Embodiment

Below in conjunction with attached drawing, the technical solution in the embodiment of the present application is described.

Fig. 1 a and Fig. 1 b are the signals using a kind of two kinds of application scenarios of the method and apparatus of wireless communication of the application Figure.In wireless communications, in order to avoid multiple wireless devices, simultaneous transmission data cause conflict on a wireless channel, wirelessly Equipment before transmitting data, intercepts wireless channel, if the wireless channel is idle, sets back off timer, described to move back The initial value for keeping away timer determines that initial range is generally 0~7 (if sending the upper of this scope that fail at random within the specific limits Limit value can become larger).When back off timer is decremented to 0 according to regular hour unit, the wireless device sends data.Moving back During keeping away, the wireless device continues to intercept channel, if the recipient of the message/frame listened to is not described wirelessly to set Standby, then the wireless device pause is kept out of the way, and sets network allocation vector timer NAV timers (Network Allocation Vector, abbreviation NAV), the initial value of NAV timers is that duration Duration field indicates in listened to message Time.If NAV timers are configured, the wireless device listens to the report that a recipient is not the wireless device again Text/frame, and remaining time of the time of Duration therein instructions more than the NAV set, the wireless device determine NAV When device remaining time be updated to time of the Duration instructions in message/frame for listening to.If message/the frame listened to In time of Duration instructions be less than or equal to the remaining time of NAV timers set, then need not update NAV and determine When device remaining time.

During NAV runs, the wireless device can temporary transient dormancy, channel is no longer intercepted, so as to power saving.When NAV timers terminate after counting down to 0, recover back off timer and continue to count.Network allocation vector timer NAV timers are determined When process be referred to as virtual carrier sensing in wireless network communication, the wireless device thinks channel busy at this time, but actually it may not detectd Listen channel, or even in intercepting and find that channel is idle, but because may have another wireless device of a distant place just Being transmitted to oneself another wireless device more nearby, the wireless device can't hear the signal of that remote device transmission, because And during NAV timer timings, the wireless device still will regard channel busy.But if the wireless device is because receiving NAV timers, because the transmission of RTS frames may fail, the i.e. reception of RTS frames are provided with to a request to send frame RTS frame End does not send clearly transmittable frame CTS frames because the reason such as interference does not receive this RTS frame, then the wireless device can continue Channel a little while is intercepted, if not hearing that the equipment for sending RTS sends subsequent frame before the deadline, is considered as that The bust this of RTS frames, the wireless device just cancel the NAV set by because of RTS frames, recover backoff procedure.It is if described The offhand transmission message of wireless device, but waiting other wireless devices to be received may to issue the message of oneself, then hear One be not destined to oneself wireless information when, still will according in message Duration information set NAV timers, If NAV timer counts, to having message to send in 0 time, should regard channel cannot start backoff procedure (this to be busy Call a timeout backoff procedure), until NAV timer counts to 0 and to intercept channel to find channel be really the free time, can just start and move back Circumvent journey.

Basic Service Set (Basic Service Set, abbreviation BSS) refers to the WLAN of one group of wireless device composition Network, generally comprises the wireless terminal device STA that an access point AP is associated with the access point with one or more, wherein, access point Pass through wireless connection between website.In the communication system, belonging between the wireless device of a Basic Service Set can be mutual Communicate, do not allow the wireless device between different services sets directly to communicate.When the wireless device is in backoff procedure Listen to a message/frame, judge that the message/frame is the message/frame of this Basic Service Set, or overlapped coverage other Message/frame of Basic Service Set (Overlapping Basic Service Set, abbreviation OBSS).If message/the frame is The message of BSS1 Basic Service Sets and the wireless device are not the recipients of message, then need to set NAV timers；If the report Text/frame is the message of BSS2, i.e., the message/frame is message/frame of OBSS, then is made not according to the reception power for the message heard With processing.If received OBSS message sinks power is more than the SR threshold values specified, need to set NAV timers, if receiving work( Rate is less than the SR threshold values specified, and backoff procedure realizes the transmitting data in parallel on the wireless channel, i.e. space without pause Multiplexing, improves frequency spectrum service efficiency.

As shown in Figure 1a, two Basic Service Set BSS, Basic Service Set BSS1 include access point under network deployment AP1 (Access Point, abbreviation AP) and it is associated with the site STA 1 (Station, abbreviation STA) of access point AP1, website STA2；Basic Service Set BSS2 includes access point AP2 and is associated with site STA 3, the site STA 4 of access point AP2.In BSS2 Site STA 3 needs, in wireless channel f1 transmitting datas, first to intercept the wireless channel f1, when the site STA 3 is being moved back A message/frame is listened to during keeping away, it is message/frame of BSS1 to judge the message/frame, then according to the message/frame heard Reception power make different disposal.If the reception power of message/frame of received OBSS is more than the SR threshold values specified, need to set NAV timers are put, if receiving power is less than the SR threshold values specified, backoff procedure is realized in the wireless channel without pause Upper transmitting data in parallel, i.e. spatial reuse.

As shown in Figure 1 b, Basic Service Set BSS3 includes access point AP3 and is associated with the site STA 5 of access point AP3, stands Point STA6 and website 7.Site STA 6 in BSS3 needs, in wireless channel f2 transmitting datas, first to intercept the wireless channel F2, when the site STA 6 listens to a message/frame in backoff procedure, it is message/frame of BSS3 to judge the message/frame, Message/the frame listened to is the message/frame of this services set, therefore STA3 pauses are kept out of the way, and start NAV timers.

Fig. 2 is the indicative flowchart according to a kind of method 200 of wireless communication of the embodiment of the present application.Such as Fig. 2 institutes Show, this method 200 includes herein below.

210, wireless device obtains the control frame transmitted on wireless channel, and the recipient of the control frame is not described wireless Equipment, the wireless device belong to the first Basic Service Set.

