Or, the frequency domain resource frequency spectrum of 80MHz bandwidth can be made up of the frequency domain resource block in layer 6, in this case, the frequency domain resource of the 80MHz bandwidth distributes to a website, and it is possible to transmit the situation that indication bit indicates resource allocation by the bandwidth configured information in lead code and single user.It should be understood that being analogous to above-mentioned frequency spectrum profile, 160MHz etc. is extended also to.

It should be understood that, resource allocation is divided into two kinds, one kind is centralized resources distribution method, the frequency domain resource distribution for distributing all websites is indicated to concentrate in a configured information (set that frequency domain resource distribution is indicated), and identification information of station is concentrated in a configured information (set of identification information of station).Another is the distributed resource allocation method based on each website, that is, the frequency spectrum resource distribution for distributing the website indicates to be distributed in the site parameter information of each website with identification information of station.Described in Fig. 6-Figure 14 it is hereinafter the centralized resources distribution method of the first.Described in Figure 15 for another distributed resource allocation method based on each website.

Fig. 6 is the indicative flowchart of the method for the resource allocation of one embodiment of the invention.Method shown in Fig. 6 can be performed by sending ending equipment, and sending ending equipment can be access point, or website.Method shown in Fig. 6 includes：

610, sending ending equipment determines the resource indication information for carrying out resource allocation in time domain and frequency domain, resource indication information includes persond eixis information and the first configured information for carrying out resource allocation on frequency domain, wherein, persond eixis information be included in time domain carry out resource allocation period number or persond eixis information be included in time domain carry out resource allocation period number and time segment length；

620, resource indication information is sent to receiving device, in order to which receiving device determines the running time-frequency resource of distribution according to resource indication information.

In the embodiment of the present invention, sending ending equipment sends the configured information for carrying out resource allocation on frequency domain and the persond eixis information for carrying out resource allocation in time domain to receiving terminal.So, the embodiment of the present invention indicates resource allocation in two dimensions of frequency and time, realizes and running time-frequency resource is distributed in time domain and frequency domain, i.e., carry out resource division using frequency division multiplexing and time division multiplexing simultaneously.

It should be understood that the first configured information can be used for carrying out resource allocation on frequency domain.First configured information can be the resource indication information in the resource allocation methods of existing use frequency division multiplexing, you can think the partial information in HE-SIGB.If the method distributed based on the first above-mentioned centralized resources, the first configured information can include frequency domain resource distribution configured information, identification information of station and the site parameter information for indicating that frequency range is divided.In addition, the Cyclic Redundancy Code for the tail bit of convolutional encoding and for error detection can also be included in efficient signaling field B.

The embodiment of the present invention can add persond eixis information in publicly-owned parameter information.As one embodiment, if the number of kilo byte instruction time section can be increased in publicly-owned parameter information.For example, 1 bit of addition, the instruction for realizing most 2 periods；In another example, add 2 bits, the instruction for realizing most 4 periods.Alternatively, persond eixis information can also be placed on other positions in HE-SIG-B, and the embodiment of the present invention is not limited.

Alternatively, as one embodiment, the period that resource allocation is carried out in time domain is isometric, and persond eixis information is only included in the period number that resource allocation is carried out in time domain, wherein, the length of each period is indicated according to period number recessiveness.

Specifically, the time segment length divided in some scheduling can be with identical.Now, persond eixis information can only include period number, and time segment length can be with implicit representation.Each isometric time segment length can be indicated according to period number and data field total length come recessive.Data field total length can be the summation of all data fields in time division multiplexing PPDU, and the data field total length can pass through The length that length field in L-SIG is indicated subtracts HE-SIG-A, and HE-SIF-B is calculated with HE-STF the and HE-LTF length before each data field.When the aliquant period number of data field total length, the time segment length that the length of last period can be more isometric than other is small.Alternatively, as another embodiment, persond eixis information when time segment length is identical can also include period number and time segment length.Wherein, time segment length can be one kind, that is, indicate the length of isometric period.Time segment length can also be two kinds, that is, indicate the length of isometric period and the length of last period.

Alternatively, as another embodiment, the time segment length divided in some scheduling can be different.Specifically, persond eixis information can include period number and time segment length.The time segment length can be corresponded with period number.For example, it is 4 that 4 periods, i.e. period number are divided into some scheduling, then time segment length can be 4 values, indicate respectively the length of each period.

Alternatively, as another embodiment, persond eixis information also includes broadcast frame configured information, and broadcast frame configured information is used for the period for indicating to send broadcast frame.

