Description

A kind of channel resource indicating means and device

Technical field

The application is related to wireless communication technology field, more particularly to a kind of channel resource indicating means and device.

Background technology

In WiFi of future generation (Wireless Fidelity, Wireless Fidelity) the standard 802.11ax for currently formulating In, in order to improve efficiency of transmission, (Uplink Multiple User, up-link is multiplex to introduce UL MU Family) transmission mechanism, including UL OFDMA (Orthogonal Frequency Division Multiple Access, OFDM) and UL MU-MIMO (how defeated Multiple Input Multiple Output, multi input is Go out).For UL MU transmission, it is necessary to AP (Access Point, access point) sends trigger frame (Trigger) To carry out scheduling of resource.According to the resolution being currently discussed, when STA (Station, website) is received for touching During the trigger frame of hair UL MU transmission, if STA determines NAV (the Network Allocation of oneself Vector, network allocation vector) it is 0, or determine that values of the NAV of oneself more than 0 and NAV is basis Set from the frame that the equipment in this BSS (Basic Service Set, Basic Service Set) sends, then may be used To respond the trigger frame for receiving, i.e., UL data are sent in the resource of triggering frame scheduling.If STA determines Values of the NAV of oneself more than 0 and NAV is set according to the frame sent from the equipment in this BSS , then STA is not responding to the trigger frame for receiving, i.e., UL data are not sent in the resource of triggering frame scheduling. For a STA, other BSS outside the BSS associated by it are also called OBSS (Overlapping BSS, overlaps BSS).

Under the scene of equipment dense distribution, when STAs of the AP in its signal cover is scheduled, The NAV of one STA has very maximum probability to be set according to the frame sent from the equipment in this BSS, But what the frame sent according to the equipment in OBSS was set, the STA for being particularly at cell edge is more susceptible to Equipment influence in OBSS.Now, in order to solve the problem, in the prior art, STA can be used Per channel NAV (per-channel NAV) mechanism, as each channel setting one is corresponding with the channel NAV, STA can by different NAV distinguish different channels whether miscellaneous equipment is reserved, so, STA just can distinguish whether respective channels idle by each NAV, mentioned above such that it is able to avoid Problem.

Even if however, employ per-channel NAV mechanism, if AP dispatches at its own STA On NAV channels not corresponding to 0, then STA still will not respond the trigger frame of AP transmissions, equally The UL resources that AP can be caused to distribute to STA are wasted.

To sum up, because whether STA can determine according to NAV set by the frame from OBSS equipment Whether the UL MU scheduling trigger frame of AP transmission is responded, so as to cause may not to be rung when STA is scheduled The trigger frame that should be dispatched so that channel resource utilization rate is low.

Specific embodiment

The embodiment of the present application is described in detail with reference to Figure of description.

The embodiment of the present application can apply to WLAN (Wireless Local Area Network, WLAN), current WLAN accepted standards are the series of IEEE 802.11.WLAN can include one Or multiple Basic Service Sets, the network node that basic service is concentrated includes AP and STA.Each basic service Collection can include an AP and multiple STA for being associated with the AP.

AP, also referred to as access point or focus etc..AP is the access point that mobile subscriber enters cable network, Major deployments inside family, inside buildings and garden, typical covering radius be tens meters to rice up to a hundred, It is of course also possible to be deployed in open air.AP is equivalent to a connection wired network and the bridge of wireless network, its master It is to connect together each wireless network clients to act on, then by wireless network access network based on ethernet.Tool Body ground, AP can be terminal device or the network equipment with WiFi chip.Alternatively, AP can be with Support 802.11ax agreements, still optionally further, the AP can for support 802.11ac, 802.11n, The equipment of various WLAN protocols such as 802.11g, 802.11b and 802.11a.As a rule, certain is supported The equipment of agreement, while being also compatible with working in the old agreement of same frequency range.For example, working in 2.4GHz The 802.11n equipment of frequency range is typically also compatible with 802.11b and 802.11g, works in the 802.11n of 5GHz frequency ranges Equipment is typically also compatible with 802.11a.So-called certain agreement of equipment " compatibility ", i.e. equipment supports the agreement.

STA can be wireless communications chips, wireless senser or wireless communication terminal.For example：Support WiFi The mobile phone of communication function, the panel computer for supporting WiFi communication function, support WiFi communication function Set Top Box, the intelligent television for supporting WiFi communication function, support that the intelligence of WiFi communication function wearable sets The computer of vehicular communication equipment that is standby, supporting WiFi communication function and support WiFi communication function.It is optional Ground, website can support 802.11ax agreements, still optionally further, the website support 802.11ac, 802.11n, Various WLAN protocols such as 802.11g, 802.11b and 802.11a.

Fig. 1 is a system schematic for typical WLAN deployment scene, and Fig. 1 includes an AP With 3 STA, AP communicated with STA1, STA2 and STA3 respectively, constitutes a BSS.

In WLAN deployment scene, it is also possible to there is the situation that multiple BSS coexist.As shown in Fig. 2 being The system schematic of another typical WLAN deployment scene.In scene shown in Fig. 2, AP1, STA1, STA5 is in same BSS；AP2, STA2, STA3, STA4 are in same BSS.It is false If AP1 scheduling STA1 carried out on channel CH2 DL (Downlink, downlink) OFDMA, Scheduling STA5 carries out DL OFDMA transmission on channel CH1, and leads to first before data is transmitted Cross MU-RTS (Request To Send, request sends)/CTS (Clear To Send, clear to send) Mechanism is protected to downlink transfer.So, STA2 can receive the CTS frames from STA1, and NAV is configured according to the CTS frames from STA1.Carry out data transmission in AP1 and STA1 During, STA2 receives the trigger frame for UL MU scheduling of AP2 transmissions, and STA2 is in CH1 for scheduling On carry out UL transmission.As described above, because the NAV of STA2 is according to setting from OBSS Set by standby STA1, therefore the trigger frame whether STA2 responds AP2 transmissions is considered as the NAV of its own Whether it is 0, if STA2 determines that the NAV of itself is not responding to the triggering of AP2 transmissions more than 0, STA2 Frame.This causes the UL resources that AP2 distributes to STA2 to be wasted.But in fact, due to STA1 Different channels are scheduled in STA2, they completely can be with simultaneous transmission without interfering.