The head of control frame includes the media access control address MAC Address of sender and the MAC Address of recipient.Generally Control frame in also include basic service set identification (basic service set identity, abbreviation BSSID).BSSID is The mark of one WiFi network, is the MAC Address of access point AP in this WiFi network.For example, generally from STA to AP, from AP It is the address of receiving terminal and transmitting terminal respectively to first address of the control frame of STA and second address, the 3rd address is BSSID, wherein the first address or the second address and the 3rd address are probably identical, i.e., all it is BSSID.In direct-connected control frame First address and the second address are the address of receiving terminal STA and transmitting terminal STA respectively, but the 3rd address is BSSID.In addition control Frame head also has the transmission direction of two bit instruction frames, including STA to AP, AP to STA, AP to AP, STA to STA.With reference to control Transmission direction instruction and control frame type in frame head, the wireless device, which is known that in control frame head, several MAC Address And whether include BSSID.If control frame head includes BSSID, the wireless device may determine that listened to control Frame is the first Basic Service Set frame or OBSS frames.But in all control frames, indicate two ratios of the transmission direction of frame Ad hoc is fixed " 00 ", it is impossible to from its transmission direction of the two bit decisions.At the same time control frame in order to it is short and small in favor of improve System effectiveness, only may then not include BSSID in frame head comprising two even MAC Address.Such as a STA gives its The STA of direct-connected opposite end sends request to send frame RTS frames and represents to send data, then the first address of the control frame is opposite end The address of STA, that is, receiving terminal, the second address are the address of oneself i.e. transmitting terminal, and without BSSID, therefore the side of intercepting can not just judge This is the direct-connected message or OBSS message of first Basic Service Set.And the response message as RTS message can clearly be sent out As soon as sending frame CTS frames and as the acknowledgement frame ACK frames for being properly received a data frame or management frame, wherein an only address, If CTS or ACK that AP is sent in response to STA, wherein unique address is the address of STA, the wireless device is more difficult to Identify whether the control frame belongs to the first Basic Service Set.

Alternatively, when the recipient of the control frame is the wireless device, then the wireless device receives the control Frame.

Alternatively, the control frame is request to send frame, and the request to send frame is with including receiving method, medium access control Location and sender's media access control address.

220, after the control frame is received on the wireless channel, the wireless device is received on the wireless channel Communication message physical header, the physical header includes the short identifier of Basic Service Set belonging to the communication message and described The transmission direction designator of communication message；The control frame and the communication message are from same equipment.

The control frame, the media that the wireless device includes according to the control frame are received on the wireless channel Accessing to control address, identifies whether the control frame belongs to first Basic Service Set.The matchmaker included according to the control frame Body accessing to control address, identifies whether the control frame belongs to first Basic Service Set and include：According to the control frame bag The recipient address and/or sender address included, identify the control frame whether be the first Basic Service Set access point matchmaker Body accessing to control address MAC Address；When the control frame is not the media access control of the access point of the first Basic Service Set Location, judges whether the control frame belongs to the first Basic Service Set according to the first address properties table, if first address belongs to Property table do not include the recipient address included and/or sender address of the control frame, judged according to the second address properties table Whether the control frame belongs to the services set beyond the first Basic Service Set, wherein, the first address properties table includes multiple Belong to the media access control address of the first Basic Service Set, the second address properties table includes that multiple to be not belonging to first basic The media access control address of services set.

Specifically, if the recipient address is the media access control address of the access point of the first Basic Service Set MAC Address, illustrates that the control frame is sent to the first Basic Service Set by the wireless device in first Basic Service Set Access point, the control frame belong to the first Basic Service Set, i.e., described control frame is BSS frames；If described sender address is The media access control address of the access point of first Basic Service Set, illustrates the control frame by first Basic Service Set Access point be sent to the wireless device of the first Basic Service Set, the control frame belongs to the first Basic Service Set, i.e., described control Frame processed is BSS frames.If the recipient address and sender address are not the media of the access point of the first Basic Service Set Accessing to control address, then inquire about the first address properties table to judge whether the control frame belongs to the first Basic Service Set, if Any address in recipient address or sender address belongs to the first address properties table, then it is basic to belong to first for the control frame Services set, i.e., described control frame are BSS frames.If recipient address and sender address are not belonging to first basic service Collection, then inquire about the second address properties table, if any address in reciever address or sender address belongs to the second address category Property table, then the control frame belong to the services set beyond the first Basic Service Set, i.e., described control frame is OBSS frames.

Alternatively, the media access control of the access point of the first address properties table including the first Basic Service Set Location, the media access control address included according to the control frame identify whether the control frame belongs to the described first basic clothes Business collection includes：Judge whether the control frame belongs to the first Basic Service Set according to the first address properties table, if described first Address properties table does not include the recipient address included and/or sender address of the control frame, according to the second address properties Table judges the services set whether control frame belongs to beyond the first Basic Service Set, wherein, the first address properties table bag Include the media interviews of the access point of the multiple media access control address for belonging to the first Basic Service Set and the first Basic Service Set Address/MAC address is controlled, the second address properties table includes multiple media access controls for being not belonging to the first Basic Service Set Address.

Alternatively, the first address properties table and the second address properties table can be in same address properties tables On, i.e., described address attribute list not only includes the MAC Address for belonging to the first address Basic Service Set, but also including being not belonging to the first address The MAC Address of Basic Service Set.

Alternatively, each MAC Address in the media access control address MAC Address BSS attribute lists should set one A ageing time, if it exceeds the ageing time does not hear such MAC Address again, is then deleted from MAC Address BSS attribute lists Except this MAC Address.

The wireless device can judge the control frame when receiving a control frame according to described address attribute list Basic Service Set BSS attributes, the control frame that can identify a BSSID without the first Basic Service Set is the first Basic Service Set Direct-connected frame or OBSS frame, can be easier to identify the control frame of OBSS, improve the chance of spatial reuse, improve system channel effect Rate.