Specifically, broadcast frame configured information can indicate which is used for sending broadcast frame (such as multicast frame) period.Alternatively, as one embodiment, the period number that some scheduling is divided is 4, for indicating that the broadcast frame configured information of multicast frame can be " 1010 ", it is broadcast frame then to represent the 1st period and the 3rd period, and the 2nd period and the 4th period are normal data frame.

Alternatively, as another embodiment, when broadcast frame (such as multicast frame) is only being sent the 1st period, the broadcast frame configured information can also indicate whether first time period sends broadcast frame with 1 bit.For example period number is 4, and broadcast frame configured information can be " 1 ", then it represents that the 1st period is broadcast frame (multicast frame), and other 3 periods are normal data frame.Broadcast frame configured information can be " 0 ", then it represents that 4 periods are normal data frame.

Alternatively, as another embodiment, when broadcast frame (such as multicast frame) is only being sent last 1 period, the broadcast frame configured information can also indicate whether first time period sends broadcast frame with 1 bit.For example period number is 4, and broadcast frame configured information can be " 1 ", then it represents that last 1 period is broadcast frame (multicast frame), and other 3 periods are normal data frame.Broadcast frame configured information can be " 0 ", then it represents that 4 periods are normal data frame.

It should be understood that the period of the embodiment description in the embodiment of the present invention involved by the schematic diagram of the time-frequency resource allocating based on Fig. 7, Figure 12 and Figure 13 does not include the period for sending broadcast frame for normal data frame corresponding period, i.e. period described in embodiment.As one embodiment, the period number for sending broadcast frame can be one.For example, the period number that certain scheduling is divided is 4, broadcast frame refers to Show that the bit of information is designated as " 1000 ", represent that first period is used for sending broadcast frame, other three periods are normal data frame.So, the description based on Fig. 7, Figure 12 and Figure 13 pertains only to remove other 3 periods of first period in the embodiment of the present invention, is then based on resource in this 3 periods discussion temporal frequencies and indicates.The embodiment of the present invention can also send broadcast frame in last period, i.e. the bit of broadcast frame configured information is designated as " 0001 ".It should be understood that the embodiment of the present invention is not limited for sending the period of broadcast frame.Alternatively, as another embodiment, the period number for sending broadcast frame can also be multiple.For example, the period number that certain scheduling is divided is 6, the bit of broadcast frame configured information is designated as " 101000 ", represents that first period and the 3rd period are used for sending broadcast frame, other four periods are normal data frame.So, Fig. 7 is based in the embodiment of the present invention, Figure 12, Figure 13 embodiment only has 4 periods, being then based on this 4 periods discusses that resource is indicated in its temporal frequency.It should also be understood that the embodiment for normal data frame is described, remaining 4 periods are considered as adjacent between any two, i.e., the 2nd period and the 4th period in 6 periods are adjacent.

Persond eixis information can also be indicated and time migration amount instruction by including time starting point in each site parameter information.But, the overhead bit of this method is larger.In the agreement that existing 802.11ax has reached, one OFDM (Orthogonal Frequency Division Multiplexing, OFDM) data symbol length is 12.8us, it is assumed that competing cycle length is 0.8us, then the OFDM symbol length is 13.6us.The maximum transmitted chance occupied of one access point is 5.484ms, if persond eixis is in units of 8 OFDM symbols, so 5.484ms/ (13.6*8) us=51 OFDM symbol, that is to say, that time starting point and time offset respectively need 6 (log (51)) bits to indicate.9 websites can be at most called under 20MHz bandwidth, then need 108 bits to indicate altogether.For bigger bandwidth (40/80/160MHz), if can at most dispatch 16 websites, then need 192 bits to indicate altogether.Therefore, this embodiment is needed for the resource allocation in the independent instruction time of each website, and overhead bit is larger.

As one embodiment, the resource indication information in the embodiment of the present invention can include the first configured information and persond eixis information.Within the period once dispatched, the first configured information can include frequency domain resource distribution configured information, identification information of station and site parameter information.Wherein, the frequency domain resource distribution configured information of multiple periods may be constructed frequency domain resource distribution configured information set, multiple identification information of station may be constructed identification information of station set, and site parameter information can include site parameter information of site parameter information, the site parameter information of the second website and the 3rd website of the first website etc..

