Fig. 2A is the method flow diagram of the website dispatching method of the transmitted in parallel data provided in one embodiment of the invention, The website dispatching method of the transmitted in parallel data is mainly carried out by taking the access point 120 being applied in implementation environment shown in Fig. 1 as an example It illustrates.In fig. 2, the website dispatching method of the transmitted in parallel data includes the following steps:

Step 201, after receiving the scheduling request signaling that uplink website and end-to-end transmission website are sent, according to The scheduling request signaling of transmission marks off the website of at least one set of transmitted in parallel.

In general, access point is in order to according to the more websites of available scheduling of resource, and access point would generally be After receiving multiple scheduling request signalings, the step of just will do it step 201.

In addition, access point can receive in the scene of uplink website and end-to-end transmission website transmitted in parallel data The scheduling request signaling sent to uplink website and end-to-end transmission website, scheduling request signaling here can be Buffer-report signaling.

It, then can be with after access point receives the scheduling request signaling that uplink website and end-to-end transmission website are sent According to these uplink websites and end-to-end transmission website, the website of scheduling is determined.And in view of access point is in reception When the upstream data packet that row transmission website is sent, it is easy the end pair sent by end-to-end transmitting station to end-to-end receiving station The interference of end data packet, therefore, it is reasonable that access point needs to carry out each uplink website and each end-to-end transmitting station Scheduling, to reduce interference when access point receives the data of uplink website transmission.

Optionally, access point can according to the rule of scheduling, according to the website for sending the scheduling request signaling, mark off to The website of few one group of transmitted in parallel.One is generally included in the website of every group of transmitted in parallel for sending upper line number to the access point Uplink website and at least a pair of end-to-end transmitting station that data transmission is carried out by end-to-end sending method according to packet With end-to-end receiving station.

In a kind of common scene, since uplink website is when sending upstream data packet, usually occupy different Resource block, therefore the case where be usually not in transmitting data in parallel between each uplink website, therefore, access point needle To each uplink website, be required to determination can transmitting data in parallel therewith end-to-end transmitting station.In this scene In, it include a uplink website and at least a pair of end-to-end transmission in the website for every group of transmitted in parallel that access point divides Website and end-to-end receiving station.

In another common scene, when system uses uplink multi-users multiple-input and multiple-output (English: Multi-User When transmission mode Multiple-Input Multiple-Output, referred to as: MU-MIMO), multiple uplink websites can be with Different spatial flows is occupied on identical running time-frequency resource to be transmitted and do not interfere with each other.In this case, may exist At least two uplink websites carry out data transmission using the same time/frequency source block simultaneously, therefore in this scene, access It include at least one uplink website and at least a pair of end-to-end dispatching station in the website for every group of transmitted in parallel that point divides Point and end-to-end receiving station.

It refers to shown in Fig. 2 B, is the method flow diagram of the division website provided in one embodiment of the invention.Scheming In 2B, when access point marks off the website of at least one set of transmitted in parallel from the website for sending the scheduling request signaling, including such as Lower step:

Step 201a determines each uplink website for sending the scheduling request signaling and end-to-end transmitting station, And determine end-to-end receiving station corresponding with end-to-end transmitting station.

Access point can determine each uplink for sending the scheduling request signaling according to the scheduling request signaling received Transmit website and end-to-end transmitting station.

In one possible implementation, include and the end pair in the scheduling request website that end-to-end transmitting station is sent The corresponding send chain mark of transmitting station is held, which backs up in advance has the send chain of end-to-end sending method to identify, here Send chain identify the mark for uniquely determining the both ends website of end-to-end sending method, for example send chain mark can be by The mark of the end-to-end transmitting station of end-to-end data packet and the mark of end-to-end receiving station are sent with end-to-end sending method Composition.After access point obtains the send chain mark in scheduling request website, the send chain can be inquired and identify corresponding a pair End-to-end transmitting station and end-to-end receiving station.

In general, in end-to-end sending method, end-to-end transmitting station in end-to-end transmission website is to access Point sends scheduling request signaling.

