Description

A kind of method and device of data transfer

Technical field

The present invention relates to the communications field, particularly a kind of method and device of data transfer.

Background technology

OFDM (Orthogonal Frequency Division Multiplexing, english abbreviation： OFDM) be Current wireless communication basic transmission means, be widely used in Long Term Evolution (Long Term Evolution, english abbreviation：LTE), worldwide interoperability for microwave accesses (Worldwide Interoperability for Microwave Access, english abbreviation：WiMAX), Wireless Fidelity (Wireless Fidelity, English Text abbreviation：The wireless communication system such as WiFi).Moreover, OFDM is also further applicable to fixed network biography Defeated, the such as transmission means such as optical fiber, copper stranded conductor, cable.The ultimate principle of OFDM is to utilize subcarrier Orthogonality allow in the range of, subcarrier spacing is compressed to minimum, this aspect can guarantee that to be formed many Road is parallel and non-interfering path, at the same again can lift system efficiency of frequency employment.

Further, as OFDM has above characteristic, if the non-interfering sub- load by OFDM The multiple users of wavelength-division dispensing, just can realize access or the data transfer of multi-user using OFDM, this It is exactly OFDM (Orthogonal Frequency Division Multiple Access, English contracting Write：OFDMA).The parallel transmission that multi-user data can be realized using OFDMA, is to improve data The effective means of transmission concurrency.For upgoing O FDMA is transmitted, multiple STA are needed in different sons Take synchronous transmitting data packet.In order to reach synchronous purpose, access point (Access Point, English Abbreviation：AP transmission trigger frame trigger frame) is needed to give multiple websites (Station, english abbreviation： STA), short frame period (Short Inter-Frame Space, english abbreviation that STA receives trigger frame are worked as： ) or certain intervals (X Inter-Frame Space, english abbreviation SIFS：XIFS need to stand after) Upstream data packet is transmitted.

In transmission opportunity (Transmit Opportunity, an english abbreviation：TXOP, in), AP can be with The multi-subscriber dispatching transmission of downlink and uplink is continuously carried out, for a STA, in a TXOP, AP needs to transmit downlink frame to which, and asks for uplink frame to which.AP downlink transfers first send downlink frame Give STA.After STA receives downlink frame, need to transmit up confirmation block or acknowledgement frame immediately.If AP It is also desirable that asking for uplink frame to STA, then also need to retransmit a trigger frame, when STA is received again by this After individual trigger frame, the transmission of uplink frame can be just carried out.If from whole flow process as can be seen that AP and STA wants to complete a complete descending and transmitting uplink data, and AP needs additionally to send a triggering again Frame, so, increases the expense of system.

In prior art, it is possible to use medium education (Media Access Control, english abbreviation： MAC) the polymerization of frame, that is, using MAC protocol data module (MAC Protocol Data Unit, English abbreviation：MPDU aggregate frame aggregation protocol data module (Aggregate-MPDU, English contracting) Write：A-MPDU the polymerization of different types of frame) is carried out, can be included in an A-MPDU multiple A-MPDU subframes, in each A-MPDU subframe, carry MPDU.If first MPDU For acknowledgement frame, second MPDU is Data frames, then can achieve different types of mac frame carry out while Transmission.

As this is polymerized to the polymerization in MAC layer face, different types of mac frame is needed using identical thing Reason parameter, such as modulating-coding strategy (Modulation and Coding Scheme, english abbreviation： MCS), space-time fluxion (Number of Spatial and Time Stream, english abbreviation：NSTS) etc.. But system is different to acknowledgement frame from the robustness requirement of Frame, it is often desired to which acknowledgement frame can be more Plus robust.For example, when being designed, it is often desired to Packet Error Ratio (the Packet Error of acknowledgement frame Rate, english abbreviation：PER) 1% can be less than；And for Frame, Packet Error Ratio is less than 10%. If requiring that different mac frames condense together by two kinds, a wherein side can only be yielded to.If simultaneously using mistake The higher MCS of report rate, the then inadequate robust of the acknowledgement frame that can be caused；If simultaneously relatively low using Packet Error Ratio MCS, then can cause the transfer rate of Frame slack-off, affect system throughput.