If the AP2 in Fig. 1 dispatches on CH2 STA2, then STA2 is if it is determined that its own correspondence It is not 0 in the NAV of CH2, then still will not responds the trigger frame of AP2 transmissions, also results in AP2 The UL resources for distributing to STA2 are wasted.

Regarding to the issue above, the embodiment of the present application provides a kind of channel resource indicating means and its device, uses To carry high channel resource use ratio, it is described more fully below.

In existing wlan system, sending node can be used on the whole frequency domain of radio resource channel OFDM technology transmits data, in order to the service transmission rate of wlan system, 802.11ax is substantially improved Standard will be on the basis of existing OFDM technology, further using OFDMA technologies.OFDMA Radio channel resource of eating dishes without rice or wine is divided into multiple orthogonal running time-frequency resource unit (Resource Unit, letter by technology Claim RU), shared in time between RU, it is orthogonal on frequency domain.In the standard for discussing, plan Radio resource channel with a width of 20MHz is at most divided into 9 orthogonal RU.AP can be with for the moment It is that different STA distributes orthogonal channel resource to carve, so that multiple STA can mutual interference-free Data are received or sent, flexibility ratio and utilization rate that channel is used is improved.Specifically, as shown in figure 3, originally A kind of time-frequency resource allocating schematic diagram of OFDMA transmission modes that application embodiment is provided.In Fig. 3, nothing 9 orthogonal RU, respectively first RU (#1RU), second RU have been divided on line channel resource (#2RU) ... the 9th RU (#9RU).Sending node transmit data when, in radio channel resource Whole frequency domain on common data is sent using OFDM modes：Legacy preamble and HE (high efficient, It is efficiently) leading, can on each RU that radio channel resource is divided by use OFDMA transmission modes To transmit different data cells.

Further, with reference to MU-MIMO technologies, AP can be on identical channel resource by multiple Space flow direction multiple STA carries out data is activation, it is also possible to receive from multiple STA on different spaces stream The data of transmission, so as to realize the parallel transmission of multi-user data, improve the concurrency of data transfer.Just In the standard for discussing, 8 spatial flows are could support up.

In wlan system, two kinds of transmission modes of OFDMA and MU-MIMO can exist simultaneously, i.e., OFDMA and MU-MIMO mixed transports.In the different subchannels or RU divided in OFDMA, AP dispatches corresponding one or more STA in different subchannels or RU, i.e. AP dispatches a STA Carry out OFDMA transmission on certain sub-channels or RU, or scheduling multiple STA in certain sub-channels or MU-MIMO transmission is carried out on RU.

The embodiment of the present application is applied to OFDMA, MU-MIMO and OFDMA and MU-MIMO is mixed Close the scene of transmission.As shown in figure 4, a kind of OFDMA and MU-MIMO that provide for the embodiment of the present application The schematic diagram of the scenario resources distribution of mixed transport.As shown in figure 4, using OFDMA technologies, will be whole Channel resource is divided into N number of RU of non-overlapping copies on frequency domain.Using MU-MIMO technologies, N number of Each RU in RU distributes a user equipment or distribution one group of group of user equipments.When on the RU When only distributing a user equipment, the transmission mode of the RU is single user (Single User, abbreviation SU) Transmission mode, including two kinds of possible situations of OFDMA and SU-MIMO；At least distributed when on the RU During two user equipmenies, the transmission mode of the RU is multi-user (Multiple User, abbreviation MU) biography Defeated pattern, including MU-MIMO, also including time reuse (Time Reuse).So-called time reuse, i.e., Multiple STA are transmitted in a time division manner in same subchannel or RU, this method just under discussion, at present Not yet used by standard.Therefore, MU transmission is described by taking MU-MIMO as an example in the present invention.

As shown in figure 4, being introduced so that user equipment is as STA as an example, whole channel resource is existed in Fig. 4 It is divided into N number of RU of non-overlapping copies, respectively first RU (#1RU), second RU (#2 on frequency domain RU) ... n-th RU (#N RU).On first RU (#1RU), distribution is one group of user Equipment group, this group of group of user equipments includes STA1, STA3, STA6, STA8 totally four user equipmenies, Wherein, STA1 is first STA of MU transmission modes (#1MU STA), and STA3 is second The STA (#2MU STA) of MU transmission modes, STA6 are the 3rd STA (#3 of MU transmission modes MU STA), STA8 is the 4th STA of MU transmission modes (#4MU STA).Similar, A user equipment STA2 is assigned with second RU (#2RU).At n-th RU (#N RU) On be assigned with a group of user equipments, this group of group of user equipments includes three user equipmenies, respectively STA5, STA4、STA7。

In the embodiment of the present application, the first equipment can be AP, and the second equipment can be STA.

When first equipment is AP, the first equipment can be that wireless terminal can also be catv terminal, for example may be used Being router, computer etc..It should be strongly noted that the WiFi equipment with central dispatching function AP is regarded as, for example, opening the terminal device of focus function, group is played the part of in WiFi Direct transmission The equipment of owner (Group Owner, GO) role.

When second equipment is STA, the second equipment can be that wireless terminal can also be catv terminal, for example may be used Think mobile phone, computer, panel computer, personal digital assistant's (English：personal digital Assistant, abbreviation：PDA), mobile internet device (English：Mobile Internet device, abbreviation： MID), wearable device and E-book reader (English：E-book reader) etc..

Based on above-mentioned discussion, as shown in figure 5, a kind of channel resource instruction side provided for the embodiment of the present application Method schematic flow sheet.

Referring to Fig. 5, the method includes：

Step 501：First equipment sends includes that the channel resource of channel resource configured information collects message, institute State channel resource configured information for indicate the first channel resource.

Step 601：Second equipment receives the money of the channel including channel resource configured information that the first equipment sends Message is collected in source, and the channel resource configured information is used to indicate the first channel resource.