Wherein, frequency domain resource distribution configured information can be corresponding frequency spectrum dividing condition of each period. Can be as follows for the description that frequency domain resource distributes configured information：Frequency domain resource distribution configured information is used to indicate that frequency range is divided.Specifically, there is a corresponding frequency domain resource distribution configured information each period in frequency range, and multiple periods corresponding multiple frequency domain resources distribution configured informations constitute frequency domain resource distribution and indicate set.The form that the embodiment of the present invention distributes configured information to frequency domain resource is not limited.For example, frequency domain resource distribution configured information can indicate for bitmap (bitmap), i.e., represent to distribute to the resource block of same website with continuous " 1 (0) " sequence, use 1->0 or 0->1 transformation represents to be switched to another website.The schematic diagram of time-frequency resource allocating as shown in Figure 7, it can be 001101100 in the period 1 that the frequency domain resource for using this method to obtain, which distributes configured information, can be 001101111 in the period 2.It should be understood that this method can from top to bottom be read from Fig. 7 longitudinal axis, it can also read from lower to upper.

Specifically, if by taking the schematic diagram of time-frequency resource allocating hereinafter shown in Fig. 7 as an example, indicating to distribute configured information as frequency domain resource using the bitmap (bitmap) in above-mentioned example, then frequency domain resource distribution configured information can be：001101100 001101111, identification information of station set can be：AID1 AID2 AID3 AID4 AID5 AID1 AID6 AID7 AID8.

Therefore, the embodiment of the present invention is avoided as the resource allocation in the independent instruction time of each website, can save overhead bit.

Alternatively, it is used as another embodiment, first configured information can include identification information of station, wherein, resource indication information can also include site identity duplicate message, and site identity duplicate message is used to indicate whether the identification information of station that the first frequency range is distributed in the first frequency range is distributed in current slot identification information of station and time adjacent segments is identical.

It should be understood that identification information of station can be the identification information of some website.Identification information of station set in each embodiment can be understood as the set of the identification information of station of multiple websites.It will also be understood that, site identity duplicate message is used to indicate whether whether the identification information of station of some resource block identical with the identification information of station of the Adjacent resource block of time adjacent segments, and the set of site identity duplicate message can include the set of the corresponding site identity duplicate message of each identification information of station.

In addition, can also identify duplicate message to indicate whether the identification information of station that the identification information of station that a certain resource block is distributed in the current slot resource block adjacent with the resource block in time adjacent segments is distributed is identical to receiving device transmitting station in the embodiment of the present invention.So, the embodiment of the present invention can be with Clipped identification information of station, further saves overhead bit.

Fig. 7 is the schematic diagram of the time-frequency resource allocating of one embodiment of the invention.Fig. 8 is the schematic diagram of the resource indication information of one embodiment of the invention.The resource indication information of one embodiment of the invention is described below in conjunction with Fig. 7 and Fig. 8.

Site identity duplicate message is the corresponding first site identity duplicate message of the first identification information of station, and the first site identity duplicate message is 1 bit information and is attached to after the first identification information of station.

Site identity duplicate message can indicate whether the first frequency range is distributed in current slot identification information of station is identical with the identification information of station that first frequency range in previous time period is distributed, and can also indicate that whether the identification information of station that the first frequency range is distributed in current slot is identical with the identification information of station that interior first frequency range of latter time period is distributed.That is, the indicating means of identification information of station can include above two.

Assuming that the identification information of station that each resource block is inserted is as shown in fig. 7, simple in order to describe, identification information of station can be represented with AIDn, and wherein n is sequence number.Each identification information of station can be represented with 11 bit datas.As shown in fig. 7, the identification information of station that first resource block on the period 1 is inserted is AID5, the identification information of station that the 3rd resource block is inserted is AID3, and the identification information of station that the 5th resource block is inserted is AID1.From figure 7 it can be seen that the identification information of station that the resource block of period is inserted has overlapping, and identification information of station generally requires 11 bit datas and represented, overhead bit is than larger.The embodiment of the present invention can indicate whether the identification information of station that first frequency range is distributed in identification information of station and time adjacent segments that the frequency range of current slot first distributed is identical by 1 bit information of affix after each identification information of station.So, the embodiment of the present invention can avoid the identification information of station for indicating to repeat, and save overhead bit.

Forward direction is contrasted：Method one, site identity duplicate message can indicate whether the first frequency range is distributed in current slot identification information of station is identical with the identification information of station that first frequency range in previous time period is distributed.