Specific embodiment

The characteristics of embodiment of the present invention connection confirming frame, devises the number that a kind of scheduling of resource indicates relative simplicity According to packet.As confirming (Acknowledgement, english abbreviation：ACK) frame, block confirm (Block ACK, english abbreviation：BA) control frame as frame has following characteristics：

1st, relatively robust higher transmission mode is needed, generally requires and be operated in the relatively low MCS of Packet Error Ratio Under, as the frame length of itself is less, the symbolic number that transmits needed for which also will not be very big.

If the parameters such as 2 space-time fluxions and MCS are relatively fixed, the resource block size occupied by which can be with It is relatively fixed, it may not be necessary to which extra resource indicates the number of symbolic number shared by which.

Above characteristic is based on, the embodiment of the present invention has carried out following design to data packet structure：First will Data division is divided into very first time block and the second time block, and need not be individually inside each time block Efficient short training sequence (High Efficient-Short Training Field, english abbreviation：HE-STF) With efficient long training sequence (High Efficient-Long Training Field, english abbreviation：HE-LTF), But share HE-STF and HE-LTF.And because sharing HE-STF and HE-LTF, this needs first Time block and the second time block are using identical NSTS, beam shaping (Beamforming, English contracting Write：) and Space-Time Block Coding (Space-Time Block Coding, english abbreviation BF：STBC) etc. The physical parameter of empty time stream, when otherwise one HE-STF and HE-LTF cannot be accurately finished first Between block and the second time block automatic growth control (Automatic Gain Control, english abbreviation：AGC) With channel estimation.

The embodiment of the invention discloses a kind of method and device of data transfer, referring to right shown in Fig. 2 One embodiment of the method for data transfer provided by the present invention is described in detail.

In the embodiment of the present invention, the method for the data transfer includes：

101st, site STA receives the packet that access point AP sends, and the packet includes resource Schedule information and data field, the resource scheduling information include the physical parameter of empty time stream, the money Source schedule information also includes that the first configured information, first configured information are used for indicating each orthogonal frequency The quantity of the time block included by the data field on multiple access OFDMA subbands；

STA and AP carries out data interaction by sending mutually packet, is sent in the AP described In the packet of STA, the packet needs to include the data field for transmitting data information, Also need to include for for indicating the resource scheduling information of the data field.The resource scheduling information In the physical parameter of the included empty time stream include space-time fluxion NSTS, beam shaping BF and sky The parameters such as time block code STBC, for indicating the transmission form of the data field, so that the STA The data field can be received according to the physical parameter of the empty time stream；

The data field is made up of time block, due to the embodiment of the present invention in, data field can be by more Individual time block composition, so in the resource scheduling information, need to include the first configured information, described First configured information is used for indicating that the data field is wrapped on each OFDM OFDMA subbands The quantity of the time block for containing, so that the STA can be according to first configured information to the data In field, different time blocks is received.

102nd, when first configured information indicates that the data field includes very first time block and the second time During block, the very first time block is joined using the physics of empty time stream described in identical with second time block Number is transmitted, and the very first time block carries medium education respectively with second time block Mac frame, the STA parse the MAC that the very first time block is carried respectively with second time block Frame；

When very first time block is included in data field and during the second time block, then the very first time block and institute State the second time block to be transmitted using the physical parameter of identical empty time stream, could be to described first Time block and the second time block are accurately finished automatic growth control AGC and channel estimation.Described first Time block carries mac frame respectively with second time block, and the mac frame can be dissimilar Frame, such as acknowledgement frame or Frame.As the very first time block distinguishes institute with second time block The type of the mac frame of carrying can be differed, and the content of that mac frame and effect are also differed.Such as, If mac frame is acknowledgement frame, then sent for indicating that the AP is successfully received the STA Data.As the STA and AP will proceed the data interaction of high level, so the STA Need to parse the very first time block mac frame entrained respectively with second time block.

In the embodiment of the present invention, AP is sent to the packet of STA includes resource scheduling information, data Field, resource scheduling information include that the first configured information, first configured information indicate the data Field includes that very first time block and the second time block, very first time block are carried respectively with the second time block Mac frame, and being transmitted using the physical parameter of identical empty time stream, the STA parsings described the The one time block mac frame entrained respectively with second time block.So, it is achieved that in same subband The transmission of different mac frames is carried out, the data interaction efficiency of AP and STA is improve, is reduced system Expense.