Alternatively, when the transmission address of the control frame belongs to the first address properties table, the transmission of the control frame When address is not belonging to the first address properties table, the reception address of the control frame is added to the first address properties table； Or when the reception address of the control frame belongs to the first address properties table, the transmission address of the control frame is not belonging to described During the first address properties table, the transmission address of the control frame is added to the first address properties table.

In general, an equipment estimated period for needing busy channel before message transmission, with the message of transmission Duration Duration field indicates the time of busy channel, but may terminate to transmit in advance during actual transmissions, then sends knot Beam is exempted from competition frame CF-End frame notice miscellaneous equipment channels and has been released.Equipment is listening to disappearing in a BSS in order to prevent Breath is provided with after NAV timers by CF-End (Contention Free-End, end exempt to compete) frame end of an OBSS NAV timers, or equipment listen to an OBSS message be provided with NAV timers after by the CF-End of a BSS (Contention Free-End, end exempt to compete) frame end NAV timers, so as to cause the mistake of SR to perform. The IEEE802.11ax modular systems of formulation define two kinds of network allocation vector timer NAV timers, and one is conventional NAV (regular NAV, abbreviation rNAV), the other is NAV (intra BSS NAV, abbreviation iNAV) in Basic Service Set BSS.One When a equipment listens to the WiFi for not being destined to oneself message, if can recognize that this message is the first basic service The message of collection, then set iNAV timers, otherwise, just sets rNAV timers.When two NAV timers all count down to 0 Time is just considered as NAV timers and terminates, and otherwise any one NAV timer all represents channel busy when counting.Even if in fact make With two NAV timers, it would still be possible to the shape there are error ending NAV timers or before it can recover NAV timers to renewal But the state before renewal NAV timers cannot be returned to when state.Do not limited when if NAV timers are realized inside equipment The number of NAV timers, can be often to hear that one is not all to start a NAV timer to the message of oneself, as all NAV Timer just thinks that NAV timers in logic terminate when all returning 0 no longer to count, as long as otherwise there is any one NAV timer It is considered as what channel still did counting, virtual carrier sensing in wireless network communication can be better achieved by so doing.But it is constrained to realize Complexity, requires nothing more than and realizes two NAV timers.

Alternatively, when the media access control address that the control frame includes belongs to the first address properties table, root Second timer is set according to the duration Duration in the control frame, the timer is determined for internal network allocation vector When device iNAV timers, for indicating to belong to described first in the range of the second timer duration on the wireless channel having The signal transmission of Basic Service Set.

Alternatively, when the media access control address that the control frame includes is not belonging to the first address properties table, Comparing the relation for receiving power and first threshold of the control frame, the first threshold is the critical value of spatial reuse, if The reception power of control frame is greater than or equal to the first threshold, then can not achieve spatial reuse；If the reception work(of control frame Rate is less than the first threshold, then can realize spatial reuse.When the reception power of the control frame is greater than or equal to first threshold When, the duration Duration in the control frame sets first timer, and the first timer is general networks Allocation vector timer rNAV timers, for indicating having not on the wireless channel in the range of the first timer duration Belong to the signal transmission of first Basic Service Set, at this time, not can determine that the basic service set attribute of the control frame, but It is because the reception power of the Basic Service Set is more than first threshold, it is impossible to realize spatial reuse, therefore without in the case where carrying out Judgement of one step on communication message physical header, wireless device continue frame and listen channel at the appointed time, if when defined The interior equipment for not listening to transmission RTS sends subsequent frame, then is considered as the bust this of that RTS frame, described wirelessly to set The standby NAV just cancelled set by because of RTS frames, recovers backoff procedure, if listening to the equipment for sending RTS before the deadline Subsequent frame is sent, without carrying out the judgement on communication message physical header in next step.When the reception power of the control frame is small When first threshold, whether the media access control address that determining the control frame includes belongs to the second address properties table, If the control frame belongs to the second address properties table, i.e., described control frame belongs to OBSS frames, then the wireless device is described Continue backoff procedure on wireless channel.If the control frame is not belonging to the second address properties table, according in the control frame Duration Duration sets first timer.At this time, the basic service set attribute of the control frame is not can determine that, simply It is OBSS frames temporarily to think the control frame, need to be judged again according to follow-up information.

Alternatively, the spatial reuse, which refers to the wireless device, can ignore the control frame, i.e., as not listening to In the control frame, or period duration Duration that can be indicated in the control frame of the wireless device simultaneously Row transmission data.

For example, hearing a WiFi message when a wireless device is listened in backoff procedure in backoff procedure, sentence Breaking, it is the message of the first Basic Service Set or the message of OBSS, if the first Basic Service Set message and oneself not disappearing The recipient of breath, then need to set iNAV timers, it is meant that pause is kept out of the way；If the message of OBSS, then listened according to institute's frame To the reception power of message make different disposal.It is (i.e. empty that if received OBSS message sinks power is more than the first threshold specified Between multiplexing thresholds, such as -62dBm, receiving power just can be with spatial reuse less than this value), then need setting rNAV timers, If receiving power is less than the first threshold specified, ignore this message completely, as not hearing, i.e., backoff procedure need not Pause.

Alternatively, when the media access control address that the control frame includes is not belonging to the first address properties table, The second address properties table is inquired about, the second address properties table includes multiple media for being not belonging to first Basic Service Set and visits Ask control address, when the media access control address that the control frame includes belongs to the second address properties table, compare institute The relation for receiving power and first threshold of control frame is stated, when the reception power of the control frame is greater than or equal to first threshold When, the duration Duration in the control frame sets first timer, when the reception power of the control frame is small , can be with spatial reuse when the first threshold；When the media access control address that the control frame includes is not belonging to described During double-address attribute list, the relation for receiving power and first threshold of the control frame, when the reception work(of the control frame When rate is greater than or equal to first threshold, the duration Duration in the control frame sets first timer, described Second timer is general networks allocation vector timer rNAV, and the first timer is used to indicate have on the wireless channel The signal transmission of first Basic Service Set is not belonging to, when the reception power of the control frame is less than the first threshold, Duration Duration in the control frame sets the first timer, at this time, not can determine that the control The basic service set attribute of frame, it is OBSS frames simply temporarily to think the control frame, need to be sentenced again according to follow-up information It is disconnected.

