The detection reference signal determines.
7. the business transmitting method based on cooperation according to claims 1 to 3 any one, 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-
It is the Internet resources that first communication node is negotiated in advance with second communication node to determine resource.
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 one(0,1)Between random number, if the random number is more than 0.5, described in the transmission group use
Predetermined resource sends the transmission data block.
9. the business transmitting method based on cooperation according to claims 1 to 3 any one, which is characterized in that
In the step S7, the T third communication node receives the transmission group and is sent 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, and process is:The T third communication node receives the 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 is received with second communication node on the described first sub- running time-frequency resource merges, so
It is decoded again afterwards.
10. the business transmitting method based on cooperation according to claims 1 to 3 any one, 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 by predetermined resource to second communication node
Request is examined, after second communication node receives the positioning with reference to request, positioning ginseng is sent to first communication node
Examine signal, wherein the predetermined resource is that the network that first communication node is negotiated in advance with second communication node provides
Source.