Above embodiment described very first time block and the second time block carries mac frame respectively, in reality In application, the physical parameter of non-empty time stream in resource scheduling information, can also be included come to being wrapped in time block The mac frame for including is indicated that wherein, the OFDM symbol length shared by very first time block can also The STA is notified by default or instruction, is specifically described below, with reference to shown in Fig. 2, the present invention In embodiment, another embodiment of the method for data transfer includes：

201st, site STA receives the packet that access point AP sends, and the packet includes resource Schedule information and data field, the resource scheduling information include the physical parameter of empty time stream, the money Source schedule information also includes that the first configured information, first configured information are used for indicating each orthogonal frequency The quantity of the time block included by the data field on multiple access OFDMA subbands；

Detailed content is with reference to described in S101.

202nd, when first configured information indicates that the data field includes very first time block and the second time During block, the very first time block is joined using the physics of empty time stream described in identical with second time block Number is transmitted, and the very first time block carries medium education respectively with second time block Mac frame, wherein, the very first time block takes preset number or indicated number purpose OFDM OFDM symbol, the STA according to the physical parameter of the empty time stream receive the very first time block and Second time block；

The very first time block takes preset number or indicated number purpose orthogonal frequency division multiplex OFDM symbol, As STA is when the data to time block are collected, need to be collected according to the length of time block. Conventionally, as only including a time block in data field, then STA can pass through to obtain number Total length according to field is obtaining the length of time block；And due to can in data field in the embodiment of the present invention To include more than one data block, so needing the setting for carrying out preset value to the length of very first time block Or individually indicate so that the STA according to preset number or can indicate number to the very first time The data of block are collected.

Specifically, the OFDM symbol of the very first time block occupancy preset number can be：Described first Time block takes the OFDM symbols that the AP carries out the fixation of default setting in advance to the very first time block Count mesh.I.e. before the AP carries out data interaction with the STA, the AP and STA Carry out protocol conventions or set in default in advance, both sides can know the OFDM of the very first time block in advance Length.

Or, the very first time block takes the OFDM symbol of preset number and can be：When described first Between block take the OFDM symbol number corresponding to the OFDMA subband sizes with the transmission data field Mesh.When certain subband has more than one time block, then first time block can be given tacit consent in the time On the OFDM symbol number that occupies corresponding with the size of subband on frequency domain.For example, when subband on frequency domain Size larger when, a such as Resource Block occupies 20MHz, then in time domain, corresponding symbolic number is just less, Such as 1 OFDM symbol；When the size of subband on frequency domain is less, a such as Resource Block only occupies 26 Individual subcarrier, then corresponding symbolic number just larger, such as 9 OFDM symbols in time domain.In a word, son There are accurate mapping relations in the OFDM symbol number taken with size and very first time block, therefore when When STA reads the size of subband on Resource Block frequency domain, it is possible to extrapolate shared by very first time block The symbolic number of OFDM.

Or, the scheduling resource information also includes that the second configured information, second configured information are used for Indicate the length of the very first time block；

Then the very first time block occupancy indicated number purpose OFDM symbol can be：The very first time block Take the OFDM symbol number of the length indicated by second configured information.Optionally, described Two configured informations can be field Seg (1) Alloc (Segment (1) Allocation, (time) block 1 Distribution), second configured information can be explicitly indicated out the symbols of the OFDM shared by the very first time block Number length；Second configured information can be with corresponding with subband size on frequency domain.For example, If the second configured information field carries out the instruction of OFDM symbol number, group mark using 2 bits When very little larger, such as 20MHz then 00 represents 1 symbol, and 01 represents 2 symbols；If subband size Less, such as 26 subcarriers then 00 represent 4 symbols, and 01 represents 8 symbols.In addition can lead to Whether the value for crossing Seg (1) Alloc is 0 realizing indicating whether the data field is multistage Multi Seg Function, i.e. it is 0 that Seg (1) Alloc is OFDM symbol number shared by 0 explanation very first time block, There is no the very first time block, then it represents that the subband only exists second time block.

It should be noted that in the embodiment of the present invention, the very first time block can include one or more Time block, and one or more time blocks that the very first time block includes are preset number or indicated number Purpose length so that the STA can accurately collect the data in the very first time block.

