Existing WiFi communication standard is a kind of wireless communication standard based on time-division and competition, the mechanism that i.e. equipment all in network is all made of competition sends WiFi message, specifically, when some equipment inside WiFi network has WiFi message to be sent to need to send, assuming that the equipment is equipment A, WiFi message equipment A to be sent is WiFi message 1, then equipment A can randomly choose a numerical value as counting initial value in the numberical range of permission, and with regular hour unit monitor channel, if channel idle (does not have other WiFi message transmitted or (the stronger noise refers to that the intensity of the signal of noise is greater than the noise of preset threshold value without stronger noise in channel, wherein, preset threshold value can according to network internal parameter determine a threshold value.Above-mentioned stronger noise for example can be the message sent using Bluetooth technology), then equipment A subtracts one for initial value is counted；If (i.e. channel is transmitting other WiFi message to channel busy or there are stronger noises, assuming that other WiFi message transmitted are WiFi message 2), then equipment A pause counts, until when channel idle (end of transmission or stronger noise disappear WiFi message 2), equipment A can just be further continued for counting downwards, until equipment A, which is determined, sends WiFi message 1, and passes through transmission WiFi message 1 when counting initial value reduces to 0.

For above equipment A when passing through transmission WiFi message 1, other equipment are in the machine using competition When system sends message, after listening to the WiFi message 1 transmitted in channel, counting will be suspended, until after 1 end of transmission of WiFi message (i.e. after channel idle), other equipment just will continue to count, WiFi message is sent by channel again until counting after initial value reduces to 0, to ensure that only one each WiFi message is being transmitted in channel.

However, each equipment in above-mentioned WiFi network is when sending WiFi message using the mechanism of above-mentioned competition, there can only be a WiFi message transmitting every time in channel, and each equipment is required to just can determine that after counting initial value and reducing to 0 and sends WiFi message, although this mode can guarantee that the communication inside WiFi network is normally carried out, the frequency efficiency of WiFi network is lower.

The third situation: if the transport-type of first message is indirectly connected transmission message, the transport-type of second message is indirectly connected transmission message, then the first equipment, which is determined, does not send second message by the first channel when the second equipment sends first message by the first channel.

Specifically, as stated above, the first equipment is the sender of second message, and the second equipment is first The sender of message.

When the transport-type of above-mentioned first message is indirectly connected transmission message, i.e., first message can be AP to the STA downstream message transmitted or broadcast message, or the upstream message that STA is transmitted to AP, that is to say, that the message that first message is transmitted between STA and AP；If the transport-type of second message is also indirectly connected transmission message at this time, that is, second message is also the message of the transmission between STA and AP, since AP cannot carry out messaging simultaneously, then when the transport-type of first message is indirectly connected transmission message, when the transport-type of second message is also indirectly connected transmission message, first equipment, which is assured that, does not send second message by the first channel when the second equipment sends first message by the first channel, continues to send second message using the method (mechanism of competition) for sending message in existing WiFi network.

Method for spacial multiplex provided in an embodiment of the present invention, first equipment passes through the physical header for the first message transmitted in the first channel of monitoring, the transport-type of available first message, so as to the transport-type of first message be indirectly connected transmission message, the transport-type of second message is direct-connected transmission message, or, the transport-type of first message is direct-connected transmission message, when the transport-type of second message is direct-connected transmission message or indirectly connected transmission message, it determines and second message is sent by the first channel when the second equipment sends first message by the first channel, method for spacial multiplex i.e. provided in an embodiment of the present invention, it does not need to wait until that counting initial value reduces to 0 again, it can be while the first transmission first message, pass through the first transmission second message, realize the spatial reuse of network internal, improve net The availability of frequency spectrum of network.