The wireless device is provided with after NAV timers because receiving a request to send frame RTS frame, in order to avoid The receiving terminal of RTS frames does not send clearly transmittable frame CTS frames because the reason such as interference does not receive this RTS frame, causes information to pass Defeated failure, then the wireless device can continue to intercept channel at the appointed time.If phase is not heard at the appointed time The clearly transmittable CTS frames answered, but listen to what the wireless device was sent within the stipulated time after listening to the RTS frames Subsequent transmission frame, illustrates that the RTS frames are sent successfully, then the set first timer retains.If listening to State control frame exceed schedule time in do not hear that the wireless device for sending the control frame sends subsequent transmission frame, illustrate the control Frame processed sends failure, then the wireless device recovers the initial value of the first timer.If after the stipulated time, listen to The corresponding communication message physical header of the control frame, the physical header include the short knowledge of Basic Service Set belonging to the communication message Fu not be with the transmission direction designator of the communication message.The information then included according to the communication message physics, described in identification Whether communication message belongs to the communication message of first Basic Service Set.

Alternatively, 2 times of transmission times with allowing transmission frame CTS that the stipulated time is short interFrameGap time SISF The sum of.

Alternatively, the corresponding communication message physical header of the control frame refer to the reception power of the control frame with it is described The reception power of communication message physical header is of substantially equal.

230, when the media access control address that the wireless device includes according to the control frame can not judge the control When whether frame processed belongs to the control frame of first Basic Service Set, and belonging to the communication message that includes of the physical header Basic Service Set short identifier it is identical with the short identifier of first Basic Service Set, and according to the transmission direction Designator determines the transmission direction of the communication message when being upstream or downstream, and the wireless device determines the control frame and institute State communication message and be not belonging to first Basic Service Set, and the control frame and the Basic Service Set belonging to the communication message The short identifier of short identifier and first Basic Service Set exist and conflict.

The media access control address included when the wireless device according to the control frame does not include described first The MAC Address of the AP of Basic Service Set, and the first address properties table and the second address properties table also do not include institute The media access control address that control frame includes is stated, therefore can not judge whether the control frame belongs to first basic service The control frame of collection.At this time, the control frame may belong to the control frame of the first Basic Service Set, i.e., described control frame is the first base The direct-connected frame or the control frame of this services set are not belonging to first Basic Service Set.

Alternatively, the short identifier (BSS of the Basic Service Set according to belonging to the physical header that the communication message includes Color), identify whether the Basic Service Set of the communication message belongs to first Basic Service Set.The Basic Service Set Short identifier equivalent to the short mark of a Basic Service Set, specified by access point AP.Therefore it is likely to occur different basic The short identifier of the Basic Service Set of services set is the same, i.e. the phenomenon of the short identifier BSS Color conflicts of Basic Service Set.When The short identifier of Basic Service Set belonging to the communication message physical header and the short knowledge of the Basic Service Set of the wireless device When Fu not differ, determine that the communication message physical header is not belonging to first Basic Service Set.

Alternatively, the short identifier when the Basic Service Set belonging to the communication message physical header and the wireless device When the short identifier of Basic Service Set is identical, the transmission direction designator that is included according to the communication message physical header, knows Whether not described communication message belongs to first Basic Service Set.It can determined described according to the transmission direction designator When the transmission direction of communication message is upstream or downstream, determine that the communication message physical header is not belonging to the first Basic Service Set, I.e. described communication message physical header is OBSS frames.

Specifically, the data transfer direction designator described in the communication message physical header is a bit, works as institute State data transfer direction to be when when downlink and the transmission direction are direct-connected being same mark, it is impossible to according to the data transfer Direction instruction accords with, and the transmission direction for determining the communication message physical header is downlink；Or when the data transfer direction is uplink With the transmission direction for it is direct-connected when be same mark, it is impossible to according to the data transfer direction designator, determine described logical The transmission direction for believing message physical header is uplink.

Specifically, the transmission of the communication message physical header can determined according to the data transfer direction designator When direction is upstream or downstream, according to judging result above, the communication message physical header, which corresponds to control frame, does not include first The MAC Address of the access point AP of Basic Service Set, illustrates that the control frame may belong to first Basic Service Set, is institute State the direct-connected frame of the first Basic Service Set or be not belonging to first Basic Service Set, if the biography of the communication message physical header Defeated direction is upstream or downstream, then it is not the communication message of first Basic Service Set to illustrate the communication message physical header, So described communication message physical header is not belonging to the first Basic Service Set, i.e., described communication message physical header is OBSS messages.

In the embodiment of the present application, when cannot identify the control according to media access control address that the control frame includes When whether frame processed belongs to the control frame of first Basic Service Set, and belonging to the communication message that includes of the physical header The short identifier of Basic Service Set it is identical with the short identifier of the first Basic Service Set, and according to the transmission direction indicate When the transmission direction of the definite communication message of symbol is upstream or downstream, it is basic to determine that the communication message is not belonging to described first The communication message of services set, then can not have to parse the content behind physical header again, improve the chance of spatial reuse, in order to The wireless device power saving.