In step 501, the first equipment can be sent including channel resource configured information by way of broadcast Channel resource collects message, and the channel resource collects message is used to trigger the second equipment feedback in the first channel Available channel in resource.

In the embodiment of the present application, channel resource configured information can serve to indicate that the second equipment is provided from the channel Determine usable idle channel in the first channel resource that source configured information is indicated.Accordingly, the second equipment After the channel resource collection message is received, the idle letter that can be used is determined from the first channel resource Road.

First channel resource can refer to frequency domain resource, for example, the first channel resource can be by multiple The frequency domain resource set of channel composition.Channel resource configured information can be include multiple channel logos optional Channel list is selected, so as to indicate the first channel resource, now first channel resource is that channel may be selected The set of the frequency domain resource of all channels in list.

For example, channel resource configured information indicates channel 1, channel 2, channel 5, now, channel 1 corresponding frequency domain resource, the corresponding frequency domain resource of channel 2, the corresponding frequency domain resource of channel 5 set can As the first channel resource.

Channel resource configured information can also be indicated with the mode of bandwidth, for example, indicated with 2 bits, and 00 represents 20MHz, 01 represents 40MHz, and 10 represent 80MHz, and 11 represent 160/80+80MHz.Wherein, 80+80MHz represents two discontinuous 80MHz channels.Channel resource indicated by this method is usual It is the channel comprising main (primary) channel.

Channel resource configured information can also be indicated with the mode of bitmap (Bitmap).For example, every in bitmap Bit correspondence 20MHz bandwidth, is set to 1 expression and uses corresponding 20MHz channels, and being set to 0 expression does not make With corresponding 20MHz channels.Assuming that AP supports 80MHz channels, then 4 bit maps, bitmap are used The set of middle the promising 1 corresponding 20MHz channels of bit can be used as the first channel resource.

It should be noted that in the embodiment of the present application, during channel can refer to the series standards of IEEE 802.11 Channel defined in any one standard.

The channel resource that first equipment sends can also include device identification list, the equipment in collecting message Identification list is used for second equipment of the instruction equipment mark in the device identification list according to the letter Road resource is collected message and sends available channel resources report message.Wherein, device identification can be the second equipment MAC (Media Access Control, media access control) address, it is also possible to being the second equipment AID (Association Identifier, association identification), can also be the PAID (Partial of the second equipment AID, partial association mark), or it is any other can be with the information of unique mark STA identity.

For example, the first equipment is it is determined that after the buffer status information (buffer status) of the second equipment, Need to be scheduled the second equipment UL MU transmission, wherein, the buffer status information is to indicate Stating the second equipment needs the information of data volume of the data transmitted, or required for second equipment transmission data Temporal information.Before UL MU transmission is scheduled to the second equipment due to the first equipment, it has been determined that Need to transmit the second equipment of data, therefore the first equipment can only need to determine to need to transmit the of data The available idle channel of two equipment, the channel resource that now the first equipment sends can include in collecting message Device identification list, being included in the device identification list completely or partially needs the second of transmission data to set Standby device identification.

By the above method, the first equipment can include that the channel resource of device identification list is collected by sending Message, it is determined that needing to send the available idle channel of the second equipment of data so that the first equipment is more directed to Property the available idle channel of equipment of determination second, it is to avoid need not send data the second equipment response first Equipment, so as to improve channel utilization.

In step 501, the first equipment can also collect message and refer to the second equipment by the channel resource for sending The 3rd channel resource corresponding with the second equipment is shown, so as to avoid the second channel resource of the second equipment choice Collide, improve channel utilization.Wherein, the 3rd channel resource can be frequency domain resource, can be with It is time and frequency zone resource, can also is frequency-code domain resource；The second channel resource can be frequency domain resource, Can be time and frequency zone resource, can also be frequency-code domain resource.The second channel resource is the 3rd letter The subset of road resource.

A frequency domain resource can be a RU in the embodiment of the present application；One time and frequency zone resource can be one The combination of individual RU and time period；One frequency-code domain resource can be RU and orthogonal sequence Combination.

Can be to include multiple when 3rd channel resource or the second channel resource are frequency domain resource The set of RU；When 3rd channel resource or the second channel resource are time and frequency zone resource, can be with It is the set for including multiple RU and the combination of time period；3rd channel resource or the second channel Can be the set of the combination for including multiple RU and orthogonal sequence when resource is frequency-code domain resource.

Need special instruction when, in the embodiment of the present invention, the element in channel resource set is likely located at not Same dimension, such as frequency domain, time and frequency zone, frequency-code domain, their common dimension are frequency domain.Therefore, this hair It is " subset ", the concept occured simultaneously between different channels resource in bright all embodiments, is all from for frequency domain 's.For example, time and frequency zone resource ignores time-domain information and only retains frequency domain information, frequency-code domain resource ignores code Domain information and only retain frequency domain information.It is therefore, above-mentioned that " second channel resource is the 3rd channel resource Physical meaning is represented shown in subset " is, " from frequency domain, second channel resource is the 3rd channel money The subset in source ".

First equipment can indicate corresponding with second equipment the by channel resource mapping indication information Three channel resources, it is also possible to which the 3rd letter corresponding with second equipment is indicated by the device identification list Road resource.

First equipment indicates the 3rd letter corresponding with second equipment by channel resource mapping indication information During road resource, the second equipment and corresponding with the second equipment are included in channel resource mapping indication information The corresponding relation of three channel resources, so that the second equipment determines the 3rd channel money corresponding with the second equipment The corresponding relation in source.

For example, the order of the device identification in the device identification list that the first equipment sends is device identification 1st, device identification 2, device identification 3.Now, the first equipment is indicated by channel resource mapping indication information Device identification 1 is corresponding with the RU1 in each channel, the RU2 in instruction equipment mark 2 and each channel Correspondence, instruction equipment mark 3 is corresponding with the RU3 in each channel.

It should be noted that channel resource mapping indication information can indicate same for two device identifications Three channel resources.