In alternatively possible implementation, also end pair is included in the scheduling request signaling that end-to-end transmitting station is sent The mark for holding transmitting station, can store in access point it is each pair of carried out data transmission by end-to-end sending method it is end-to-end The corresponding relationship of transmitting station and end-to-end receiving station, when access point receives the scheduling that an end-to-end transmitting station is sent After demand signalling, then it can determine and send out according to the end-to-end transmitting station of storage and the corresponding relationship of end-to-end receiving station Give the end-to-end transmitting station of the scheduling request signaling corresponding end-to-end receiving station.

In another possible implementation, carries and be somebody's turn to do in the scheduling request signaling that end-to-end transmitting station is sent The mark of the end-to-end receiving station carried out data transmission between end-to-end transmitting station according to end-to-end sending method, access point It, then can be really according to the end carried in scheduling request signaling after receiving the scheduling request signaling that end-to-end transmitting station is sent The mark of opposite end receiving station determines end-to-end reception corresponding with the end-to-end transmitting station of the scheduling request signaling is sent Website.

Step 201b is successively tasted from the uplink website and end-to-end transmitting station determined according to scheduling rule Different uplink websites and end-to-end transmitting station are combined in examination, obtain different combinations.

It is a pair of comprising at least one uplink website and at least in each combination to be held by end-to-end sending method The end-to-end transmitting station and end-to-end receiving station that opposite end data packet is sent.

Scheduling rule said here is the money that access point sends data needs according to actually available bandwidth, each website Source block, the service priority of data that each website needs to send, network service quality (Quality of Service, At least one of) etc. QoS it is scheduled.It will be apparent that scheduling rule can also include other factors, the present embodiment is not right The factor of scheduling rule institute package definition is defined.

Since access point is that those of ordinary skill in the art can realize in the process being scheduled according to scheduling rule , therefore just repeat no more here.

Access point is successively attempted from the uplink website and end-to-end transmitting station determined according to scheduling rule Different uplink websites and end-to-end transmitting station are combined, different combinations is obtained, includes at least one in each combination Uplink website and at least a pair of end-to-end transmitting station that end-to-end data packet transmission is carried out by end-to-end sending method With end-to-end receiving station.

For example, when determine uplink website A1, end-to-end transmitting station B1, end-to-end transmitting station B2, end pair Transmitting station B3 is held, then the combination successively attempted can be with are as follows: uplink website A1, end-to-end transmitting station B1, end pair Hold transmitting station B2, end-to-end transmitting station B3；Alternatively, uplink website A1, end-to-end transmitting station B1, end-to-end transmission Website B2；Alternatively, uplink website A1, end-to-end transmitting station B1, end-to-end transmitting station B3；Alternatively, uplink station Point A1, end-to-end transmitting station B2, end-to-end transmitting station B3；Alternatively, uplink website A1, end-to-end transmitting station B1； Alternatively, uplink website A1, end-to-end transmitting station B2；Alternatively, uplink website A1, end-to-end transmitting station B3.

Again for example, when determine uplink website A1, uplink website A2, end-to-end transmitting station B1 and end pair Transmitting station B2 is held, then the combination successively attempted can be with are as follows: uplink website A1, uplink website A2, end-to-end Transmitting station B1, end-to-end transmitting station B2；Alternatively, website A1, uplink website A2, end-to-end transmission are transmitted in uplink Website B1；Alternatively, uplink website A1, uplink website A2, end-to-end transmitting station B2；Alternatively, uplink website A1, end-to-end transmitting station B1, end-to-end transmitting station B2；Alternatively, uplink website A1, end-to-end transmitting station B1；Or Person, uplink website A1, end-to-end transmitting station B2；Alternatively, uplink website A2, end-to-end transmitting station B1, end pair Hold transmitting station B2；Alternatively, uplink website A2, end-to-end transmitting station B1；Alternatively, uplink website A2, end-to-end Transmitting station B2.

That is, it is directed to each uplink website, it can be according to scheduling rule from least one end-to-end dispatching station The end-to-end transmitting station and the uplink website that different end-to-end transmitting station or different number are selected in point carry out Combination.

