishing on same physical equipment, to form different BSS.

Under application scenarios shown in Fig. 1, referring to Fig. 2, Fig. 2 is that PPDU packet is transmitted across in OBSS disclosed in the prior art Journey schematic diagram.Wherein, the PPDU packet that AP2 is sent can be received by AP1 and STA1, and the signal energy of the PPDU packet disturbs AP1, makes AP1 can not carry out sending and receiving for information, and the communications status of AP1 is identified as busy (Buzy, or be Physical carrier sense It is busy) or it is virtual busy (Virtual Buzy, or busy for virtual carrier sensing in wireless network communication), however, STA1 and ignorant AP1 is being received simultaneously Receive interference when to the PPDU packet, thus, as shown in Fig. 2, STA1 be possible to do in the duration of the PPDU packet it is invalid It monitors, or failed transmission is done to AP1, even if sending PPDU packet to AP1, can not also receive AP1 for PPDU packet feedback Confirmation packet, i.e., be this time transmitted as failed transmission.Any of the above situation, duration of the STA1 in the PPDU packet busy channel It is interior, waste power consumption.

For application scenarios shown in FIG. 1 there are transmission process defect shown in Fig. 2, Fig. 3 and Fig. 4 are seen, wherein figure 3 be a kind of PPDU packet schematic diagram of transmission process disclosed by the embodiments of the present invention；Fig. 4 is another kind disclosed by the embodiments of the present invention PPDU packet schematic diagram of transmission process.Fig. 3 indicates to carry out downlink biography to STA1 using AP1 after method described in the embodiment of the present invention Defeated process, Fig. 4 indicate the process for carrying out uplink to AP1 using STA1 after method described in the embodiment of the present invention.AP1 With STA1 Correspondent Node each other.It can refer to dormancy control method shown in fig. 5 in conjunction with Fig. 3 and Fig. 4, STA1 to realize and AP1 progress The transmission of PPDU packet.Specifically, referring to Fig. 5, Fig. 5 is a kind of process signal of dormancy control method disclosed by the embodiments of the present invention Figure.

Whether step S501, AP1 judge the PPDU packet when receiving the PPDU packet that other access points are sent in OBSS Meet the condition interfered to Current Communications Status.

In one embodiment, AP1 can determine whether the PPDU when receiving the PPDU packet that other access points are sent in OBSS Whether packet meets the condition interfered to Current Communications Status.Specifically, when AP1 receives the PPDU packet of other AP transmission When, it can determine whether the PPDU packet meets the condition interfered to AP1 Current Communications Status.Wherein, AP1 can pass through the PPDU Physical layer preamble (PHY PREAMBLE) information of packet determines the source of the PPDU packet, and PHY preface information can carry transmission should BSS mark belonging to PPDU packet, such as SSID (Service Set Identifier, service set), BSSID (Basic Service Set Identifier, basic service set identification), the position color in BSS etc..AP1 is affiliated by the PPDU packet BSS mark can determine the PPDU packet whether from OBSS, specifically, can be by judging the mark of BSS entrained by PHY preface information Whether knowledge is identical as BSS mark belonging to AP1, if BSS mark is different from the mark of BSS belonging to AP1, shows the PPDU packet Other AP in OBSS.

As optional embodiment, judges whether the PPDU packet received meets and Current Communications Status is interfered, it can Judged by the following conditions:

(1), whether the signal strength of the PPDU packet is greater than predetermined threshold value.

Wherein, which can be determined by the communication standard in WLAN, can also be defaulted according to the reiving/transmitting state of AP1 true It is fixed.Such as it can be received or be sent according to AP1 current communications status, determine different threshold values, if working as the PPDU packet Format when meeting 802.11ax standard,, can when receiving the PPDU packet of the OBSS such as when AP1 needs to send PPDU packet Whether the signal strength for judging the PPDU packet is more than maximum space multiplexing thresholding；When AP1 needs to receive PPDU packet, when receiving When the OBSSPPDU packet, can determine whether the signal strength of the PPDU packet is more than maximum allowable interference threshold.Wherein, maximum control The size of multiplexing thresholding and maximum allowable interference threshold value may be set to identical, also may be set to difference.