In the prior art, it can also include that downstream transmission indicates in the physical header of above-mentioned first message, downstream transmission instruction is for when first message is indirectly connected transmission message, when the message transmitted between as STA and AP, for further indicating that first message is the upstream message that STA is transmitted to AP, also It is for AP to the STA downstream message transmitted or broadcast message.It should be noted that, no matter first message is indirectly connected transmission message or direct-connected transmission message, and the network identity where the second equipment is the mark of AP, simultaneously, when above-mentioned first message is the indirectly connected transmission message of uplink, the mark of third equipment is also the mark of AP.Therefore when above-mentioned first message is the indirectly connected transmission message of uplink, the mark of network identity and the third equipment where second equipment is identical.

Then in order to save first message physical header expense, in S201, optionally, when in the physical header of first message including downstream transmission instruction, and the downstream transmission instruction characterization first message be upstream message when, if in the physical header of above-mentioned first message including the network identity where the second equipment, it then can not include the mark of third equipment, in this way, when the first equipment is in the physical header for getting first message, it can be according to the mark of network identity and the determining third equipment of downstream transmission instruction where the second equipment carried in the physical header of first message.Optionally, under same scene, if include the mark of third equipment in the physical header of above-mentioned first message, it then can not include the network identity where the second equipment, in this way, when the first equipment is in the physical header for getting first message, can be indicated to determine the network identity where the second equipment according to the mark and downstream transmission of the third equipment carried in the physical header of first message.

S202: the first equipment obtains the transport-type of first message according to direct-connected transmission instruction.

Wherein, the specific implementation procedure of S202 may refer to the description of above-described embodiment three, and details are not described herein.

S203: the first equipment judges whether the first equipment and the second equipment belong to the same network according to the network identity where the second equipment.If so, executing S204；If it is not, then terminating process.

Specifically, when above-mentioned first equipment is from after getting the network identity where the second equipment in the physical header of first message, the first equipment can determine whether oneself and the second equipment belong to the same network according to the network identity where oneself of itself storage and the network identity where the second equipment got.Optionally, can determine whether the first equipment and the second equipment belong to the same network whether the network identity where the network identity at place and the second equipment is identical by judging the first equipment.

S204: the first equipment determines whether the first equipment is different from third equipment according to the mark of third equipment.If so, executing S205；If it is not, then executing S208.

Specifically, after above-mentioned first equipment gets the mark of third equipment from the physical header of first message, first equipment can be according to itself mark of itself of storage and the mark of the third equipment got, determine whether oneself different from third equipment, that is, judge the first equipment whether be first message recipient. When the first equipment show that the first equipment is identical as third equipment according to the judgement of the mark of third equipment, that is, illustrate that the first equipment is exactly third equipment, that is to say, that the first equipment is the recipient of first message, then executes S208；When the first equipment obtains the first equipment and third equipment difference according to the judgement of the mark of third equipment, that is, illustrating the first equipment not is third equipment, that is to say, that the first equipment is not the recipient of first message, then executes S205.Optionally, can identify whether identical to determine whether the first equipment and third equipment are different by the mark and third equipment for judging the first equipment.

It should be noted that the execution of above-mentioned S202, S203 and S204 can in no particular order sequentially.

Historical path when S205: the first equipment determines that the first equipment monitors the message of third equipment transmission according to the mark for the third equipment for including in the physical header of neighbor information and first message is lost；Wherein, the corresponding relationship between historical path loss and the mark of other equipment when neighbor information is the message of the first equipment monitoring other equipment transmission.

Specifically, when the first equipment is determining and third equipment difference, that is the first equipment determines oneself not when being the recipient of first message, first equipment can be according to the mark for getting third equipment, itself storage neighbor information in search the first equipment monitor third equipment send message when historical path loss, that is, the message signal strength attenuation degree.

It should be noted that the corresponding relationship between the mark of multiple equipment is lost in historical path when including the message for the multiple equipment transmission that the first equipment is monitored in the neighbor information of above-mentioned first equipment storage.

S206: the first equipment is according to the transport-type of the transport-type of first message, the first equipment second message to be sent, and, first equipment monitors the historical path loss when message that third equipment is sent, it is determined whether sends second message by the first channel when the second equipment sends first message by the first channel.