Specifically, when first site identity duplicate message of 1 bit information added after the first identification information of station is 1, it can represent that the identification information of station that the frequency range of current slot first is distributed is identical with the identification information of station that the frequency range of previous time period first is distributed；When the first site identity duplicate message is 0, it can represent that the identification information of station that the frequency range of current slot first is distributed is different from the identification information of station that the frequency range of previous time period first is distributed.It should be understood that the first frequency range can be any frequency range in whole frequency band, the identification information of station that the first identification information of station can be distributed for any one resource block.

1 bit information added after identification information of station on first period can be defaulted as 0. Include identical identification information of station due to the forward direction comparison method using method one and on second period, in order to save the identification information of station of repetition, therefore the identification information of station and corresponding site identity duplicate message repeated on first period can be omitted.For example, by taking Fig. 5 as an example, identification information of station (STA ID)+site identity duplicate message (can be represented with repeat bits) on first period can be：The AID5 0 of 0 AID3 of AID2,0 AID4 0, the STA ID+repeat bits on second period can be the AID8 0 of 1 AID6 of AID1,0 AID7 0.

Backward contrast：Method two, site identity duplicate message can also indicate that whether the identification information of station that the first frequency range is distributed in current slot is identical with the identification information of station that first frequency range in latter time period is distributed.

Specifically, when first site identity duplicate message of 1 bit information added after the first identification information of station is 1, it can represent that the identification information of station that the frequency range of current slot first is distributed is identical with the identification information of station that the frequency range of latter time period first is distributed；When the first site identity duplicate message is 0, it can represent that the identification information of station that the frequency range of current slot first is distributed is different from the identification information of station that the frequency range of latter time period first is distributed.It should be understood that the first frequency range can be any frequency range in whole frequency band, any one identification information of station in all identification information of station that the first identification information of station can distribute for all resource blocks.

1 bit information added after identification information of station on last period can be defaulted as 0.By taking Fig. 7 as an example, include identical identification information of station due to the backward comparison method using method two and on second period, in order to save the identification information of station of repetition, therefore omitted by the identification information of station and corresponding site identity duplicate message that are repeated on second period.For example, by taking Fig. 7 as an example, identification information of station (STA ID)+site identity duplicate message (can be represented with repeat bits) on first period can be：The AID5 0 of 0 AID4 of AID1 1 AID2,0 AID3 0, the STA ID+repeat bits on second period can be the AID8 0 of 0 AID7 of AID6 0.

In above two method, resource indication information can be summarized as the resource indication information shown in Fig. 8, i.e., the resource indication information shown in Fig. 8 can include the site parameter information (can be represented with STA Parameters) of frequency resource allocation configured information set (can be represented with Frequency Resource Allocation List), (identification information of station+site identity duplicate message) set and each website.Site parameter information can include site parameter information, site parameter information of the second website of the first website etc..Publicly-owned parameter information can also be included in resource indication information.Wherein, the site parameter information of the first website can include modulation and coding strategy (Modulation and Coding Scheme, MCS), flow number (Number of Streams, Nsts), type of coding (coding type), transmission beam shaping (Transmit Beamforming, TxBF) or space-time block code (Space Time Block Code, STBC) etc..

Alternatively, as another embodiment, the corresponding second site identity duplicate message of identification information of station that site identity duplicate message is distributed by first time period, the second site identity duplicate message is at least one bit information.

Specifically, if the number for the identification information of station that certain time period (i.e. first time period) is distributed is at least one, the second site identity duplicate message is corresponding at least one bit information.First time period can be any time period, then the second site identity duplicate message is the corresponding site identity duplicate message of any time period.For example, five resource blocks of certain time period are assigned with 5 identification information of station, then the second site identity duplicate message is 5 bit informations.Site identity duplicate message collection is combined into the set of multiple second site identity duplicate messages.

It should be understood that the site identity duplicate message of Fig. 8 descriptions is 1 bit information, the site identity duplicate message can be attached to after identification information of station.When site identity duplicate message represents the corresponding second site identity duplicate message of identification information of station that certain time period is distributed, second site identity duplicate message is at least one bit information, and the second site identity duplicate message now, which can not be attached to after other information, individually to be deposited.Distributed for example, the site identity duplicate message set being made up of corresponding multiple second site identity duplicate messages of multiple periods can be located at frequency domain resource between configured information set and identification information of station set.The embodiment can be as shown in Figure 9.Fig. 9 is the schematic diagram of the resource indication information of another embodiment of the present invention.