For MU-MIMO transmission mode, upstream data transmission can also be carried out extremely for using identical time/frequency source block Few two uplink websites, select different end-to-end transmissions according to scheduling rule from least one end-to-end transmitting station The end-to-end transmitting station of website or different number is combined at least two uplink website.

The same time/frequency source block used in divided every group of website can occupy whole bandwidth, can also occupy portion Divide bandwidth.

Each combination is identified as the website of one group of parallel transmission by step 201c.

Step 202, determine whether the website of every group of parallel transmission meets the condition being scheduled simultaneously.

The condition being scheduled simultaneously are as follows: access point receive uplink website send data when by same group in it is each The interference for the data that end-to-end transmitting station is sent by access point in the range of being received.

Access point determines whether the website of described group of transmitted in parallel meets by simultaneously in the website according to every group of transmitted in parallel May include the following two kinds mode when the condition of scheduling:

First way calculates described access point uplink in receiving described group and passes according to the website of every group of transmitted in parallel Signal to Interference plus Noise Ratio (the English: Signal to noise and for the upstream data packet that defeated website is sent Interference power ratio, referred to as: SINR), determine whether the SINR is greater than access point and is receiving uplink Required minimum SINR when the upstream data packet that website is sent.

Refer to is that the access point provided in one embodiment of the invention calculates signal and interference plus noise shown in Fig. 2 C The method flow diagram of ratio.In fig. 2 c, the described access point upper line number that uplink website is sent in receiving described group is calculated According to the SINR of packet, comprising:

Step 202a calculates the access point and receives uplink website in the group according to the website of every group of parallel transmission The power for sending upstream data packet, is denoted as the first reception power for the power.

In general, the transmission power that uplink website sends upstream data packet can be access point and the uplink The transmission power that website is made an appointment or uplink website is carried when sending scheduling request signaling.And uplink passes The transmission power that defeated website sends scheduling request signaling is also known to access point, in this way, access point is receiving uplink After reception power when the scheduling request signaling that website is sent, uplink website is sent to the transmission power of scheduling request signaling The reception power is subtracted, the channel loss between uplink website and access point is obtained；Access point utilizes uplink website The practical transmission power for sending upstream data packet subtracts the channel loss, obtains the access point and receives uplink station in the group Point sends the power of upstream data packet.

Step 202b calculates the access point and receives the end-to-end transmission for end-to-end transmitting station each in the group Website sends power when end-to-end data packet, which is denoted as the second reception power.

Since access point currently only has received the scheduling request signaling that end-to-end transmitting station is sent, access point is needed End-to-end transmitting station is calculated when actually sending end-to-end data packet, access point can receive the end-to-end transmitting station hair Power when the end-to-end data packet sent.

In practical applications, end-to-end in end-to-end transmitting station transmission in order to allow access point to estimate out access point Reception power when data packet usually carries power difference parameter in the scheduling request signaling that end-to-end transmitting station is sent, The power difference parameter is the transmission power and the end-to-end transmission when the end-to-end transmitting station sends the scheduling request signaling Website sends the difference between the actual transmission power of end-to-end data packet.

Refer to is that the calculating access point provided in one embodiment of the invention receives the end-to-end hair shown in Fig. 2 D The method flow diagram of the power to see off when sending end-to-end data packet.In figure 2d, access point calculates the access point and receives When power when the end-to-end transmitting station sends end-to-end data packet, it may include steps of:

Step 202b1, acquisition receive the reception power that the end-to-end transmitting station sends the scheduling request signaling.

Access point is when receiving the end-to-end transmitting station and sending the scheduling request signaling, available reception scheduling Reception power when demand signalling.

The reception power is subtracted the power difference parameter by step 202b2, this that obtained difference is determined as estimating connects Access point receives power when the end-to-end end-to-end data packet of the practical transmission of transmitting station.