If the signal strength of the PPDU packet is greater than predetermined threshold value, show that the PPDU packet can send or receive AP1 State interferes.

(2), whether the transmission frequency of the PPDU packet is greater than the default frequency.

Wherein, if frequently received whithin a period of time from the PPDU packet that the same AP is sent, it can determine whether the PPDU Whether the transmission frequency of packet is greater than the default frequency, if the frequency in the PPDU packet for receiving AP transmission is greater than the default frequency, Show that the PPDU packet interferes the state that sends or receives of AP1.

(3), the occupied channel duration of the PPDU packet is greater than preset duration.

Wherein, if the occupied channel duration of the PPDU packet influences when sending and receiving of AP1 enough, that is, the channel occupied When duration is greater than preset duration, then show that the PPDU packet interferes the state that sends or receives of AP1.

It should be noted that whether the PPDU packet that receives of judgement meets the condition interfered to Current Communications Status also It can be the combination of one or more of above-mentioned condition.As AP1 can frequently receive other in OBSS whithin a period of time When the PPDU packet of AP (such as AP2), even if the transmission frequency of PPDU packet does not reach predeterminated frequency, if the PPDU packet that AP1 is received Comparatively dense, and the short frame interval between PPDU packet is not enough to that AP1 is supported to carry out receiving or sending for other PPDU packets, then shows this The shared channel length of a little PPDU packets is greater than preset duration, equally causes interference to the communications status of AP1.

Step S502, if the result judged be it is yes, the access point identity for sending the PPDU packet is added to interference by AP1 It accesses in point set.

In one embodiment, when judging that receiving PPDU packet causes the interference to AP1 Current Communications Status, then will The mark of the source AP (such as AP2) of the PPDU packet is added in interfering AP set.Wherein, interfering AP set, which can be divided into, influences AP1 The interfering AP set of transmission, and influence the received interfering AP set of AP1.Alternatively, in interfering AP set, to each interfering AP Interference type is added, interference type may include the transmission of interfering AP 1 or the reception of interfering AP 1.

Optionally, AP1 can also set the set of other AP in interference OBSS, i.e., the PPDU that addition AP1 is sent in the set Interfered with AP mark is wrapped, if the data-signal that AP1 is sent is sufficiently strong, when causing Communication Jamming to AP2, AP1 can also be incited somebody to action The mark of AP2 is added in AP1 institute interfering AP set.

Step S503, AP1 send instruction frame to STA1, wherein the interference access point set is carried in the instruction frame.

In one embodiment, AP1 can send instruction frame to STA1, wherein carry above-mentioned AP1 in the instruction frame and built Vertical interfering AP set.Wherein, AP1 can unicast or multicast form send the instruction frame.If AP1 is sent in the form of unicast The instruction frame, then after AP1 and STA1 is associated, AP1 sends the instruction frame to STA1 in the form of unicast；If AP1 is with multicast Form send the instruction frame, then AP1 can to its association or need associated multiple STA (including STA1) to send the instruction Frame.

Wherein, which can be management frame or beacon frame, and the identification information of interference access point set can be located at instruction frame In BSSID, Multiple BSSID, BSS Color or Multiple BSS Color field in.

Step S504, STA1 are done in interference access point set after receiving the instruction frame when receiving When disturbing the PPDU packet of access point, the duration for the busy channel stated in the PPDU packet is determined.

In one embodiment, STA1 is after receiving the instruction frame, when receiving PPDU packet, it may be determined that the PPDU packet Source AP identify whether entrained by the instruction frame in interfering AP set, however, it is determined that the PPDU packet received is from interfering AP The PPDU packet of interfering AP in set, then can further determine that the duration for the busy channel stated in the PPDU packet.