Alternatively, when indicating to determine that the communication message is not belonging to the first Basic Service Set according to the transmission direction, The then Basic Service Set short identifier BSS Color conflicts, i.e. the short identifier BSS Color of the first Basic Service Set with it is another A short identifier BSS Color of Basic Service Set are identical, it should change the short identifier BSS Color of the first Basic Service Set.When When the wireless device is the access point of first Basic Service Set, the wireless device changes the first Basic Service Set BSS Color；When the wireless device for site STA in the first Basic Service Set when, the wireless device is to the first basic service The access point AP of collection sends the first configured information, and first configured information is used to indicate that described access point AP modifications first are basic Services set BSS Color.

In the prior art, a wireless device hears that the communication message physical header with identical BSS Color is recognized first To be the first Basic Service Set message, PSDU is further parsed, obtains the mac frame of the data frame or management frame in the PSDU Head, identifies whether the communication message belongs to the first Basic Service Set according to the BSSID of the mac frame head.But to obtain It is necessary to which whole mac frame is parsed, the chance of the possible transmitting data in parallel of the mac frame for losing and intercepting, reduces mac frame head The probability of spatial reuse.The embodiment of the present application, the message included according to the communication message physical header listened to and described logical The message of the corresponding control frame listened to, identifies the presence of BSS Color conflicts before letter message physical header, so as to BSS Color can be changed in AP, improve the chance of spatial reuse, improve system channel efficiency, without parsing physical layer clothes again Content in data cell of being engaged in PSDU is in favor of the wireless device power saving.

Alternatively, when the definite communication message belongs to the communication message of the first Basic Service Set, belong to the first address Property table add the media access control address that the control frame includes, the first address properties table includes belonging to first base Multiple media access control address of this services set；Or when the definite communication message physical header is not belonging to the first Basic Service Set When, the media access control address that the control frame includes is added to the second address properties table, it is described to state the second address properties table Multiple media access control address including being not belonging to first Basic Service Set.

Alternatively, when the definite communication message belongs to the communication message of the first Basic Service Set, described first is recovered Timer, the duration Duration in communication message physical header set second timer, and the second timer is INAV timers, the second timer are used to indicate there is the signal for belonging to the first Basic Service Set biography on the wireless channel It is defeated.

Specifically, recovering the first timer has following several situations, if before setting the first timer The first timer is not actuated, i.e., the initial value of described first timer is 0, then recovers the count value of the 3rd timer For 0, that is, terminate the 3rd timer；If foregoing description first timer has been set, but count value is less than the control frame In duration Duration value and be updated, then the first timer value is reverted into the initial of the first timer It is worth to return to the value of the first timer by the count value before the Duration renewals in the control frame, i.e., described the The numerical value of one timer, which subtracts, performs the time that above-mentioned steps are consumed；If foregoing description first timer has been turned on, but counts Numerical value is more than the Duration values in the control frame, then the above-mentioned described setting first timer does not have actually Actual effect, i.e., without the first timer count value is updated, then here the first timer value is reverted to it is described The initial value of 3rd timer does not do any practical operation yet.During specific implementation, the first timer may be by hard Part realizes that therefore, it is difficult to record the state before the first timer updates every time, then once the first timer is updated Afterwards, it is impossible to the state before returning to, or simply terminate the first timer.A kind of implementation of use is, When the second address properties table does not include the media control access address of the control frame, when the first timer is set, Whether the counter according to setting foregoing description first timer is 0 record, one state, if it is determined that the communication message is not Belong to the communication message of the first Basic Service Set, and the status display of the first timer before is 0, then described in termination First timer, if the status display that the first timer before is not is 0, maintains the first timer, no Make any change.

If the state before can the first timer be returned to, according to the communication message thing being currently received The Duration managed in head sets the second timer, does not otherwise have to set the second timer.

Alternatively, when the definite communication message is not belonging to the communication message of the first Basic Service Set, to described second Address properties table adds the media access control address that the control frame includes, and the second address properties table includes being not belonging to institute State multiple media access control address of the first Basic Service Set.

Alternatively, when the definite communication message is not belonging to the communication message of the first Basic Service Set, described the is recovered One timer, it is possible to implement spatial reuse.If the value of the first timer after recovering not is 0, spatial reuse cannot perform. But wireless device, which have ignored one, receives OBSS frame of the power less than SR threshold values, and first timer is not arranged to more For a long time, this is also in spatial reuse.

Therefore, according to the embodiment of the present application, equipment is when receiving a control frame, because can be sentenced according to address attribute list Break the basic service set attribute of the control frame, can identify a media access control address without first Basic Service Set The basic service set attribute of control frame, can be easier the control frame that identification is not belonging to the first Basic Service Set；When cannot according to institute The media access control address that stating control frame includes identifies whether the control frame belongs to the control of first Basic Service Set During frame, and the short identifier of Basic Service Set belonging to the communication message that includes of the physical header and the described first basic clothes Business collects that short identifier is identical, and according to the transmission direction designator determine the transmission direction of the communication message for uplink or During downlink, determine that the communication message is not belonging to the communication message of first Basic Service Set, without parsing physics each time Layer service data unit identifies the basic service set attribute of the communication message, saves electricity；And it can also determine base The presence of this service set conflict, in order to which access point changes basic service set identification, improves the chance of spatial reuse, improves System channel service efficiency.

Fig. 3 is the indicative flowchart according to a kind of method 300 of wireless communication of the embodiment of the present application.As shown in figure 3, This method 300 includes herein below.

310, wireless device receives the control frame transmitted on wireless channel, and the recipient of the control frame is not described wireless Equipment, the wireless device belong to the first Basic Service Set.

320, after the control frame is received on the wireless channel, the wireless device is received on the wireless channel Communication message physical header, the physical header include the communication message belonging to Basic Service Set short identifier；It is described Control frame and the communication message are from same equipment.