For example, when end-to-end transmitting station is with power P_bWhen sending scheduling request signaling and being received by access point, connect Access point can use the power P for actually receiving the scheduling request signaling_rec1, end-to-end transmitting station is estimated to the logical of access point Road attenuation P_att1=P_b-P_rec1.When access point estimates channel attenuation amount of the end-to-end transmitting station to access point, access Point can estimate end-to-end transmitting station to the jamming power of access point, which is P_int=P_S2S-P_att1=P_b- Δ-P_att1=P_b-Δ-P_b+P_rec1=P_rec1-Δ。

Obviously, if P_bValue is the maximum power P that system allows_max, then the value is that all websites and access point are equal in system It can be seen that numerical value when, channel attenuation amount can be estimated to obtain.It should be understood that P_bIt can not also be all stations in the system The numerical value that point all may know that with access point, although channel attenuation amount is unable to estimate to obtain at this time, access point and end-to-end reception Website is still estimated that P_int。

Step 202c receives power and this Earth noise of access point for be calculated each second and sums, obtain and Value.

Since access point is when receiving uplink website using resource block transmission upstream data packet, it is each to will receive other End-to-end transmitting station sends the interference of end-to-end data packet using the resource block, therefore when access point calculates SINR, access Point needs will be calculated each second to receive power and this Earth noise of access point is summed.

Step 202d obtains the SINR by the first reception power divided by this and value.

For example, when the power of the upstream data packet of the access point AP uplink site STA 1 received is P_STA1@AP, the power P of the end-to-end data packet of the end-to-end transmitting station STA2 received_STA2@AP, this Earth noise of access point is P_Noise@AP, then SINR=P_STA1@AP/(P_STA2@AP+P_Noise@AP)。

Again for example, when the power of the upstream data packet of the access point AP uplink site STA 1 received is P_STA1@AP, the power P of the end-to-end data packet of the end-to-end transmitting station STA2 received_STA2@AP, the end-to-end transmission that receives The power P of the end-to-end data packet of site STA 3_STA3@AP, this Earth noise of access point is P_Noise@AP, then SINR=P_STA1@AP/ (P_STA2@AP+P_STA3@AP+P_Noise@AP)。

That is, the same uplink website is directed to, in the formula for calculating SINR, in addition to considering that access point is local Noise, it is also necessary to consider it is each may be with the transmission power of the end-to-end transmitting station of uplink website transmitted in parallel data.

The second way calculates described access point uplink in receiving the group according to the website of every group of transmitted in parallel The maximum interference power allowed when the upstream data packet that website is sent, determines whether the maximum interference power allowed is greater than access point The sum of reception power when the end-to-end data packet that each end-to-end transmitting station is sent in receiving described group.

The maximum allowed when calculating the described access point upstream data packet that uplink website is sent in receiving described group The mode of jamming power can be with are as follows: for group website, access point obtains the uplink for receiving that uplink website is sent in the group Reception power when data packet, this will receive power and receives the upstream data packet when institute that uplink website is sent divided by access point Obtained quotient, is subtracted this Earth noise of access point, obtains difference by the minimum SINR needed, using obtained difference as permission Maximum interference power.

For example, when the power of the upstream data packet of the access point AP uplink site STA 1 received is P_STA1@AP, the power P of the end-to-end data packet of the end-to-end transmitting station STA2 received_STA2@AP, the end-to-end transmission that receives The power P of the end-to-end data packet of site STA 3_STA3@AP, the Signal to Interference plus Noise Ratio that access point allows is SINR, access This Earth noise of point is P_Noise@AP, then meet the condition being scheduled simultaneously are as follows: P_STA1@AP/SINR-P_Noise@AP>(P_STA2@AP+ P_STA3@AP)。

Again for example, when the power of the upstream data packet of the access point AP uplink site STA 1 received is P_STA1@AP, the power P of the end-to-end data packet of the end-to-end transmitting station STA2 received_STA2@AP, access point allow signal with Interference plus noise ratio is SINR, this Earth noise of access point is P_Noise@AP, then meet the condition being scheduled simultaneously are as follows: P_STA1@AP/ SINR-P_Noise@AP>P_STA2@AP。

Optionally, maximum interference power can also be what access point and uplink website had been made an appointment, be also possible to It is obtained according to historical experience.