Specifically, the duration for the busy channel stated in the PPDU packet can be the duration of the PPDU packet, It can be the duration for including the PPDU packet and the packet for needing to transmit after it, i.e., received PPDU packet can be stated and is somebody's turn to do A series of duration of the busy channel of packets of PPDU packet.Optionally, can according in PPDU packet TXOP field or NAV field it is true Determine duration, or the field length to be transmitted of the packet is determined according to the LENGTH field in PPDU packet, and according to rate Or the fields such as MCS determine the transmission ratio of the packet, to can determine the duration of the packet busy channel.

Step S505, STA1 determine sleep time based on the duration.

In one embodiment, when the STA1 PPDU packet received by parsing determines the occupancy letter that the PPDU packet is stated After the duration in road, the sleep time of STA1 can be determined according to the duration.Specifically, if it is determined that PPDU packet was stated The duration of busy channel is a series of transmission duration of PPDU packets, then can determine that the sleep time is less than or equal to the transmission Duration, i.e. STA1 can be dormant state in the Series P PDU packet busy channel end of transmission or before terminating；If it is determined that PPDU The duration for wrapping stated busy channel is the transmitting continuous duration of the packet, then determined by sleep time be smaller than or Equal to the transmission duration of the packet, it can also further consider that the packet needs to receive after transport the confirmation that connection object is fed back Packet, and the packet transmits and confirms that there is also short frame gaps between packet reception, are somebody's turn to do from can determine that the sleep time is less than or equal to The duration summation of the duration of the duration of packet or the duration of the packet, the duration of short frame gap and confirmation packet.

Step S506, STA1 carry out suspend mode in the sleep time, when STA1 suspend mode, stop channel sense and stop with The communication of AP1, thus it is in power save mode.

In one embodiment, after determining the sleep time of STA1, STA1 can be dormant state in the sleep time. A kind of dormant state described in the embodiment of the present invention actually power save mode (Power Save Mode) is stopped when STA1 is in When dormancy state, other than the communication between stopping and AP1 and ceasing listening for channel, it can also be achieved other function, i.e., do not influence The execution state of other function in STA1.

Optionally, STA1 is before entering dormant state, the status of action that also detectable AP1 is presently in, if the row of AP1 Dynamic state is stationary state, then shows that the AP set of interfering AP 1 is comparatively stable.I.e. in the time of interfering AP busy channel Interior, AP1 can not carry out data transmission due to being interfered, can the status of action of AP1 be stationary state when, STA1 into Enter dormant state.If the status of action of AP1 is moving condition, the combination in the AP set of interfering AP 1 is possible to becoming always Change, i.e. BSS belonging to AP1 may constitute OBSS from BSS belonging to other different AP in mobile different moments, therefore, i.e., Just some AP interferes the communication of AP1 at current time, it is possible to the disturbance range of the AP is left in subsequent time AP1, It can be carried out normal communication etc. again, therefore, if in the case that the status of action of AP1 is in moving condition, STA1, which can close to enter, to stop The function of dormancy state can also enter dormant state etc. in particular moment according to the agreement between AP1.

Optionally, when AP1 and STA1 receive the PPDU packet of interfering AP transmission simultaneously, AP1 and STA1 can be by above-mentioned Identical mode determines the duration for the busy channel that PPDU packet is stated, and AP1 can be based on identified duration It determines that interfering AP interferes it duration, and interferes in duration herein, it is busy for identifying the communications status of AP1.AP1 mark communication shape State is that busy duration can be corresponding with the sleep time of STA1.

By the above-mentioned means, stopping determined by the duration of PPDU packet in conjunction with Fig. 3 and Fig. 4 sending to interfere based on AP2 In dormancy duration, STA1 can be at dormant state, and the communications status of AP1 can be identified as busy, and be identified as busy dry of communications status Disturbing duration can be corresponding with sleep time, that is, determines that the mode of sleep time is equally applicable to determine the interference that AP1 communications status is busy Duration.As a result, within the time that other AP occupy common user communication channel, STA1 can be by opening dormant state to save power consumption.

