7. according to claim 1 to described in 3 any one based on the business transmitting method of cooperation, which is characterized in that if institute It states transmission group and is not received by whether second communication node is properly received institute in the transmission transmission data block 100ms The feedback information of transmission data block is stated, then the transmission group is obtained corresponding with the reliability step information by competitive way Predetermined resource, and the transmission data block is sent to second communication node by the predetermined resource, wherein described pre- Determining resource is the Internet resources that first communication node and second communication node are negotiated in advance.

8. the business transmitting method according to claim 7 based on cooperation, which is characterized in that the competitive way is described Transmission group generates random number between one (0,1), if the random number is greater than 0.5, described in the transmission group use Predetermined resource sends the transmission data block.

9. according to claim 1 to described in 3 any one based on the business transmitting method of cooperation, which is characterized in that

In the step S7, the T third communication node receives the transmission group and sends out on the described second sub- running time-frequency resource The transmission data block sent, the transmission data received on the described first sub- running time-frequency resource with second communication node Block carries out combined decoding, process are as follows: the T third communication node receives transmission data transmitted by the transmission group After the sampled signal of block, the sampled signal is sent to second communication node, second communication node is adopted described The transmission data block that sample signal receives on the described first sub- running time-frequency resource with second communication node merges, so It is decoded again afterwards.

10. according to claim 1 to described in 3 any one based on the business transmitting method of cooperation, which is characterized in that if institute It states transmission group and is not received by whether second communication node is properly received institute in the transmission transmission data block 100ms The feedback information of transmission data block is stated, then the transmission group sends positioning ginseng to second communication node by predetermined resource Request is examined, after second communication node receives the positioning with reference to request, the first communication node of Xiang Suoshu sends positioning ginseng Examine signal, wherein the predetermined resource is that the network that first communication node and second communication node are negotiated in advance provides Source.