Channel resource mapping indication information can collect message and be sent to the second equipment by channel resource, also may be used To be individually sent to the second equipment, for example, sent by Beacon frames, or by single interaction message Send, the embodiment of the present application is not limited this.

First equipment indicates the 3rd channel corresponding with second equipment to provide by the device identification list During source, second equipment can be indicated to be located at the device identification according to the device identification of second equipment Order in list determines the 3rd channel resource corresponding with second equipment.Device identification is located at described setting Order in standby identification list can be made an appointment with the corresponding relation of the 3rd channel resource or standard is advised in advance It is fixed.

If the 3rd channel resource is the frequency domain resource for including multiple RU.The device identification list indicates position Each that the device identification of N can include with the first channel resource in the device identification list The RU correspondences of M in channel, N and M are positive integer.

For example, the first equipment by channel resource configured information indicate the first channel resource for channel 1, Channel 2, each channel includes 4 RU, respectively RU1, RU2, RU3, RU4.First equipment is needed Determine available idle channel the second equipment be respectively SAT1 (its device identification be device identification 1), SAT2 (its device identification is device identification 2), SAT3 (its device identification is device identification 3).First sets The order of the device identification in the device identification list that preparation is sent is device identification 1, device identification 2, equipment Mark 3.Now, device identification 1 can be corresponding with the RU1 in each channel, and device identification 2 can be with RU2 correspondences in each channel, device identification 3 can be corresponding with the RU3 in each channel.SAT1 Corresponding 3rd channel resource is the set of the RU1 in each channel, i.e. { RU1, channel 2 in channel 1 In RU1；Corresponding 3rd channel resources of SAT2 are the set of the RU2 in each channel, i.e. { channel RU2 in 1, the RU2 in channel 2 }；Corresponding 3rd channel resources of SAT3 are the RU3 in each channel Set, i.e., { RU3, the RU3 in channel 2 in channel 1 }.

In above-mentioned example, device identification can also be with the corresponding relation of RU：Device identification 1 can with it is every RU2 correspondences in individual channel, device identification 2 can be corresponding with the RU3 in each channel, device identification 3 can be corresponding with the RU4 in each channel.During corresponding 3rd channel resources of SAT1 are each channel The set of RU2, i.e. { RU2, the RU2 in channel 2 in channel 1 }；The corresponding 3rd channel moneys of SAT2 Source is the set of the RU3 in each channel, i.e. { RU3, the RU3 in channel 2 in channel 1 }；SAT3 Corresponding 3rd channel resource is the set of the RU4 in each channel, i.e. { RU4, channel 2 in channel 1 In RU4.

It should be noted that multiple equipment mark can be corresponding with the same RU in channel, i.e., positioned at institute State the device identification of N in device identification list and Q in the device identification list The RU of M is corresponding in each channel that device identification can include with the first channel resource, and Q is for just Integer.Such scheme typically can be in quantity of the quantity of the second equipment more than the RU that each channel includes Scene under implement.

Certainly, if quantity of the quantity of the second equipment more than the RU that each channel includes, in order to avoid Resource collision, the first equipment can send multiple channel resources collection message including list of devices mark and come true The fixed all of available idle channel of second equipment, the equipment mark that the list of devices mark for sending every time includes The quantity of knowledge can be less than or equal to the quantity of the RU that each channel includes, it is of course also possible to be more than every The quantity of the RU that individual channel includes.

Optionally, if quantity of the quantity of the second equipment more than the RU that each channel includes, first sets It is standby that the second equipment for collecting available idle channel can will be needed to be divided into K groups, the number of the second equipment in every group Quantity of the amount no more than the RU that each channel includes, is then identified by sending K including list of devices Channel resource message is collected to determine all of available idle channel of second equipment, each channel resource is received Collection message one group of second equipment of correspondence.Wherein, K >=2 and K are integer.

For example, the first equipment by channel resource configured information indicate the first channel resource for channel 1, Channel 2, channel 3, channel 4, each channel include 4 RU, respectively RU1, RU2, RU3, RU4.First equipment is it needs to be determined that the second equipment of available idle channel is respectively SAT1 (its equipment mark It is device identification 1 to know), SAT2 (its device identification be device identification 2), (its device identification is to set for SAT3 Standby mark is 3), SAT4 (its device identification is device identification 4), (its device identification is device identification to SAT5 5).First equipment can send two channel resources for including list of devices mark and collect message to determine to own The available idle channel of the second equipment.Equipment mark in the device identification list that first equipment sends for the first time The order of knowledge can be device identification 1, device identification 2, device identification 3.Now, device identification 1 can be with Corresponding with the RU1 in each channel, device identification 2 can be corresponding with the RU2 in each channel, equipment Mark 3 can be corresponding with the RU3 in each channel.SAT1, SAT2, SAT3 are respectively respective with it In corresponding RU available channel resources report message is sent to the first equipment.If channel 1, channel 2 for Available idle channel is for SAT1, SAT2, SAT3, then SAT1 can be at least one channel In RU1 on send available channel resources report message；SAT2 can be in the RU2 at least one channel Upper transmission available channel resources report message；SAT3 can send on the RU3 at least one channel can Use channel resource report message.Specifically, as shown in fig. 6, for a kind of channel that the embodiment of the present application is provided is provided Collect message transmission schematic diagram in source.Available channel resources are sent on the RU1 that SAT1 can be in each channel Report message；Available channel resources report message is sent on the RU2 that SAT2 can be in each channel； Available channel resources report message is sent on the RU3 that SAT3 can be in each channel.First equipment second The order of the device identification in the device identification list of secondary transmission can be device identification 4, device identification 5. Now, device identification 4 can be corresponding with the RU3 in each channel, and device identification 5 can be with each letter RU4 correspondences in road.If channel 3, channel 4 are available idle letter for SAT4, SAT5 Road, then SAT4 available channel resources report message can be sent on the RU3 at least one channel； SAT5 can send available channel resources report message on the RU4 at least one channel.Specifically, such as Shown in Fig. 6, SAT4 can send available channel resources report message on the RU3 in channel 3；SAT5 Available channel resources report message can be sent on the RU4 in channel 4.