Referring to Fig. 6, Fig. 6 is the flow diagram of another dormancy control method disclosed by the embodiments of the present invention.This hair The method of determination of determining duration and the sleep time based on determined by the duration has been described in detail in bright embodiment. Step in other dormancy control methods can be found in Fig. 5 description.As shown in fig. 6, this method specifically includes following steps.

Step S601, STA1 parse the header packet information in the PPDU packet.

In one embodiment, in the IEEE802.11 standard that WLAN is used, transmitted PPDU is transmitted between equipment Packet may include the PHY frame originating point information and PSDU (PHY Service Data Unit, physical layer in physical layer (PHY) encapsulation Service Data Unit), the data information of MAC layer is encapsulated in the PSDU, wherein PSDU includes mac frame head information and MAC number According in the embodiment of the present invention, header packet information includes PHY frame originating point information and mac frame head information in PPDU packet.In the packet of PPDU packet It may include the duration of the PPDU packet in head information, specifically, can be by judging in the applicable IEEE802.11 of the PPDU packet A specific standards, determine from the header packet information obtain the duration specific location, if PPDU packet meets 802.11ax The format of standard, the format meet 5G network requirement, then the duration can be obtained from PHY frame originating point information, such as believe from PHY frame head NAV or TXOP field is got in breath, the numerical value in NAV frame or TXOP frame represents duration.If PPDU packet meets Format other than 802.11ax standard then can obtain the duration from mac frame head information, such as obtain from mac frame head information To NAV field, the numerical value in NAV field represents duration.

Whether step S602, STA1 judge in the header packet information comprising TXOP field value.

In one embodiment, by parsing the header packet information of PPDU packet, can further judge in the header packet information whether Include TXOP field value.Wherein, a series of transmission duration of the TXOP field to indicate PPDU packets, thus by judging the packet header It whether include TXOP field value in information, it may be determined that whether interfering AP needs to transmit a series of PPDU packets.If judging, packet header is believed Comprising TXOP field value or TXOP field value it is nonzero value in breath, then step S603~S604 can be performed；If judging, packet header is believed Do not include TXOP field value in breath or TXOP field value is null value or zero, then step S605~S606 can be performed.

Step S603, if STA1 judges to be based on the TXOP comprising the TXOP field value in the header packet information Field value determines the duration for the busy channel that the PPDU packet is stated.

In one embodiment, if judging to show the PPDU Bao Zhongsheng comprising TXOP field value in the header packet information It is bright to transmit a series of PPDU packets, thus according to TXOP field value can determine the busy channel that the PPDU packet is stated it is lasting when It is long.In the embodiment of the present invention, TXOP field value can represent the duration of stated busy channel, or can be according to TXOP word Segment value calculates duration.

Optionally, or the number of this series of PPDU packet can be determined according to other fields, if the transmission of each PPDU packet Duration is identical, then the duration of interfering AP busy channel can be determined according to the duration and number of PPDU packet.

Step S604, STA1 determine that sleep time is less than or equal to the duration.

In one embodiment, interfering AP busy channel is held when determining in the header packet information comprising TXOP field value After continuous duration, it may be determined that the sleep time of STA1 is less than or equal to the duration, i.e. the sleep time of STA1 can be no more than and hold Continuous duration, STA1 can terminate in advance dormant state, and can be at war with channel preparation.

As optional embodiment, AP1 may be based on the duration and determine that mark communications status is busy duration, Specifically, it is that busy duration can be corresponding with the sleep time of STA1 that AP1, which can keep communications status, when being less than or equal to lasting It is long.During this period, AP1 can also save power consumption.It should be noted that AP1 keep communications status be hurry duration in, AP1 is not influenced and receives PPDU packet, and when receiving the PPDU packet of carrying channel release frame transmitted by interfering AP, communication can be switched State is spare time etc..