Alternatively, when the media access control address that the control frame includes is not belonging to the first address properties table, The second address properties table is inquired about, the second address properties table includes multiple media for being not belonging to first Basic Service Set and visits Ask control address, when the media access control address that the control frame includes belongs to the second address properties table, compare institute The relation for receiving power and first threshold of control frame is stated, when the reception power of the control frame is greater than or equal to first threshold When, the duration Duration in the control frame sets first timer, when the reception power of the control frame is small , can be with spatial reuse when the first threshold；When the media access control address that the control frame includes is not belonging to described During double-address attribute list, the relation for receiving power and first threshold of the control frame, when the reception work(of the control frame When rate is greater than or equal to first threshold, the duration Duration in the control frame sets first timer, described Second timer is general networks allocation vector timer rNAV timers, and the first timer is used to indicate the wireless communication There is the signal transmission for being not belonging to first Basic Service Set on road, when the reception power of the control frame is less than first threshold During value, the duration Duration in the control frame sets the first timer, at this time, not can determine that described The basic service set attribute of control frame, it is OBSS frames simply temporarily to think the control frame, need to according to follow-up information again into Row judges.

The wireless device is provided with after NAV timers because receiving a request to send frame RTS frame, in order to avoid The receiving terminal of RTS frames does not send clearly transmittable frame CTS frames because the reason such as interference does not receive this RTS frame, causes information to pass Defeated failure, then the wireless device can continue to intercept channel at the appointed time.If phase is not heard at the appointed time The clearly transmittable CTS frames answered, but listen to what the wireless device was sent within the stipulated time after listening to the RTS frames Subsequent transmission frame, illustrates that the RTS frames are sent successfully, then the set first timer retains.If listening to State control frame exceed schedule time in do not hear that the wireless device for sending the control frame sends subsequent transmission frame, illustrate the control Frame processed sends failure, then the wireless device recovers the initial value of the first timer.If after the stipulated time, listen to The corresponding communication message physical header of the control frame, the physical header include the short of the Basic Service Set belonging to the communication message The transmission direction designator of identifier and the communication message.The information then included according to the communication message physics, identifies institute State the communication message whether communication message belongs to first Basic Service Set.

330, when the media access control address that the wireless device includes according to the control frame can not judge the control When whether frame processed belongs to the control frame of first Basic Service Set, and belonging to the communication message that includes of the physical header Basic Service Set short identifier it is identical with the short identifier of first Basic Service Set, and can not according to the physical header When the transmission direction for determining the communication message is upstream or downstream, the wireless device continues to the thing of the communication message Manage layer service data unit；The basic clothes that the wireless device is included according to the physical layer service data received Business set identifier, determines whether the communication message belongs to first Basic Service Set, when the communication message is not belonging to institute When stating the first Basic Service Set, the wireless device determines short identifier and the institute of the Basic Service Set belonging to the communication message There is conflict in the short identifier for stating the first Basic Service Set.

Alternatively, the short identifier when the Basic Service Set belonging to the communication message physical header and the wireless device When the short identifier of Basic Service Set is identical, continues and receive the physical layer service data PSDU of the communication message, parse The physical layer service data PSDU, the PSDU include at least a data frame or management frame, the data frame or pipe The mac frame head of reason frame includes BSSID, according to the BSSID, determines whether the communication message belongs to the first Basic Service Set Communication message.

When the media interviews of the BSSID that the physical layer service data PSDU includes and first Basic Service Set When controlling address identical, determine that the communication message belongs to the communication message of the first Basic Service Set；Or when the physical layer takes When the BSSID of data cell of being engaged in PSDU is different from the media access control address of first Basic Service Set, determine described logical Letter message is not belonging to the communication message of the first Basic Service Set, i.e., described communication message is OBSS messages.If described wirelessly set Standby to parse the physical layer service data, then the wireless device can not determine whether the communication message belongs to the One Basic Service Set, then no longer intercept the wireless channel within first timer remaining time.

Alternatively, when the PSDU BSSID and first Basic Service Set access point AP media access controls Location is different, when determining that the communication message is not belonging to the communication message of the first Basic Service Set, then basic service set identification BSS Color conflicts, it should changes the first basic service set identification BSS Color.When the wireless device is the described first basic clothes During the access point AP of business collection, the wireless device changes the first basic service set identification BSS Color；When the wireless device is During site STA in the first Basic Service Set, the wireless device sends first to the access point AP of the first Basic Service Set and refers to Show information, first configured information is used to indicate that described access point AP changes the first basic service set identification BSS Color.

Alternatively, the communication message physical header can also include transmission direction designator.When the physical header includes institute When stating transmission direction designator, the wireless device can determine the control frame/communication according to the transmission direction designator Whether message belongs to the first Basic Service Set.Determine that the transmission direction of the communication message is according to the transmission direction designator During upstream or downstream, determine that the control frame/communication message is not belonging to the communication message of first Basic Service Set.According to institute Transmission direction designator is stated not can determine that when the transmission direction of the communication message is upstream or downstream, it is necessary to continue to described PSDU, according to the MAC Address of the PSDU Basic Service Sets included, determines whether the control frame/communication message belongs to One Basic Service Set.

Therefore, according to the embodiment of the present application, equipment is when receiving a control frame, because can be sentenced according to address attribute list Break the basic service set attribute of the control frame, can identify a media access control address without first Basic Service Set The basic service set attribute of control frame, can be easier the control frame that identification is not belonging to the first Basic Service Set；When cannot according to institute The media access control address that stating control frame includes identifies whether the control frame belongs to the control of first Basic Service Set During frame, and the short identifier of the Basic Service Set belonging to the communication message that includes of the physical header and described first basic When the short identifier of services set is identical, physical layer service data is parsed to identify the Basic Service Set category of the communication message Property, and can also determine the presence of basic service set identification conflict, in order to which access point changes basic service set identification, carry The chance of high spatial multiplexing, improves system channel service efficiency.