Optionally, first way: the first equipment can be first according to the transport-type of first message, the transport-type of first equipment second message to be sent determines whether to send second message by the first channel when the second equipment sends first message by the first channel, and when determining transmission second message, historical path when further monitoring the message of third equipment transmission according to the first equipment is lost, whether the result for " sending second message by the first channel when the second equipment sends first message by the first channel " determined by before determining is accurate, if accurate, then the first equipment, which determines, sends second message.

Optionally, the second way: historical path loss when the first equipment first can also monitor the message of third equipment transmission according to the first equipment determines whether to send first message by the first channel in the second equipment When by the first channel send second message, and after determining transmission second message, whether the result for " sending second message by the first channel when the second equipment sends first message by the first channel " determined by before further determining according to the transport-type of the transport-type of first message, second message is accurate, if accurate, the first equipment, which determines, sends second message.

Following specific explanations are directed to above-mentioned second of implementation, specifically:

In the present embodiment, above-mentioned first equipment can be the equipment with fixed transmission power, i.e. the transmission power that the first equipment sends second message is constant power.

After historical path loss when above-mentioned first equipment determines that the first equipment monitors the message of third equipment transmission, historical path when sending power, the message that the first equipment monitoring third equipment is sent of first equipment second message according to transmitted by oneself is lost, determine whether reception power when third equipment monitors second message is greater than or equal to preset threshold value, and determined whether to send second message by the first channel when the second equipment sends first message by the first channel according to identified result, specifically:

Historical path loss when the transmission power of second message transmitted by oneself can be monitored the message of third equipment transmission with the first equipment by above-mentioned first equipment is subtracted each other, obtain reception power when third equipment monitors second message, reception power when if the third equipment obtained monitors second message is greater than or equal to preset threshold value, if then the first equipment of explanation sends second message using above-mentioned fixed transmission power, the path loss when second message that third equipment the first equipment of monitoring is sent is smaller, that is, for third equipment, the signal strength of second message may be stronger, i.e. the transmission of the first equipment may will affect third equipment and receive first message, therefore, when the reception power when third equipment monitors second message is greater than or equal to preset threshold value, it then determines and does not send the by the first channel in the second equipment Second message is sent by the first channel when one message, terminates process；Wherein, above-mentioned preset threshold value can be determined according to the parameter of the network internal where the first equipment.

Reception power when if the third equipment obtained monitors second message is less than preset threshold value, if then the first equipment of explanation sends second message using above-mentioned fixed transmission power, the path loss when second message that third equipment the first equipment of monitoring is sent is larger, that is, for third equipment, the signal strength of second message is weaker, that is the transmission of the first equipment will not influence third equipment and receive first message, therefore, when the reception power when third equipment monitors second message is less than preset threshold value, then the first equipment, which is determined, sends second message by the first channel when the second equipment sends first message by the first channel, further, first equipment " sends first by the first channel in the second equipment determined by can further determining that again according to the transport-type of first message and the transport-type of second message Pass through when message Whether the result of the first channel transmission second message " is accurate; when the first equipment is also determined when the second equipment sends first message by the first channel according to the transport-type of first message and the transport-type of second message through the first channel transmission second message; the result for " passing through the first channel determined by before illustrating when the second equipment sends first message by the first channel and sending second message " is accurate; then the first equipment, which determines, sends second message, thereby executing S207.

S207: the first equipment sends second message.

Specifically, after the first equipment determines and sends second message by the first channel when the second equipment sends first message by the first channel, it can be while first message be transmitted, second message is transmitted in the first channel, without waiting until that counting initial value reduces to 0, improves the availability of frequency spectrum of network again.After having executed above-mentioned S207, then terminate.

After having executed above-mentioned S207, then terminate.

S208: the first equipment continues to the remainder of first message.

Specifically, then the first equipment stops executing spatial reuse, and continues to the remainder of first message when above-mentioned first equipment judges the first equipment according to the mark of third equipment for the recipient of first message.After having executed above-mentioned S208, then terminate.