Step S605, if STA1 judges not including the TXOP field value in the header packet information, from the packet header The duration of the PPDU packet is obtained in information, or parses the packet length and packet transmission rate in the PPDU packet, really The duration of the fixed PPDU packet is equal to the ratio of the packet length and the packet transmission rate.

In one embodiment, if STA1 judges not including TXOP field value in the header packet information, that is, show interfering AP Only transmit individual PPDU packet.Specifically, the embodiment of the invention discloses any one in following manner can determine the PPDU The duration of packet.

It (1), may include that the fields such as NAV are obtained from header packet information for indicating the duration of the packet in header packet information The field values such as NAV can determine the duration of the packet, and in the embodiment of the present invention, NAV field value can represent the duration of the packet.

(2), the information such as packet length and the packet transmission rate in packet can be also parsed, specifically, can be from header packet information, such as LENGH field is obtained in PHY frame originating point information or LEGACY PREAMBLE frame, is shown the word length of the packet, can also be obtained from packet The fields such as rate or MSC, to can determine that the duration of the packet is equal to the ratio of the packet length got and report transmission rate.

Step S606 determines that sleep time is less than or equal to the duration；Or determine that sleep time is less than or equal to The duration, short frame interval duration and the interference access point is sent to the website of the interference access point communication Confirm the duration summation of the duration of packet.

It in one embodiment, can be true when STA1 determines that interfering AP busy channel only transmits received PPDU packet The sleep time for determining STA1 may be less than or equal to the duration, or the further duration for determining the practical busy channel of interfering AP Also need to continue to the short frame interval for receiving confirmation packet, and being also contemplated that between the PPDU packet and confirmation packet, to may be used also Determine that the sleep time of STA1 may be less than or equal to the duration of the PPDU packet, short frame interval (Short Inter-frame Space, SIFS) duration and PPDU packet transmission the transmitted confirmation packet to the interfering AP of targeted sites duration Duration summation.Wherein, the form for confirming packet can be ACK (Acknowledgement, confirmation) packet, BA (Block Acknowledgement, block confirmation) packet, MBA (Multi-user Block Acknowledgement, multi-user block confirmation) Packet etc..

As optional embodiment, AP1 mark communications status is that busy duration can be sent according to interfering AP accordingly PPDU packet duration, specifically, it is that busy duration can be with the sleep time pair of STA1 that AP1, which can keep communications status, It answers, is less than or equal to duration.During this period, AP1 can also save power consumption.It should be noted that AP1 is keeping communicating shape State is not influence AP1 in busy duration and receive PPDU packet, discharges frame when receiving carrying channel transmitted by interfering AP When PPDU packet, it is spare time etc. that communications status, which can be switched,.

In the embodiment of the present invention, can based on the received information entrained by PPDU it is different, more accurate determination is stopped Dormancy duration, so as to further save the power consumption of STA1.

Referring to Fig. 7, Fig. 7 is the flow diagram of another dormancy control method disclosed by the embodiments of the present invention.In conjunction with The communication transmission process of STA1 and AP1 has been described in detail in Fig. 3 and Fig. 4, Fig. 7.

Step S701, when STA1 receives the PPDU packet for carrying out in self-interference access point set to interfere access point, STA1 inspection Survey interference type of the interference access point in the interference access point set, wherein the interference type includes interfering AP 1 Transmission and interfering AP 1 reception.

