8 and subframe 9 form after field.
In the internal structure of specific frame, control domain includes a subframe, by the first leading, record wireless control communications
Control zone and the first protection interval composition；The data field includes multiple subframes, leading, record traffic data by second
Data field and the second protection interval composition；The feedback field by record receive feedback command or feedback information feedback area and
Third protection interval composition.
Fig. 3 C can be specifically referred to, in preceding field, control domain is subframe 0, and subframe 0 is according to the works of the data wherein recorded
It is divided into the first leading, control zone and protection interval (i.e. the first protection interval) with difference；Feedback field includes the latter portion of subframe 4
Point, this part includes feedback area and the protection interval (i.e. third protection interval) of record feedback command or feedback information；Control
Subframe between domain processed and feedback field is data field, that is to say, that data field include subframe 1, subframe 2, the whole of subframe 3 and
The front portion of subframe 4；Wherein front end a part of subframe 1 is the second leading, rear portion, subframe 2 and subframe 3 of subframe 1
Whole and front end a part of subframe 4 be data field, part between data field and feedback field is between the protection of data field
Every (i.e. the second protection interval).The length of certain feedback field can be adjusted according to actual needs, and the length of data field is corresponding
It is adjusted.The structure of field is identical as the structure of preceding field afterwards, i.e., subframe 5 is control domain, and so on.
In specific self-organizing network, such as the self-organizing network that bandwidth is 20MHz, sample frequency is 30.72MHz,
Subframe 0 includes 14 OFDM symbols, wherein first 1 OFDM symbol of leading occupancy, the first protection interval occupies 1 OFDM symbol
Number, remaining is control zone；1~subframe of subframe 4, each subframe include 14 OFDM symbols, wherein the leading occupancy of the second of subframe 1
1 OFDM symbol, remaining is data field；Subframe 2 and 3 data field of subframe occupy all 14 OFDM symbols；The data field of subframe 4

For the smooth transmission for guaranteeing data, the minimum unit of the Internet resources reserved (Internet resources distributed in other words)
For the data field (i.e. 4 subframes) in field, the Internet resources that control domain does not pass through reservation are sent, and data field and feedback field are logical
The Internet resources for crossing reservation are sent.
Step S204: if record has the anti-of business datum reception failure from the feedback field of the received frame structure of destination node
Feedforward information then retransmits feedback information specified data domain.
Feedback field and data field correspond, and sending node refers in the ACK/NACK feedback that feedback field sends corresponding data domain
Show；The ACK/NACK that destination node receives corresponding data domain feeds back instruction；Sending node is believed in MAC layer based on the NACK of feedback field
Breath retransmits same bag data, and receiving node merges demodulation to the data packet.
Step S205: the wireless control communications that acquisition is carried from the control domain of the received frame structure of sending node, and according to
The wireless control communications are that sending node distributes Internet resources to receive business datum.
Step S206: the business datum of reception failure if it exists is then received in the feedback field addition business datum of frame structure
The feedback information of failure, and feed back to sending node to receive corresponding data field again.
For individual node, it is understood that there may be send the demand of data, be used as sending node at this time；There is also receive number
According to demand, at this time be used as destination node.During sending data, the main process for executing step S201-S204 is being connect
During receiving data, the main process for executing step S205 and S206, before 4 steps and do not have between 2 steps below
Strict sequence is not interfere with each other between the transmission data and reception data of individual node itself.
For individual data transformation task, then the cooperation of sending node and destination node is needed, is passed in individual data
In the implementation procedure of defeated task, sending node executes step S201-S204, and destination node executes step S205 and S206, and
There is stringent implementation procedure between each other.From timing, be successively: sending node executes step S201, and destination node executes step
Rapid S205, sending node execute step S202, and sending node executes step S203, and destination node executes step S206, send section
Point executes step S204, final to realize that data are transmitted in the wireless self-organization network of high-throughput.
In conclusion wireless control communications are sent to destination node by the control domain in frame structure, to reserve network money
Source；Business datum is added to the data field of frame structure, the reception feedback command of the business datum is added to frame structure
Feedback field；The data field and feedback field are sent to the destination node by the Internet resources reserved；If from the target
Record has the feedback information of business datum reception failure in the feedback field of the received frame structure of node, then retransmits the feedback
Information specified data domain.Corresponding data are respectively sent by control domain, data field and feedback field in the frame structure, in industry