Method for spacial multiplex provided in an embodiment of the present invention, by the mark that direct-connected transmission instruction and third equipment are arranged in the physical header of first message, so that when the physical header for the first message that the first equipment is being transmitted in monitoring the first channel, can be determined by the third device identification in the physical header of first message the first equipment whether be first message recipient, when the first equipment is not the recipient of first message, it just can further pass through the transport-type of first message, the transport-type of second message and the first equipment monitor the historical path loss when message that third equipment is sent, it determines whether to send second message by the first channel when the second equipment sends first message by the first channel.Therefore, method for spacial multiplex provided in an embodiment of the present invention improves the success rate of the spatial reuse of network internal on the basis of realizing the spatial reuse of network internal.

Optionally, on the basis of above-described embodiment four, before above-mentioned S206, this method can also include the following steps: the first equipment judges whether the 4th equipment different from third equipment according to the mark of third equipment, that is, judge second message recipient whether be first message recipient；Wherein, the first equipment is the sender of second message, and the 4th equipment is the recipient of second message, and the second equipment is the sender of first message, and third equipment is the recipient of first message.

Specifically, when above-mentioned first equipment gets the mark of third equipment from the physical header of first message Later, the first equipment can according to itself storage the 4th equipment mark and the third equipment got mark, determine whether the 4th equipment different from third equipment, that is, judge second message recipient whether be first message recipient.When the first equipment judges that the 4th equipment is identical as third equipment according to the mark of third equipment, illustrate that the 4th equipment is exactly third equipment, i.e. the recipient of second message and the recipient of first message are the same equipment, that is third equipment is both the recipient of first message, is also the recipient of second message.Therefore, when the 4th equipment is identical as third equipment, the first equipment stops executing spatial reuse, terminates process；When the first equipment judges the 4th equipment different from third equipment and the first equipment and third equipment difference according to the mark of third equipment, that is the recipient of second message is also not the recipient of first message and when the sender of second message is also not the recipient of first message, then executes S206.In the present embodiment, when the first equipment is not the recipient of first message, when the 4th equipment is also not the recipient of first message, the first equipment just can further execute spatial reuse, the success rate of the spatial reuse of network internal is further improved, that is, improves second message and sends successful probability.

Optionally, on the basis of above-described embodiment four, the physical header of first message can also include the mark for sending the second equipment of first message, wherein, the mark of second equipment can be the short mark of the second equipment, the mark of second equipment can be set in the HE-SIG of the physical header of first message, also the other positions in the physical header of first message can be set, then before above-mentioned S206, this method can also include the following steps: the first equipment according to the mark of the second equipment, determine whether the 4th equipment for receiving second message is different from the second equipment, judge that the recipient of second message is the sender of first message；If so, S206 is executed, if it is not, then terminating process.Wherein, the first equipment is the sender of second message, and the 4th equipment is the recipient of second message, and the second equipment is the sender of first message, and third equipment is the recipient of first message.

Specifically, after above-mentioned first equipment gets the mark of the second equipment from the physical header of first message, first equipment can be according to the mark of the 4th equipment of itself storage and the mark of the second equipment got, determine whether the 4th equipment is different from the second equipment, that is, judges that the recipient of second message is the sender of first message.When the first equipment judges that the 4th equipment is identical as the second equipment according to the mark of the second equipment, illustrate that the 4th equipment is exactly the second equipment, i.e. the recipient of second message and the sender of first message are the same equipment, therefore, when the 4th equipment is identical as the second equipment, first equipment stops executing spatial reuse, terminates process；When the first equipment judges the 4th equipment and the second equipment difference according to the mark of the second equipment, illustrates that the recipient of second message is not the sender of first message, then execute S206.In the present embodiment, when the 4th equipment is not the sender of first message, the first equipment is Spatial reuse can be further executed, the success rate of the spatial reuse of network internal is further improved, that is, improves second message and sends successful probability.