Resource indication information shown in Fig. 9 can include the site parameter information (can be represented with STA Parameters) of the set of frequency resource allocation configured information, identification information of station set, the set of site identity duplicate message and each website.The site parameter information of each website can include site parameter information, site parameter information of the second website of the first website etc..Resource indication information shown in Fig. 7 can also include publicly-owned parameter information.The site parameter information of first website therein can include modulation and coding strategy (Modulation and Coding Scheme, MCS), flow number (Number of Streams, Nsts), type of coding (coding type), transmission beam shapes (Transmit Beamforming, TxBF) or space-time block code (Space Time Block Code, STBC) etc..

In fig .9, the corresponding site identity duplicate message of each identification information of station can individually be extracted and is distributed positioned at frequency domain resource between configured information set and identification information of station set.Corresponding to two kinds of control methods of above-mentioned forward and backward, with reference to Fig. 7 and Fig. 9, resource indication information can be shown as：

Method one '：Site identity duplicate message collection is combined into 0,000 1000, and identification information of station collection is combined into STA2 STA3 STA4 STA5 STA1 STA6 STA7 STA8。

In method one ', there can also be another embodiment.The set of site identity duplicate message can be 00,000 1000, and identification information of station set can be STA1 STA2 STA3 STA4 STA5 STA6 STA7 STA8.To sum up, two kinds of embodiments in method one can avoid the identification information of station repeated, save overhead bit.

Method two '：Site identity duplicate message collection is combined into 10,000 000, and identification information of station collection is combined into STA1 STA2 STA3 STA4 STA5 STA6 STA7 STA8.

Alternatively, as another embodiment, the first configured information includes the frequency domain resource distribution configured information for being used to indicate that frequency range is divided, and the second site identity duplicate message is attached to after frequency domain resource distribution configured information.

Specifically, second site identity duplicate message can be respectively attached to according to the division of period after corresponding frequency domain resource distribution configured information, the frequency domain resource distribution configured information of all periods and the second site identity duplicate message have collectively constituted set, i.e. (frequency domain resource distributes configured information+site identity duplicate message) set.The embodiment can be as shown in Figure 10.Figure 10 is the schematic diagram of the resource indication information of another embodiment of the present invention.Resource indication information shown in Figure 10 can include the site parameter information (can be represented with STA Parameters) of (frequency resource allocation configured information+site identity duplicate message) set, identification information of station set and each website.The site parameter information of each website can include site parameter information, site parameter information of the second website of the first website etc..Resource indication information shown in Figure 10 can also include publicly-owned parameter information.The site parameter information of first website therein can include modulation and coding strategy (Modulation and Coding Scheme, MCS), flow number (Number of Streams, Nsts), type of coding (coding type), transmission beam shapes (Transmit Beamforming, TxBF) or space-time block code (Space Time Block Code, STBC) etc..

In Fig. 10, the embodiment of the present invention can extract the corresponding site identity duplicate message of the identification information of station in each period respectively, and be attached to after the frequency domain resource of corresponding period distribution configured information.Corresponding to two kinds of control methods of above-mentioned forward and backward, with reference to Fig. 7 and Figure 10, resource indication information can be shown as：

Method one "：Frequency domain resource distribution on first period is designated as 001101100, and additional corresponding second site identity duplicate message is 0000, and identification information of station collection is combined into the AID4 AID5 of AID2 AID 3.Frequency domain resource distribution on second period is designated as 001101111, and additional corresponding second site identity duplicate message is 1000, and identification information of station collection is combined into AID1 AID6 AID7 AID8. (frequency domain resource distributes configured information+site identity duplicate message) collection is combined into：001101100 0000 001101111 1000.

In method one ", other embodiment can also be included.Frequency domain resource distribution configured information on first period is 001101100, and additional corresponding second site identity duplicate message is 00000, and corresponding multiple identification information of station are the AID4 AID5 of AID1 AID2 AID 3.Frequency domain resource distribution configured information on second period is 001101111, and additional corresponding second site identity duplicate message is 1000, and corresponding multiple identification information of station are AID6 AID7 AID8.(frequency domain resource distributes configured information+site identity duplicate message) collection is combined into：001101100 00000 001101111 1000.This embodiment can also omit the overhead bit of identification information of station.

Figure 11 is the indicative flowchart of the method for the resource allocation of another embodiment of the present invention.The step identical with Fig. 6 can be using being identically numbered in Fig. 9, and before 620, the method shown in Figure 11 also includes：

630, operation is compressed to site identity duplicate message set, the set of site identity duplicate message includes the corresponding site identity duplicate message of identification information of station that all resource blocks are distributed.