Optionally, if quantity of the quantity of the second equipment more than the RU that each channel includes, first sets It is standby only to send a channel resource for including list of devices mark and collect message to determine all of the The available idle channel of two equipment, wherein, the list of devices mark that the first equipment sends includes all first Equipment is it needs to be determined that the mark of the second equipment of available idle channel.

Now, the 3rd channel resource is the time and frequency zone resource for including multiple RU and multiple time periods.It is described Device identification list indicates that the device identification of N in the device identification list can be with first The RU correspondences of M in each channel that channel resource includes.First equipment can be by the equipment Identification list indicate N in the device identification list device identification can with the T when Between section correspondence, or, the first equipment can also be indicated directly N in the device identification list Device identification can be corresponding with the T time period, so as to indicate to correspond to the second of the T time period set It is standby to send available channel resources report message in the T time period, wherein, T is positive integer.Citing For, N and M can meet following relation：M=N%A, wherein A are the RU that each channel includes Quantity, % is to take the remainder computing.

For example, N and T can meet following relation：WhereinIt is the fortune that rounds up Calculate.For example, each channel includes 4 RU, 5 device identifications are had in device identification list, according to Sequence of positions is respectively：Device identification 1, device identification 2, device identification 3, device identification 4, equipment mark Know 5.So, the time-domain resource of the corresponding transmission available channel resources report message of device identification 1 is：I.e. corresponding second equipment of device identification 1 can send available channel money in first time period Source report message；Device identification 5 it is corresponding send available channel resources report message time-domain resource be：I.e. corresponding second equipment of device identification 5 can send available channel money in second time period Source report message.

For example, with reference to the description of Fig. 7, the first equipment can also only send once includes list of devices mark The channel resource of knowledge collects message, and the list of devices mark for sending for the first time includes all it needs to be determined that available Idle channel the second equipment, wherein, the order of device identification is device identification 1, device identification 2, Device identification 3, device identification 4, device identification 5.First equipment directly indicates device identification 1, equipment Mark 2, the corresponding first time period T1 of device identification 3, when device identification 4, the correspondence of device identification 5 second Between section T2.Device identification 1 can be corresponding with the RU1 in each channel corresponding with first time period T1； Device identification 2 can be corresponding with the RU2 in each channel corresponding with first time period T1；Device identification 3 can be corresponding with the RU3 in each channel corresponding with first time period T1；Device identification 4 can be with RU4 correspondences in each channel are corresponding with second time period T2；Device identification 5 can be with each channel In RU1 correspondence it is corresponding with second time period T2.If channel 1, channel 2 for SAT1, SAT2, Available idle channel is for SAT3, if channel 3, channel 4 are equal for SAT4, SAT5 It is available idle channel.As shown in fig. 7, for a kind of channel resource collection that the embodiment of the present application is provided disappears Breath transmission schematic diagram.Send available in first time period T1, on the RU1 that SAT1 can be in each channel Channel resource report message；Send available channel resources report in each channel on the RU2 that SAT2 can be Message；Available channel resources report message is sent on the RU3 that SAT3 can be in each channel.Second Time period T2, SAT4 can send available channel resources report message on the RU3 in channel 3；SAT5 Available channel resources report message can be sent on the RU4 in channel 4.

If the 3rd channel resource is the frequency-code domain resource for including multiple RU and multiple orthogonal sequences.It is described to set Standby identification list indicates that the device identification of N in the device identification list can be with the first letter The RU correspondences of M in each channel that road resource includes, and the in the device identification list The device identification of N can be corresponding with k-th orthogonal sequence, i.e. N → (M, K), wherein, K is Positive integer.

For example, the first equipment by channel resource configured information indicate the first channel resource for channel 1, Channel 2, each channel includes 4 RU, respectively RU1, RU2, RU3, RU4.Meanwhile, each 4 orthogonal sequences, respectively P1, P2, P3, P4 are used in RU.First equipment is it needs to be determined that available Second equipment of idle channel is respectively SAT1 (its device identification is device identification 1), SAT2 (its equipment Be designated device identification 2), SAT3 (its device identification be device identification 3).The equipment that first equipment sends The order of the device identification in identification list is device identification 1, device identification 2, device identification 3.Equipment mark Knowing 1 can be corresponding with the RU2 in each channel corresponding with orthogonal sequence P1, i.e., device identification 1 → (RU2, P1)；Device identification 2 can be corresponding with the RU3 in each channel corresponding with orthogonal sequence P2, that is, set 2 → (RU3, P2) of standby mark；Device identification 3 can it is corresponding with the RU4 in each channel with it is orthogonal Sequence P3 correspondences, i.e. device identification 3 → (RU4, P3).Corresponding 3rd channel resources of SAT1 are every The set of the frequency indicated by (RU2, the P1)-code domain resource in individual channel；Corresponding 3rd channels of SAT2 Resource is the set of the frequency-code domain resource indicated by (RU3, P2) in each channel；SAT3 is corresponding 3rd channel resource is the set of the frequency-code domain resource indicated by (RU4, P3) in each channel.

Accordingly, in step 601, the channel resource that the second equipment can listen to the first device broadcasts is collected Message.

Step 602：Second equipment determines that second equipment is available from first channel resource Idle channel, and second channel resource is determined according to the available idle channel of the second equipment.

In step 602, the available idle channel of the second equipment can be to meet in following condition The channel of condition：

Second equipment determines according to CCA (Clear Channel Assessment, clear channel assessment (CCA)) It is idle channel；Or,

Wherein, CCA refers to that the second equipment is intercepted to channel, if intercepting the channel signal power more than pre- If threshold value, it is determined that the channel status of the channel is busy (busy)；Otherwise, it determines the channel shape of the channel State is idle (idle).

It should be noted that the definition of idle channel may finally be one of above three condition, will not be simultaneously Use two of which or more than two conditions.For example, standard may specify to determine to be needed simultaneously during idle channel Consider CCA and NAV, that is, use the 3rd condition.Therefore, " a condition in following condition is met " Refer to that condition for meeting standard regulation, rather than three kinds of conditions of satisfaction are said, any one is regarded as the free time Channel.