Fig. 4 is the indicative flowchart according to a kind of method 400 of identification Basic Service Set of the embodiment of the present application.It is described Control frame is request to send frame RTS frames, and the communication message physical header is HE message physical headers.Formulating IEEE802.11ax (High Efficient, abbreviation HE) standard in order to improve WiFi system efficiency, defines new physical header Structure, wherein comprising basic service set identification BSS Color and uplink and downlink configured information, realizes spatial reuse and disappears to facilitate Non-reception side's power saving of breath.BSS Color are set to 6 bits, value is specified by AP at present equivalent to the short mark of a BSS.On The transmission direction of downlink instruction then instruction message is or STA to the AP from AP to STA.It is known as down direction from AP to STA, from STA to AP is known as up direction.Uplink and downlink instruction takes 1 bit.A kind of direct-connected transmission is but also defined in IEEE802.11, That is two STA for being associated with same AP, they can be with direct communication, without forwarding message by AP.In 802.11ax, directly Even transmission is indicated as downlink transfer in physical header, it is actually not downlink transfer certainly.One is operated in The substandard equipment of IEEE802.11 is referred to as HE equipment.Message/frame that one HE equipment judges to listen to is the first basic service The method for collecting message or OBSS is as follows：

If the WiFi message listened to includes HE physical headers (i.e. the physical header of 802.11ax forms), because HE physical headers In include BSS Color, if therefore BSS Color in the physical header heard it is identical with the BSS Color of oneself, be treated as One Basic Service Set message/frame, if the BSS Color and BSS Color of oneself in the physical header heard are differed, is considered as OBSS messages/frame.But the value of BSS Color is randomly assigned by access point AP, the BSS of different Basic Service Sets may be caused Color is the same, i.e. BSS Color conflicts.If BSS Color and the BSS Color phases of oneself in the physical header therefore heard Together, the first Basic Service Set message/frame is treated as, the message/frame that may be not belonging to one the first Basic Service Set is mistakenly considered Message/frame of first Basic Service Set, has missed the chance of spatial reuse.

If listening to control frame, message must use traditional physical frame formats to transmit including RTS, CTS, ACK etc., no New physical layer protocol head can be included, so that legacy wireless devices can understand this mac frame, realize backward compatibility.These message Physical header do not include BSS Color information, then the HE equipment intercepted can only judge from the mac address information in its mac frame head It is the first Basic Service Set message/frame or OBSS messages/frame.

As shown in figure 4, this method 400 includes herein below.

401, wireless device listens to a control frame, and two addresses are included at least in the control frame, receives address (Receiver Address, abbreviation RA) and send address (Transmitter Address, abbreviation TA).

402, judge to receive the address that address RA is the wireless device.

403, if receiving the address that address RA is the wireless device, receive and handle the control frame.

404, if receiving the address that address RA is not the wireless device, according to reception address RA and send address TA Identify whether the control frame belongs to first Basic Service Set.

Alternatively, according to the RTS recipient address included and/or sender address, identify whether the RTS is The media access control address of the access point of one Basic Service Set includes：If RA is the access point AP of the first Basic Service Set Media access control address BSSID, it is that STA in the first Basic Service Set BSS is sent to the first Basic Service Set to illustrate RTS AP's, RTS is the frame of the first Basic Service Set, and if TA can be added to address by TA not in the BSS attribute lists of address In BSS attribute lists, labeled as the first Basic Service Set address；If TA is the BSSID of the first Basic Service Set, illustrate that RTS is AP in first Basic Service Set is sent to the STA's of the first Basic Service Set, and RTS is the frame of the first Basic Service Set, and If RA can be added in the BSS attribute lists of address, labeled as the first Basic Service Set by RA not in the BSS attribute lists of address Address；If RA and TA are not the BSSID of the first Basic Service Set, inquiry MAC Address BSS attribute lists are to judge RTS No is the first Basic Service Set frame, as long as an address in RA and TA is determined as the first Basic Service Set address by tabling look-up, Then RTS is the first Basic Service Set frame, and if another address can be added into address BSS not in the BSS attribute lists of address Attribute list, and it is designated as the first Basic Service Set address.If RA and TA do not know that RTS is not in the BSS attribute lists of address No is the first Basic Service Set frame, is first judged as it not being the first Basic Service Set frame here.

Alternatively, according to the RTS recipient address included and/or sender address, identify whether the RTS is The media access control address of the access point of one Basic Service Set includes：Inquire about the first address properties table judge RTS whether be First Basic Service Set frame, the first address properties table include the BSSID of the first Basic Service Set, as long as one in RA and TA A address is determined as the first Basic Service Set address by tabling look-up, then RTS frames are the first Basic Service Set frame, and another address If not in the BSS attribute lists of address, address BSS attribute lists can be added into, and are designated as the first Basic Service Set address.If RA and TA does not know whether RTS is the first Basic Service Set frame, is first judged as here not then not in the BSS attribute lists of address It is the first Basic Service Set frame.

405, if the RTS belongs to the first address properties table, according to the duration Duration in the RTS frames Second timer is set, and the second timer is iNAV timers, and the first timer is used to indicate the wireless channel On have the signal transmission for belonging to the first Basic Service Set.Or the it is also contemplated that possibility of SR.After the second timer is set, The wireless device continues to intercept channel for a period of time, fixed to recover described first in the case of the RTS bust this When device.

406, if the RTS is not belonging to the first address properties table, whether the reception power of the RTS frames is more than the One threshold value, the first threshold are spatial reuse SR threshold values.If received OBSS message sinks power is more than the SR threshold values specified, That is spatial reuse threshold value, such as the SR threshold values are -62dBm, receive when power is less than this value just can with spatial reuse,

407, if the reception power is greater than or equal to the first threshold, according to the duration in the RTS Duration sets first timer, and the first timer is rNAV timers, and the second timer is used to indicate described There is the signal transmission for being not belonging to the first Basic Service Set on wireless channel.