In one possible implementation, in the transmission mode of MU-MIMO, the transmitted in parallel station in determining one group When whether point meets the condition being scheduled simultaneously, the end-to-end transmission to uplink website each in the group and distribution is needed Website is determined, when each judgement meets the condition being scheduled simultaneously, then can determine that transmitted in parallel website accords in the group Close the condition being scheduled simultaneously.

Step 203, from each group website for meeting the condition being scheduled simultaneously, at least one set is selected according to scheduling rule Website.

When the website of one group of parallel transmission meets the condition being scheduled simultaneously, then show that access point allows the uplink of the group Website and end-to-end transmitting station transmitted in parallel data are transmitted, namely show access point uplink website in receiving the group When data, the interference of the data sent by end-to-end transmitting station each in the group within an acceptable range, therefore access point Can permit the group uplink website and end-to-end transmitting station transmitted in parallel data.

Step 204, broadcast transmission dispatch notification signaling, the dispatch notification signaling are used to dispatch according to scheduling rule selection Each website at least one set of website.

The each website being assigned in scheduled group in dispatch notification signaling can increase this in dispatch notification signaling The mark of a little websites, or increase in these websites the mark of uplink website and for identifying end-to-end dispatching station The mark of point and end-to-end receiving station.Here dispatch notification signaling is usually trigger- in 802.11ax standard Frame signaling.

It optionally, can also be specified for every group of website in addition at least one set of website of specified scheduling in dispatch notification signaling The time/frequency source block that every group of website can be used, in order to which these websites transmit data using specified time/frequency source block.

The dispatch notification signaling sends upstream data packet to the access point for triggering scheduled uplink website, also For informing that scheduled each pair of end-to-end transmitting station and end-to-end receiving station have the permission for sending end-to-end data packet.

That is, when a uplink website is receiving dispatch notification signaling, and determine that the dispatch notification is believed The mark for carrying the uplink website in specified scheduling this uplink website, such as the dispatch notification signaling is enabled, then is pressed Upstream data packet is sent to access point according to the power (for example power can be sent for the maximum of permission) that sends scheduled in advance. Alternatively, carrying instruction uplink website in dispatch notification signaling, this sends the transmission power of upstream data packet, uplink When transmitting website and receiving dispatch notification signaling, and determining that the dispatch notification signaling specifies scheduling this uplink website, Upstream data packet is sent to access point according to the transmission power indicated in dispatch notification signaling.

When end-to-end receiving station receives dispatch notification signaling, and in the specified tune in a manner of end-to-end of dispatch notification signaling When spending the end-to-end receiving station, determine whether to meet the transmission item for allowing end-to-end transmitting station to send end-to-end data packet Part, and when meeting allows the end-to-end transmitting station to send the transmission condition of end-to-end data packet, to corresponding end-to-end Transmitting station sends notice and sends signaling, which sends signaling and start end-to-end to connect to this for triggering end-to-end transmitting station It receives website and sends end-to-end data packet.

When end-to-end transmitting station receives dispatch notification signaling, and determine that the dispatch notification information is effective to itself, It then waits corresponding end-to-end receiving station to send notice and sends signaling.

Optionally, which sends in signaling and also carries sending method, and end-to-end transmitting station can be according to the sender Formula sends end-to-end data packet to end-to-end receiving station.Here sending method can carry the ginseng such as MCS, spatial stream number Number sends the present embodiment and is not defined to the parameter carried in sending method.

That is, when access point determine one group can parallel transmission website after, scheduled uplink website is straight It connects to access point and sends upstream data packet, and scheduled end-to-end receiving station also needs to further determine whether by uplink Transmit interference when website is sent notifies corresponding end-to-end transmitting station to the end pair if interference is within an acceptable range Receiving station is held to send end-to-end data packet.Due to access point estimated out receive uplink website send data when by Within an acceptable range, and end-to-end receiving station is also estimated out and is receiving what end-to-end transmitting station was sent for the interference arrived The interference being subject to when data also within an acceptable range, even if then uplink website and end-to-end transmitting station parallel transmission number According to interference suffered by access point and end-to-end receiving station within the acceptable range, therefore can permit uplink Website and end-to-end transmitting station carry out parallel transmission.