It should be noted that in step 601, if the channel resource that the second equipment is received is collected in message not Including device identification list, then the second equipment can directly perform step 602；What if the second equipment was received Channel resource collects message includes device identification list, and the second equipment is receiving the bag of the first equipment transmission Include device identification list channel resource collect message after, however, it is determined that the device identification of the second equipment be located at institute State in device identification list, then the first channel resource in message is collected according to the channel resource and determine second The available idle channel of equipment；If the second equipment determines that the device identification of the second equipment is not located at the equipment mark Know in list, then can ignore the channel resource collection message that first equipment sends.

Second equipment can have various ways to be determined for sending out according to the available idle channel of the second equipment The second channel resource of available channel resources report message, a kind of possible implementation is sent to be：Second equipment Randomly choose at least one frequency domain resource from the available idle channel of the second equipment, and according to it is described extremely A few frequency domain resource determines the second channel resource for sending the available channel resources report message.

For example, second channel resource is frequency domain resource.As shown in figure 8, for the embodiment of the present application is provided A kind of channel resource indicate schematic diagram.In Fig. 8, the first equipment is indicated by channel resource configured information First channel resource is channel 1, channel 2, channel 3, channel 4, and each channel includes 4 RU, point Wei not RU1, RU2, RU3, RU4.Second equipment determines that channel 1, channel 3 are available idle letter Road.Now, 8 RU are had and is available for the second equipment choice, the second equipment can be from channel 1, channel 3 At least one RU of middle random selection, and at least one RU is defined as the second channel resource. For example, the RU2 in the second equipment choice channel 1 is used as second channel resource.

Optionally, the second equipment randomly chooses a frequency domain money from the available idle channel of the second equipment Source.

For example, second channel resource is frequency domain resource.Second equipment is from the available sky of the second equipment A RU is randomly choosed in idle channel, and the RU is defined as the second channel resource.

It should be noted that the second equipment can in the following manner in any one from second equipment At least one frequency domain resource is randomly choosed in available idle channel.

Mode one, frequency domain keeps out of the way method：Second equipment randomly chooses one and keeps out of the way initial value A within the specific limits, According to the frequency order (or from low to high) from high to low of RU in available idle channel, A is selected Individual RU, and according to the A RU determine for send the available channel resources report message Two channel resources.

Mode two, p probabilistic methods：After second equipment receives channel resource collection message, determined with Probability p Respond the channel resource and collect message, being not responding to the channel resource with probability 1-p collects message.If Respond the channel resource and collect message, then determine second channel resource according to mode one.Wherein, Probability p Value can have distinct methods, such as in 802.11 standards predefine, or according to receive channel resource receive Collection message determination etc..

Mode three, time domain keeps out of the way method：Second equipment randomly chooses one and keeps out of the way initial value B within the specific limits, Then often receive channel resource and collect message, will just keep out of the way initial value B and subtract 1, when keeping out of the way initial value B For 0 when, pass-through mode one or mode two determine second channel resource.

Alternatively possible implementation is：Second equipment is according to the device identification list or described Channel resource mapping indication information determines the 3rd channel resource corresponding with second equipment；Described second sets It is standby to determine that at least one is corresponding with the 3rd channel resource from the available idle channel of the second equipment Frequency domain resource；Second equipment is according to described at least one frequency domain corresponding with the 3rd channel resource Resource determines the second channel for sending available channel resources report message from the 3rd channel resource Resource.

If second channel resource and the 3rd channel resource are frequency domain resource.Second equipment is according to Device identification list or the channel resource mapping indication information determine corresponding with second equipment the Three channel resources；Second equipment determine from the available idle channel of the second equipment at least one with The corresponding RU of 3rd channel resource, second equipment will be determined and the 3rd channel resource Corresponding at least one RU is defined as the second channel resource for sending available channel resources report message. It should be noted that now corresponding with the 3rd channel resource in the available idle channel of the second equipment RU, be that included RU in the available idle channel of the second equipment is corresponding with second equipment The 3rd channel resource in included RU common factor.

Optionally, the second equipment is provided according to from the available idle channel of the second equipment and the 3rd channel A randomly selected RU determines second channel resource in the corresponding RU in source, or, second equipment Determined according to all RUs corresponding with the 3rd channel resource in the available idle channel of the second equipment Second channel resource.

For example, second channel resource and the 3rd channel resource are frequency domain resource.First equipment passes through Channel resource configured information indicates the first channel resource for channel 1, channel 2, channel 3, channel 4, often Individual channel includes 4 RU, respectively RU1, RU2, RU3, RU4.First equipment is it needs to be determined that can Second equipment of idle channel is respectively SAT1 (its device identification is device identification 1), SAT2 (its Device identification is device identification 2).The order of device identification in the device identification list that first equipment sends is Device identification 1, device identification 2.Now, device identification 1 can be corresponding with the RU2 in each channel, Device identification 2 can be corresponding with the RU3 in each channel.Corresponding 3rd channel resources of SAT1 are each The set of the RU2 in channel；Corresponding 3rd channel resources of SAT2 are the set of the RU3 in each channel. SAT1 determines channel 1, channel 3 for available idle channel, and channel 2, channel 4 are busy channel；SAT2 Channel 3, channel 4 are determined for available idle channel, and channel 1, channel 2 are busy channel.SAT1 determines Frequency domain resource corresponding with the 3rd channel resource is the RU2 in channel 1 in available idle channel, and will letter RU2 in road 1 is defined as the second channel resource for sending available channel resources report message.SAT2 Frequency domain resource corresponding with the 3rd channel resource is the RU3 in channel 3 in determining available idle channel, and RU3 in channel 3 is defined as the second channel resource for sending available channel resources report message.