In one embodiment, as shown in figure 5, when STA1 receives the instruction frame of the carrying interfering AP set of AP1 transmission Afterwards, it can receive the PPDU packet of the interfering AP in interfering AP set.When receiving the PPDU packet of interfering AP (such as AP2), judgement The AP of the interfering AP identifies whether that in interfering AP set, AP1, can be in the same of addition AP mark when constructing interfering AP set When, determine that the interference type of the AP is the transmission of interfering AP 1 or the reception of interfering AP 1.To STA1 can by the PPDU packet come The mark of the interfering AP in source, the corresponding interference type for determining the interfering AP.Wherein the transmission of interfering AP 1 can be specially to hinder AP1 Sent or postponed the transmission of AP1.

Optionally, if AP1 can also be constructed respectively, interference sends AP set and interference receives AP set, i.e., STA1 passes through determination The mark of interfering AP can determine the interference type of the interfering AP in which set.If STA1 determines the PPDU packet received Source interfering AP interference receive AP set, then can determine the interference type of the interfering AP be interfering AP 1 receive, similarly, if STA1 determines that interfering AP sends set in interference, then can determine the interference type of the interfering AP for the transmission of interfering AP 1.

It should be noted that the interference type of interfering AP is to pass through sending and receiving for interfering AP 1 for AP1 Determine the interference type of interfering AP.

Step S702, if STA1 detects that the interference type sends for the interfering AP 1, after dormant state, Communication channel between STA1 couples and AP1 is monitored.

In one embodiment, if STA1 detects that the interference type of interfering AP (such as AP2) sends for interference, can into After the sleep time for entering dormant state, further the communication channel between AP1 is monitored, has been determined whether The PPDU packet that AP1 is sent by the communication channel.

Step S703, STA1 go out the PPDU packet from the PPDU Packet analyzing and are stated after receiving the PPDU packet of AP1 Busy channel duration.

It in one embodiment, can be from the PPDU packet after STA1, which receives AP1, passes through the PPDU packet of traffic channel In parse the duration of the busy channel that the PPDU packet is stated.Specifically, AP1 can be by broadcasting to the station being associated Point set broadcast message, wherein can be by the PPDU encapsulation broadcast message, corresponding associated different Website Hostings, institute The information of broadcast is different.AP1 can broadcast the duration of wanted busy channel.Wherein, the Website Hosting of Xiang Butong transmits information Can busy channel different periods.As shown in figure 3, STA1 can be a length of when the t0 moment parses the stated busy channel of AP1 Duration between t0~t5.

Step S704, STA1 obtain the period for sending PPDU packet in the duration to affiliated Website Hosting.

In one embodiment, when being resolved to the duration for the busy channel that the PPDU packet is stated, this can be obtained The period of PPDU packet is sent in duration to Website Hosting belonging to STA1.As shown in figure 3, multiple websites may be present in BSS1 Set, AP1 can be in the durations (t0~t5) of busy channel, different targeted sites transmission in the Website Hosting of Xiang Butong Information transmits PPDU packet to Website Hosting belonging to STA1 if AP1 is within t0~t3 period, is wherein to cut in t3~t4 period It changes the Website Hosting period, AP1 can transmit PPDU packet to other Website Hostings within t4~t5 period.

Step S705, STA1 carry out suspend mode in the duration in addition to the period in the duration.

In one embodiment, after STA1, which gets AP1, sends the period of PPDU packet to affiliated Website Hosting, such as scheme Shown in 3, which is t0~t3, then STA1 can enter dormant state in the period outside the period, as STA1 can be in t3~t5 Section is dormant state, so as to further save the power consumption of STA1.

Further, in AP1 into the period of the transmission PPDU packet of Website Hosting belonging to STA1, AP1 can be to the set of sites Different website (including STA1) transmits PPDU packet in conjunction, if AP1 when other websites are transmitted into the Website Hosting, STA1 Dormant state can be entered by not receiving AP1 in the period and sending in the duration for the PPDU packet of STA1.Specifically, STA1 can Detect whether the AP1 PPDU packet to be transmitted is directed to STA1, if the targeted sites of the PPDU packet are not STA1, STA1 can be for not Dormancy state.As shown in figure 3, STA1 receives the PPDU packet that AP1 is transmitted in t1~t2 period, then within t0~t3 period, remove T1~t2 period, STA1 dormant state not yet, so as to further save the power consumption of STA1.