In conclusion the website dispatching method of the transmitted in parallel data provided in the embodiment of the present invention, by access point Place divides the website of request scheduling, includes at least one uplink website and at least one end in every group after division Opposite end transmitting station, access point determine whether the website of this group of transmitted in parallel meets the item being scheduled simultaneously for every group of website Part selects scheduled at least one set of website according to scheduling rule from each group website for meeting the condition being scheduled simultaneously； Since access point is by calculating, one group of website of scheduling is determined, interference caused by end-to-end transmitting station in this group of website Uplink website and end-to-end transmitting station in the range of access point license, therefore in this group of scheduled website can be with Transmitting data in parallel；Therefore it solves in the related technology because avoiding uplink website and end-to-end transmitting station identical as far as possible Moment and identical frequency send data simultaneously, lead to the wasting of resources, and the problem that transmitting efficiency is low；Reach and has been passed in uplink While defeated website and end-to-end transmitting station transmitted in parallel data, guarantee interfering with each other can between the data that generate parallel Receive in range, improves the effect of transmitting efficiency.

In one possible implementation, when the first interference ginseng that access point is determined for all uplink websites Number is respectively less than corresponding first predetermined threshold namely access point in the upstream data packet for receiving each uplink website transmission When, it will receive the larger interference that other end-to-end transmitting stations send end-to-end data packet, therefore in order to avoid uplink End-to-end transmitting station transmitted in parallel data in website and end to end system, access point can will be adjusted according to scheduling rule determination One of the uplink website of degree and end-to-end transmitting station.At this point, only being wrapped in the dispatch notification signaling of access point broadcast Include the mark of uplink website, either only comprising end-to-end transmitting station mark (or for utilize end-to-end sending method The mark of the end-to-end transmitting station of data transmission and the mark of corresponding end-to-end receiving station are carried out, or to utilize end pair Sending method is held to carry out the send chain mark of data transmission).Only comprising uplink website mark dispatch notification signaling only Upstream data packet is sent to access point for triggering uplink website, only the scheduling of the mark comprising end-to-end transmitting station is logical Know that information is only used for triggering end-to-end transmitting station to the end-to-end data packet of end-to-end receiving station transmission.This mode can Uplink website and end-to-end transmitting station transmitted in parallel are avoided, the dry of the upstream data packet that access point receives is in turn resulted in The case where disturbing.

Fig. 3 A is the method flow of the website dispatching method of the transmitted in parallel data provided in another embodiment of the present invention Figure, the website dispatching method of the transmitted in parallel data is mainly applied to the end-to-end receiving station in implementation environment shown in Fig. 1 It is illustrated for 162.In figure 3 a, the website dispatching method of the transmitted in parallel data includes the following steps:

Step 301, dispatch notification signaling is received, the website that access point allows to dispatch is assigned in the dispatch notification signaling.

In practical applications, end-to-end transmitting station corresponding with the end-to-end receiving station sends a tune to access point Demand signalling is spent, access point is after the scheduling request signaling for receiving uplink website and end-to-end transmitting station, according to tune Metric then determines broadcast transmission after one group of website, includes at least one in the one group of website determined by access point to the access The uplink website of point transmission upstream data packet and at least a pair of end for passing through end-to-end sending method and carrying out data transmission Opposite end transmitting station and end-to-end receiving station.And in this group of website of access point determination, access point, which is estimated out, to be received The end-to-end data packet that end-to-end transmitting station is sent in the group being subject to when the data that uplink website is sent in the group Interference is within an acceptable range.

Step 302, when the dispatch notification signaling specifies and dispatches end-to-end receiving station in a manner of end-to-end, determine whether Meet the transmission condition for allowing end-to-end transmitting station to send end-to-end data packet.

Transmission condition is that end-to-end receiving station is adjusted when receiving the data that end-to-end transmitting station is sent by other The interference for the data that the uplink website of degree is sent by the end-to-end receiving station in the range of being received.