In above-mentioned example, with the 3rd letter in the frequency domain resource that SAT1 can also include available idle channel The frequency domain resource that resource corresponding all frequency domain resources in road are defined as, that is, determine corresponding with the 3rd channel resource Frequency domain resource be RU2, the RU2 in channel 3 in channel 1, and by the RU2 in channel 1, letter RU2 in road 3 is defined as the second channel resource for sending available channel resources report message.SAT2 All frequency domains corresponding with the 3rd channel resource in the frequency domain resource that available idle channel can also be included The frequency domain resource that resource is defined as, that is, determine frequency domain resource corresponding with the 3rd channel resource in channel 3 RU3, channel 4 in RU3, and by the RU3 in channel 3, the RU3 in channel 4 be defined as use In the second channel resource for sending available channel resources report message.

If second channel resource and the 3rd channel resource are frequency-code domain resource.Second equipment according to The device identification list or the channel resource mapping indication information determine corresponding with second equipment The 3rd channel resource；Second equipment determines at least one with described from the 3rd channel resource The corresponding frequency of the available idle channel of two equipment-code domain resource；Second equipment by described at least one frequency- Code domain resource is defined as the second channel resource for sending available channel resources report message.3rd channel is provided Element in the correspondence set of source is frequency-code domain resource, and the element in idle channel correspondence set is channel, institute Meaning determines frequency-code domain resource corresponding with available free channel from the 3rd channel resource, refers to for the free time Each channel in channel set, finds out from frequency domain positioned at the channel from the 3rd channel resource set In frequency-code domain Resource Block, i.e. the corresponding frequency of the channel-code domain Resource Block.Owned by idle channel set The corresponding frequency of channel-code domain Resource Block constitutes a frequency-code domain resource collection, from the set selected section or All frequency-code domain Resource Block constitutes a subset, and the subset is second channel resource.

For example, the first equipment by channel resource configured information indicate the first channel resource for channel 1, Channel 2, each channel includes 4 RU, respectively RU1, RU2, RU3, RU4.Meanwhile, it is orthogonal Sequence list includes 4 orthogonal sequences, respectively P1, P2, P3, P4.First equipment it needs to be determined that Second equipment of available idle channel is respectively SAT1 (its device identification is device identification 1), SAT2 (its Device identification is device identification 2).The order of device identification in the device identification list that first equipment sends is Device identification 1, device identification 2.Device identification 1 can it is corresponding with the RU2 in each channel with it is orthogonal Sequence P1 correspondences；Device identification 2 can and orthogonal sequence P2 pair corresponding with the RU3 in each channel Should.Corresponding 3rd channel resources of SAT1 are the frequency-code domain indicated by (RU2, P1) in each channel The set of resource；Corresponding 3rd channel resources of SAT2 are that (RU3, P2) in each channel is indicated Frequency-code domain resource set.If STA1 determines that channel 1 is available idle channel with channel 2, RU corresponding with the 3rd channel resource is RU2, the channel in channel 1 in the available idle channels of STA1 RU2 in 2, such that it is able to from (RU2, the P1) in channel 1, in (RU2, the P1) in channel 2 Random selection at least one frequency-code domain resource be defined as send available channel resources report message second Channel resource；STA2 determines channel 2 for available idle channel, then in the available idle channels of STA2 RU corresponding with the 3rd channel resource be channel 2 in RU3, such that it is able to from channel 2 (RU2, P1 at least one frequency-code domain resource of random selection is defined as sending available channel resources report message in) Second channel resource.

It should be noted that for how to indicate frequency-code resource not limit in the embodiment of the present application, can be with Each frequency-code resource is numbered, frequency-code resource, example are indicated by the corresponding label of each frequency-code resource Such as, include 4 RU in a channel, totally 4 orthogonal sequences, then signal include altogether 16 frequencies- Code domain resource, can be numbered with 1 to 16 to each frequency-code domain resource；Can also be with (channel is compiled Number, RU numberings, orthogonal sequence numbering) indicate a frequency-code resource；Can also use (channel number, Frequently-code domain resource number) indicate a frequency-code resource.

In such scheme, because the second equipment is determined for sending out according to the available idle channel of the second equipment Send the second channel resource of available channel resources report message, therefore second setting of being proposed of the embodiment of the present application The standby process for determining available idle channel can't bring extra interference to OBSS in itself.

Step 603：Second equipment sends described by the second channel resource to first equipment Available channel resources report message, the available channel resources report message indicates that second equipment can use Idle channel.

In step 603, the available channel resources report message can indicate described by two ways The available idle channel of two equipment.Discuss separately below.

First way：The available channel resources report message is by the available channel resources report message The idle channel list for including indicates the available idle channel of the second equipment.

In the embodiment of the present application, the idle channel list can be used as including the second equipment available free time The list of the channel logo of channel.

For example, the second equipment can generate an idle letter for the channel logo for including available idle channel Road list, and the idle channel list is sent to the first equipment by available channel resources report message, from And indicate the available idle channel of the second equipment.

The idle channel list can also be channel status bit map, the channel resource status bits Scheme the channel status for characterizing each channel that first channel resource includes, the channel status is It is idle or busy.For example, certain bit is set to the corresponding letter of the 1 expression bit in channel status bit map Road is idle, i.e., the channel can use, and is set to the corresponding channel busy of the 0 expression bit, i.e. channel is unavailable.The It is that busy channel sends available channel resources report message that two equipment will not be gone using channel status.

For example, the first equipment by channel resource configured information indicate the first channel resource for channel 1, Channel 2, channel 3, channel 4, channel 5, channel 6.Second equipment determines that available idle channel is letter Road 1, channel 2, channel 5, it is determined that the channel status bit map for going out can be 110010, wherein 1 Idle channel is represented, 0 represents busy channel.It is of course also possible to represent idle channel with 0,1 represents busy letter Road, the channel status bit map now determined can be 001101.

It should be noted that when the idle channel list is channel status bit map, the first equipment and the Two equipment need to make an appointment the corresponding channel of each bit in channel status bit map.The mode of agreement has It is various, for example, the first equipment is when channel resource collection message is sent, in channel resource collects message about Determine the corresponding channel of each bit in channel status bit map.Specifically, can be indicated with implicit. For example, the first channel resource that the channel resource that the first equipment sends is collected in message indicates 80MHz channels, The then idle channel list of the second equipment is 4 bit channel status bits bitmaps, wherein 4 bits are corresponded to respectively Four of (or from low to high) from high to low in 80MHz channel frequency domains indicated by first channel resource 20MHz channels.