In addition, after being compressed to site identity duplicate message set, can further save overhead bit.

It should be understood that can also be without squeeze operation in the embodiment of the present invention, but eliminate partial information when generating resource indication information.

Alternatively, it is used as another embodiment, in 630, when whether the identification information of station that the first frequency range is distributed in the identification information of station and previous time period that site identity duplicate message is distributed specifically for the first frequency range in instruction current slot is identical, first is not included in site identity duplicate message set The corresponding site identity duplicate message of identification information of station that all frequency ranges are distributed in period；When whether the identification information of station that the first frequency range is distributed in the identification information of station and latter time period that site identity duplicate message is distributed specifically for the first frequency range in instruction current slot is identical, the corresponding site identity duplicate message of identification information of station that all frequency ranges are distributed in last period is not included in site identity duplicate message set.Two kinds of methods arranged side by side are properly termed as the first compression method.

The above method one, method two, method one ', method two ', method one " and method two " will be described respectively with reference to the first compression method respectively below.

Specifically, for method one, (identification information of station+site identity duplicate message) set after being compressed on first period can be：AID2 AID3 AID4 AID5, (identification information of station+site identity duplicate message) set on second period can be the AID8 0 of 1 AID6 of AID1,0 AID7 0.

For method two, (identification information of station+site identity duplicate message) set after being compressed on first period can be：The AID5 0 of 0 AID4 of AID1 1 AID2,0 AID3 0, (identification information of station+site identity duplicate message) on second period, which is gathered, to be：AID6 AID7 AID8.

For method one ', the two kinds of embodiments that can include in method one ' can use the first compression method, and the site identity duplicate message set after being compressed is 1000.

For method two ', site identity duplicate message collection is combined into 10000.

For method one ", the two kinds of embodiments that can include in method one " can use this compression method, and (frequency domain resource distributes configured information+site identity duplicate message) set after being compressed can be：001101100 001101111 1000.

For method two ", (frequency domain resource distributes configured information+site identity duplicate message) set can be：001101100 10000 001101111.

Figure 16 is the indicative flowchart of the method for the resource allocation of another embodiment of the present invention.Method shown in Figure 16 can be performed by receiving device.The receiving device can be website, or access point.Method shown in Figure 16 includes：

1610, receiving device receives the resource indication information for carrying out resource allocation in time domain and frequency domain from sending ending equipment, resource indication information includes persond eixis information and the first configured information for carrying out resource allocation on frequency domain, wherein, persond eixis information be included in time domain carry out resource allocation period number or persond eixis information be included in time domain carry out resource allocation period number and time segment length；

1620, the running time-frequency resource of distribution is determined according to resource indication information.

It should be understood that the first configured information can be used for carrying out resource allocation on frequency domain.First configured information can be the resource indication information in the resource allocation methods of existing use frequency division multiplexing, you can think the partial information in HE-SIGB.First configured information can include frequency domain resource distribution configured information, identification information of station and the site parameter information for indicating that frequency range is divided.

Specifically, the time segment length divided in some scheduling can be with identical.Now, persond eixis information can only include period number, and time segment length can be with implicit representation.Each isometric time segment length can be indicated according to period number and data field total length come recessive.Data field total length can be the summation of all data fields in time division multiplexing PPDU, the length that the data field total length can be indicated by the length field in L-SIG subtracts HE-SIG-A, and HE-SIF-B is calculated with HE-STF the and HE-LTF length before each data field.When the aliquant period number of data field total length, the time segment length that the length of last period can be more isometric than other is small.Alternatively, as another embodiment, persond eixis information when time segment length is identical can also include period number and time segment length.Wherein, time segment length can be one kind, that is, indicate the length of isometric period.Time segment length can also be two kinds, that is, indicate the length of isometric period and the length of last period.

Specifically, broadcast frame configured information can indicate which is used for sending broadcast frame (such as multicast frame) period.Alternatively, as one embodiment, the period number that some scheduling is divided is 4, for indicating that the broadcast frame configured information of multicast frame can be " 1010 ", it is broadcast frame then to represent the 1st period and the 3rd period, and the 2nd period and the 4th period are normal data frame.Alternatively, as another embodiment, when broadcast frame (such as multicast frame) is only being sent the 1st period, the broadcast frame configured information can also indicate whether first time period sends broadcast frame with 1 bit.For example period number is 4, and broadcast frame configured information can be " 1 ", then it represents that the 1st period was broadcast frame (multicast frame), and other 3 periods are normal data frame.