End-to-end receiving station determines whether to meet the transmission item for allowing end-to-end transmitting station to send end-to-end data packet May include the following two kinds mode when part:

In first way, calculates the end-to-end receiving station and receiving the end-to-end data of end-to-end transmitting station transmission Signal to Interference plus Noise Ratio SINR when packet, determines whether to be greater than the end-to-end receiving station by the SINR that this is end-to-end receiving Transmitting station sends minimum SINR required when end-to-end data packet.

Calculate signal and interference of the end-to-end receiving station when receiving end-to-end transmitting station and sending end-to-end data packet Plus noise ratio SINR, including each step in Fig. 3 B.It refers to shown in Fig. 3 B, is provided in one embodiment of the invention The method flow diagram of Signal to Interference plus Noise Ratio is calculated in end-to-end receiving station, end-to-end receiving station is calculating the end pair End receiving station receive the end-to-end transmitting station send end-to-end data packet when SINR when, may include steps of:

Step 302a monitors jamming power in used time/frequency source block.

Time/frequency source block said here is usually to specify in the dispatch notification signaling of access point transmission, for example scheduling is logical Know at least one set of website of signaling middle finger degree of setting the tone, it can also be for the running time-frequency resource that every group of website specifies every group of website can be used Block, in order to which these websites transmit data using specified time/frequency source block.

Since uplink website is when sending upstream data packet, end-to-end receiving station may also can be received on these Row data packet, therefore, end-to-end receiving station can monitor uplink website sending generated when upstream data packet it is dry Disturb power.

Uplink website said here is to share with end-to-end transmitting station corresponding to the end-to-end receiving station The uplink website of same resource block.

Step 302b, when obtaining the end-to-end receiving station and receiving the end-to-end data packet that the end-to-end transmitting station is sent Reception power.

Optionally, it is sent if the end-to-end receiving station received the end-to-end transmitting station according to end-to-end sending method Data packet, then the end-to-end receiving station can be sent according to history, determine that it is end-to-end to receive this in history transmission process Reception power when the end-to-end data packet that transmitting station is sent.

Optionally, if the end-to-end transmitting station is sent out according to end-to-end sending method to the end-to-end receiving station for the first time Sending end opposite end data packet, the end-to-end transmitting station is when transferring demand signalling to access point transmission, in the scheduling request signaling In can carry transmission power parameter, which is used to indicate the end-to-end transmitting station and end-to-end will connect to this Receive the transmission power that website sends end-to-end data packet.Access point is dispatching the end-to-end transmitting station and end-to-end receiving station When, this can be carried in the dispatch notification signaling of broadcast and transfer the transmission power parameter carried in demand signalling.It is corresponding, it is end-to-end Receiving station then can be according between the transmission power parameter and the end-to-end transmitting station and end-to-end receiving station of estimation Channel loss, determine connecing when the end-to-end receiving station receives the end-to-end data packet that the end-to-end transmitting station is sent Receive power.

Step 302c obtains the SINR by the reception power divided by the jamming power.

In the second way, calculates the end-to-end receiving station and permit when receiving the data that the end-to-end transmitting station is sent Perhaps maximum interference power, determines whether the maximum interference power of the permission is greater than the end-to-end receiving station and is adjusted receiving Reception power when the upstream data packet that the uplink website of degree is sent.

Optionally, maximum interference power, which can be, is calculated according to historical experience or historical information.

Optionally, maximum interference power can also be that agreement or standard (such as 802.11ax) arrange a fixed threshold. Namely it can be determined that whether the fixed threshold is greater than end-to-end receiving station and is receiving scheduled uplink website transmission Upstream data packet when reception power.

Step 303, when meeting the transmission condition for allowing the end-to-end transmitting station to send end-to-end data packet, to the end Opposite end transmitting station sends notice and sends signaling, which sends signaling and start for triggering the end-to-end transmitting station to the end Opposite end receiving station sends end-to-end data packet.

When meeting the transmission condition for allowing the end-to-end transmitting station to send end-to-end data packet, show end-to-end reception The interference that website is subject to when receiving data within the acceptable range, therefore can send notice to the end-to-end transmitting station Signaling is sent, starts to send end-to-end data packet to the end-to-end receiving station to trigger the end-to-end transmitting station.