If it should be noted that the available channel resources report message that the second equipment sends includes idle letter Road list, the second equipment can only select a RU as transmission available channel from available idle channel The second channel resource of resource report message.

The second way：The available channel resources report message is reported by carrying the available channel resources The corresponding channel of second channel resource of message indicates the available idle channel of the second equipment.

If specifically, the second channel resource for carrying the available channel resources report message is to include multiple The frequency domain resource of RU, then the corresponding channels of each RU can set as described second in second channel resource Standby available idle channel.So-called " the corresponding channels of RU ", refers to the channel where the RU.Existing mark In standard, the bandwidth of the channel where RU is typically 20MHz channels.

If the second channel resource for carrying the available channel resources report message is to include multiple RU and just Frequency-code domain the resource of sequence is handed over, then each corresponding channel of frequency-code domain resource can be made in second channel resource It is the available idle channel of the second equipment.So-called " the corresponding channel of frequency-code domain resource " refers to frequently- 20MHz channels where code domain resource.Frequently-code domain resource can be characterized with (RU, orthogonal sequence), Therefore so-called " the corresponding channel of frequency-code domain resource " is where it is also assumed that be the RU in frequency-code domain resource 20MHz channels

For example, second channel resource is the frequency domain resource for including multiple RU, it is many that second channel resource includes Individual RU is RU corresponding with second equipment in the second equipment each available idle channel.Second sets It is standby that available channel resources report message is sent by the second channel resource, so as to indicate and described second The available idle channel of equipment.Again for example, second channel resource is to include multiple RU and with described second The frequency of the corresponding orthogonal sequence of equipment-code domain resource, multiple RU that second channel resource includes are the second equipment RU corresponding with second equipment in each available idle channel.Second equipment is in second channel resource Including each RU in using orthogonal sequence corresponding with second equipment send available channel resources report Message, so as to indicate and the available idle channel of the second equipment.

In this mode, idle letter can not be included in the available channel resources report message that the second equipment sends Road list.

Optionally, buffer status can also be included in the available channel resources report message that the second equipment sends (buffer status) information, the buffer status information is used for the number for indicating second equipment to need transmission According to data volume, or time required for second equipment transmission data.

Step 502：First equipment receives second equipment by can use that second channel resource sends Channel resource report message, the available channel resources report message indicates the available sky of the second equipment Idle channel；The available idle channel of second equipment is second equipment from first channel resource Determine, the second channel resource is that second equipment determines according to the idle channel.

In step 502, first equipment can will carry the second of the available channel resources report message The corresponding channel of channel resource is defined as the available idle channel of the second equipment.

For example, the first equipment indicates 4 channels and can use, respectively channel 1, channel 2, Channel 3, channel 4.Each channel includes 4 RU, respectively RU1, RU2, RU3, RU4.The One equipment received on the RU1 of channel 1 the available channel resources report message that second equipment sends, The available channel resources report message that second equipment sends is received on the RU1 of channel 3, then first Channel 1, channel 3 can be defined as the available idle channel of the second equipment by equipment.

Described in the idle channel list determination that first equipment can also be in available channel resources report message The available idle channel of second equipment.

For example, the first equipment determines that the idle channel list that receives includes channel 1, channel 3 Channel logo, then can determine that channel 1, channel 3 are the available idle channel of the second equipment.

For example, the first equipment indicates 4 channels and can use, respectively channel 1, channel 2, Channel 3, channel 4.First equipment determines that the idle channel list for receiving can be 1010, then first set It is standby to determine channel 1, channel 3 for the available idle channel of the second equipment, wherein 1 represents idle channel, 0 represents busy channel.

First equipment can also determine second according to the buffer status information in available channel resources report message Equipment needs the data volume of the data of transmission, or the time required for second equipment transmission data.

First equipment determines the second equipment available free time according to the available channel resources report message for receiving After channel, the UL MU scheduling triggering equipment of frame scheduling second can be sent in the second equipment available free time UL MU transmission is carried out on channel so that the scheduling that the second equipment can timely respond to the transmission of the first equipment is touched Hair frame, so as to improve channel utilization.

Optionally, the first equipment according to the available idle channel of the second equipment to the second equipment scheduling UL MU Before transmission, second equipment that can also dispatch send NDP Sounding (Null Data Packet Sounding, Zero data message is detected) message, to measure the uplink channel of the second equipment, so as to ensure follow-up UL MU The configured transmission of each the second equipment, such as resource allocation and MCS can be accurately specified during scheduling (Modulation and Coding Scheme, modulation and encoding scheme) etc..

In the embodiment of the present application, because the first equipment has determined that the available idle channel of the second equipment, because This can accurately dispatch each second equipment and send the channel that NDP Sounding are used, and multiple second sets NDP Sounding can be just sent by the way of frequency division multiplexing between standby, is opened so as to save time-domain transmission Pin.For example, as shown in figure 9, for the second equipment of a kind of scheduling that the embodiment of the present application is provided sends NDP Sounding schematic diagrames.Fig. 9 includes 4 the second equipment, respectively STA1, STA2, STA3, STA4.Having 4 channels can use, respectively channel 1, channel 2, channel 3, channel 4.First sets It is respectively for each available idle channel of the second equipment is determined：The available idle channels of STA1 are channel 1st, channel 4；The available idle channels of STA2 are channel 2, channel 3；The available idle channels of STA3 are Channel 1, channel 2；The available idle channels of STA4 are channel 3, channel 4.Now, the first equipment can To send the measurement notification message (Trigger frame for Sounding, TF-S) that triggering up channel is measured, STA1, STA2 scheduling are sent into NDP Sounding in the same time, STA3, STA4 scheduling are existed The same time sends NDP Sounding, so as to improve channel utilization.

Process above is described below by specific embodiment.

As shown in Figure 10, it is a kind of channel resource indicating means schematic flow sheet that the embodiment of the present application is provided.

Figure 10 includes that two the second equipment are respectively：STA1 and STA2.