408, if the reception power is less than first threshold, judge whether the control frame belongs to second according to RA and TA Address properties table, the second address properties table is with including at least one media access control for being not belonging to the first Basic Service Set Location MAC Address.Specifically, judge in step 304, the RA and the TA are not the BSSID of the first Basic Service Set, then RA and TA is searched in the second address properties table, if an address in RA and TA has been labeled as OBSS addresses, RTS frames For OBSS frames, at this time if another address can be added into address BSS attribute lists, and be designated as not in the BSS attribute lists of address OBSS addresses.If RA and TA do not know whether RTS is OBSS frames, is first judged here not in the second address properties table To be OBSS frames.If tabling look-up two addresses of discovery RA and TA all in the BSS attribute lists of address and there is different BSS attributes, This RTS frame is then considered as OBSS frames.

409, if the RTS belongs to the second address properties table, because the reception power of the RTS frames is less than described the One threshold value, can be with spatial reuse.

Alternatively, the wireless device as not receiving this RTS frame completely.

Alternatively, transmitting data in parallel in the period that can be indicated in the rts after the RTS terminates.

410, if the RTS is not belonging to the second address properties table, the duration Duration in the RTS First timer is set.

According to the regulation in existing standard, equipment is receiving a RTS there is provided after NAV, can continue to intercept channel, If not hearing corresponding CTS frames, but add CTS transmission times to hear in the SIFS times for harvesting 2 times of RTS intervals and send RTS frames Equipment send subsequent transmission frame, illustrate that RTS is sent successfully, then set rNAV timers retain.If the received biography of institute Defeated frame is HE frames, then when receiving the physical header of HE transmission frames, performs step 311.If harvest SIFS times of the RTS more than 2 times Do not hear that the equipment for sending RTS frames sends subsequent transmission frame after adding CTS transmission times, illustrate that RTS sends failure, then set RNAV timers can recover.Regulation RTS sends 2 times of SIFS times of interval and adds CTS transmission times in 802.11 standards of IEEE After can receive subsequent transmission frame.

411, wireless device listens to a HE physical header.

After frame hears that 2 times of SIFS of RTS frame periods add a CTS times, if receiving a HE physical header, and newly receive The reception power of the reception power and received RTS frames before of the physical header arrived is basically identical, illustrates RTS transmission success above , then set rNAV continuation.And identify whether the HE physical headers belong to the first Basic Service Set.

412, wireless device intercepts the situation for receiving a non-HE physical header, and the embodiment of the present application is ignored.

413, judge basic service set identification BSS Color in the HE physical headers and the where the wireless device Whether the basic service set identification BSS Color of one Basic Service Set are identical.If the Basic Service Set in the HE physical headers Identify the basic service set identification BSS Color of BSS Color and the first Basic Service Set where the wireless device not phase Together, then the HE physical headers are OBSS frames.

414, if the basic service set identification in the HE physical headers and the first basic clothes where the wireless device The basic service set identification for being engaged in collecting is identical, according to the transmission direction configured information in the HE physical headers, identifies the HE physics Whether head belongs to the first Basic Service Set.If there is the instruction for being explicitly indicated that this frame is uplink in the transmission direction configured information Information, then be not belonging to the first Basic Service Set, then the HE things certainly with reference to the judging result of preceding step, the HE physical headers Reason head is OBSS frames.

IEEE802.11ax (High Efficient, abbreviation HE, the refers to efficient WiFi) standards formulated are in order to carry High WiFi system efficiency, defines new physics header structure, wherein comprising the short identifier BSS Color of Basic Service Set and up and down Row configured information.Basic service set identification BSS Color are set to 6 bits equivalent to the short mark of a BSS at present, value by Access point AP is specified.The transmission direction of uplink and downlink instruction then instruction message is from access point AP to wireless device STA, or wirelessly Equipment STA to access point AP.It is known as down direction from AP to STA, up direction is known as from STA to AP.Uplink and downlink instruction takes 1 Bit.A kind of direct-connected transmission is also defined in IEEE802.11ax, i.e., two are associated with the wireless of same access point AP and set Standby STA, they can be with direct communication.In IEEE802.11ax, direct-connected transmission is indicated as downlink transfer in physical header, when So it is actually not downlink transfer.If the basic service set identification is identical with first basic service set identification, root Determine whether the physical header belongs to the first Basic Service Set according to uplink and downlink configured information, when the uplink and downlink configured information is upper During row, determine that the physical header is not belonging to the first Basic Service Set.

415, if the configured information for being explicitly indicated that this frame is uplink is not present in the transmission direction configured information, after continued access Receive the content behind HE physical headers, i.e. physical layer service data PSDU parts.Determine that can the wireless device parse PSDU。

416, if the wireless device cannot parse PSDU, residue of the wireless device in the first timer Do not have to intercepting the wireless channel in time.

417, if the wireless device can parse PSDU, it is determined that whether the PSDU includes the first Basic Service Set Media access control address.

418, if the PSDU includes the media access control address of the first Basic Service Set, update the first address category Property table, media access control address in PSDU from the HE physical headers to the first address properties table and/or institute after adding State the media access control address that the corresponding RTS frames of HE physical headers include.

419, after the first address properties table is updated, recover the first timer, according to continuing for the HE physical headers Time Duration sets second timer, and the second timer is used to indicating to have on the wireless channel that to belong to first basic The signal transmission of services set.

420, if the PSDU does not include the media access control address of the first Basic Service Set, the HE physical headers It is not belonging to the first Basic Service Set, the basic service set identification conflict.If the wireless device is the first Basic Service Set Access point, then the wireless device change the first basic service set identification BSS Color；If the wireless device is The website of first Basic Service Set, the wireless device send the first instruction message, institute to the access point of the first Basic Service Set State the first instruction message and be used for described access point change basic service set identification.

421, the second address properties table is updated, after adding the HE physical headers to the second address properties table The media access control address that media access control address and/or the corresponding RTS of the HE physical headers in PSDU include.