203rd, the STA collects institute according to the preset number or indicated number purpose OFDM symbol length State the data of very first time block；

STA then can be accorded with according to preset number or indicated number purpose OFDM after packet is received Number length collects the data of very first time block.

204th, total length and the very first time block of the STA according to the data field for getting The preset number of occupancy or indicated number purpose OFDM symbol length computation are obtained shared by second time block OFDM symbol length；

When the length of the very first time block is preset number or instruction number, then STA can determine institute The length of very first time block is stated, the total length further according to the data field for getting deducts described first The length of time block, then obtained second time fast OFDM symbol length.

It should be noted that the OFDM symbol length shared by the second time block can also be sent out by AP One of indication field in the resource scheduling information that send is indicated.

205th, described in OFDM symbol length of the STA according to shared by second time block is collected The data of the second time block；

After the length of second time block is obtained, then the STA can be according to second time block Length collect the data of second time block.

206th, the resource scheduling information also includes the second non-empty time stream corresponding with second time block Physical parameter, the physical parameter of the second non-empty time stream are used for indicating entrained by second time block The code modulation mode of mac frame；The very first time block is joined using the physics of the default first non-empty time stream Number indicates the code modulation mode of the mac frame entrained by the very first time block；The STA is according to institute The physical parameter for stating the second non-empty time stream parses the mac frame entrained by second time block；

After STA has collected the mac frame for being carried in very first time block and the second time block respectively, in order to Accurate data interaction is carried out with AP, then needs to parse mac frame, obtained in mac frame in detail Thin instruction content.And parse mac frame, then the code modulation mode for obtaining MAC is needed, so, The physics ginseng of the second non-empty time stream corresponding with the second time block in resource scheduling information, can also be included Number, the physical parameter of the second non-empty time stream are used for indicating the mac frame entrained by second time block Code modulation mode, the physical parameter of non-empty time stream can include modulating-coding strategy (Modulation and Coding Scheme, english abbreviation：) and low density parity check code (Low Density Parity MCS Code, english abbreviation：LDPC) etc..So so that the STA can be according to second non-NULL When the physical parameter that flows second time fast entrained mac frame is parsed.

And the physical parameter for the non-empty time stream entrained by described first piece, default MCS can be adopted And LPDC.For example, for modulating-coding strategy MCS, can all the time using adopting MCS0； For coded system, for the less situation of size on frequency domain, acquiescence adopts Binary Convolutional Code (Binary Convolution Code, english abbreviation：BCC) coded system, i.e. LDPC=0, and on frequency domain Larger-size situation, acquiescence adopt LDPC coded systems, i.e. LDPC=1.

Alternatively, the mac frame entrained by the very first time block, it is also possible to by the first non-empty time stream Physical parameter is explicitly indicated.I.e. described resource scheduling information also includes the physics with the first non-empty time stream Parameter and the physical parameter of the second non-empty time stream, the physical parameter and described first of the first non-empty time stream Time block is corresponding.So, the physical parameter of the first non-empty time stream has been explicitly indicated entrained by very first time block Mac frame MCS or LDPC, alternatively, the physical parameter of the first non-empty time stream can also A modulating-coding parameter of the mac frame entrained by the very first time block is only indicated, is such as only indicated MCS, and LDPC is using the parameter of acquiescence.

207th, the STA is according to during the physical parameter of default first non-empty time stream parsing described first Between mac frame entrained by block；

Alternatively, when also including in the resource scheduling information that corresponding with the very first time block first is non- During the physical parameter of empty time stream, then the STA can be according to the physical parameter solution of the described first non-empty time stream Analyse the mac frame entrained by the very first time block.

In the embodiment of the present invention, the OFDM symbol length shared by very first time block can be default length Degree, just can be without indicating shared by the very first time block in the resource scheduling information that such AP sends OFDM symbol length, saves the expense of system；Or the length of the very first time block is adjusted for resource Length in degree information indicated by the second configured information, so so that the length of very first time block is more clever Living.The very first time block can adopt the physical parameter of default non-empty time stream, and so, AP sends In resource scheduling information just can without indicate the mac frame entrained by the very first time block non-NULL when The physical parameter of stream, also saves the expense of system.
