As shown in Figure 5, in the data transmission method that the embodiment of the invention provides, the one TDD system uses the first frequency band (being carrier wave 1) to carry out the up-downgoing transfer of data, the 2nd TDD system uses the second frequency band (being carrier wave 2) to carry out the up-downgoing transfer of data, is reserved with guard band between the first frequency band and the second frequency band; And:
The one TDD system and/or the 2nd TDD system also use the first physical resource (being resource 1) to carry out downlink data transmission; The first physical resource is the time/frequency source block that is made of described guard band and very first time section; Very first time section is that a TDD system carries out the shared downgoing time section of downlink transfer, carries out minimum time section in the shared downgoing time section of downlink transfer or the part-time section of this minimum time section with the 2nd TDD system.
In Fig. 5; because a TDD system carries out the shared downgoing time section of downlink transfer in carrier wave 1; in carrier wave 2, carry out the shared downgoing time section of downlink transfer less than the 2nd TDD system; therefore; resource 1 is carried out the shared downgoing time section of downlink transfer by guard band and a TDD system and is consisted of; certainly, also can be consisted of by the part-time section of guard band and this downgoing time section.If the up-downgoing proportional arrangement of a TDD system and the 2nd TDD system is exchanged; then the 2nd TDD system carries out the shared downgoing time section of downlink transfer in carrier wave 2; in carrier wave 1, carry out the shared downgoing time section of downlink transfer less than a TDD system; at this moment; resource 1 is carried out the shared downgoing time section of downlink transfer by guard band and the 2nd TDD system and is consisted of; certainly, also can be consisted of by the part-time section of guard band and this downgoing time section.

In above-mentioned five kinds of execution modes, a TDD system and/or the 2nd TDD system can use the first physical resource transmitting physical DSCH Downlink Shared Channel (PDSCH), perhaps, use the first physical resource transmission PDSCH and down control channel.
The one TDD system and/or the 2nd TDD system can use the second physical resource transmitting physical Uplink Shared Channel (PUSCH), perhaps, use the second physical resource transmission PUSCH and ascending control channel.

The 3rd TDD system can adopt the up-downgoing proportional arrangement identical or different with a TDD system; Perhaps, the 3rd TDD system adopts the up-downgoing proportional arrangement identical or different with the 2nd TDD system.
The one TDD system and the 2nd TDD system can obtain the frame timing information to method, system in advance, with according to the frame timing information that gets access to method, system is reached time synchronized.For example, the frame timing information of a TDD system acquisition the 2nd TDD system, a TDD system according to frame timing information so that the frame head of the frame head of native system and the 2nd TDD system reaches time synchronized etc.
The 3rd TDD system also needs to obtain the frame timing information of a TDD system and the 2nd TDD system, chooses time slot according to the frame timing information that gets access to and carries out the up-downgoing transmission, disturbs to avoid producing cross time-slot with a TDD system and the 2nd TDD system.For example, can not there be lap in the ascending time slot that is used for uplink that the 3rd TDD system chooses with the descending time slot of a TDD system and the 2nd TDD system in time, disturbs thereby avoid producing cross time-slot with a TDD system and the 2nd TDD system; Same, can not there be lap in the descending time slot that is used for downlink transfer that the 3rd TDD system chooses with the ascending time slot of a TDD system and the 2nd TDD system in time, disturbs thereby avoid producing cross time-slot with a TDD system and the 2nd TDD system.