It should be noted that the embodiment of the present invention essentially describes communication after STA1 terminates dormant state, with AP1 Journey.Certainly, step S703~step S705 applies also for AP1 into other scenes of STA1 progress downlink transfer, and not only After being limited to STA1 dormant state.

Step S706, if STA1 detects that the interference type receives for the interfering AP 1, after dormant state, Judge whether the sleep time is less than the duration.

In one embodiment, if STA1 detects that the interference type for the reception of interfering AP 1, can terminate in dormant state Afterwards, further judge the sleep time whether be less than determined by interfering AP the busy channel stated of PPDU packet it is lasting when It is long.If judging, the sleep time is less than duration, as shown in figure 4, STA1 terminates dormant state at the t1 moment, and AP2 is accounted for It will be terminated at the t2 moment with the duration of channel.

Step S707, if STA1 judges that the sleep time is less than the duration, when the duration When expiring, the backoff procedure for the communication channel between the target access is opened or restored.

In one embodiment, if STA1 detects that the interference type of interfering AP is that interfering AP 1 receives, if locating for STA1 The sleep time of dormant state be equal to duration, STA1 dormant state sleep time expire after, can competitive channel, with right AP1 transmits data.If judging, sleep time is less than duration, as shown in figure 4, needing after reaching duration, i.e., STA1 needs after reaching the t2 moment, can open or reply backoff procedure.To ensure that STA1 is competing to the justice of channel It strives.

Specifically, CSMA (Carrier Sense Multiple Access, Carrier Sense Multiple Access) can be used in STA1 Mechanism competes common user communication channel.Wherein, channel (needs to carry out uplink biography according to the communication ends of competition in the embodiment of the present invention Defeated website) attribute, for each website distribution keep out of the way countings, wherein this keep out of the way counting can be random value, if website detects When the free timeslot of channel, then it can will keep out of the way counting and subtract one, and when website is when keeping out of the way counting and reducing to 0, then show that the website will be striven for Communication channel is arrived.

It should be noted that STA1 can start competitive channel after dormant state, dormant state can also entered Before, be at war with the backoff procedure of channel.When receiving 1 received PPDU packet of interfering AP, it can temporarily cease and keep out of the way Process, STA1 enter dormant state, backoff procedure after dormant state terminates, before can restoring.

Step S708 passes through the traffic channel PPDU packet to AP1 after STA1 completes the backoff procedure.

In one embodiment, after STA1 completes backoff procedure, i.e. when keeping out of the way counting and being reduced to 0 of STA1, show STA1 has won channel, can pass through the channel transmission data to AP1.Specifically, reference can be made to Fig. 4, when STA1 is sent to AP1 When PPDU packet, AP1 can be properly received.

, can be after the PPDU packet end of transmission of interfering AP in the embodiment of the present invention, AP1 is communicated with STA1, sufficiently benefit With common user communication channel resource.

Referring to Fig. 8, Fig. 8 is another PPDU packet transmission process disclosed by the embodiments of the present invention.As shown in figure 8, Fig. 8 is retouched It has stated AP1 and interfering AP (AP2) shares same physical equipment, i.e., when only logically distinguishing AP1 and AP2, the biography of AP1 and STA1 Defeated process.In this transmission process, Fig. 5~dormancy control method shown in Fig. 7 is equally applicable to Fig. 8.It wouldn't repeat herein.It needs It is noted that AP1 is into the access point set of interference entrained by the instruction frame that STA1 is sent out, it may include the mutual exclusion access point of AP1 Set, i.e., application scenarios as shown in Figure 8, wherein AP2 is the mutual exclusion access point that mutual exclusion accesses in point set, target Access point and mutual exclusion access point are total to physical equipment.
