During proportioning, it can be required to select suitable ratio according to switching time, for example, alternative ratio includes：4:
1、2:1、1:1、1:2 and 1:4.For example, when the length for mixing micro- frame is 200 μ s, wherein, the protection interval in the micro- frame of the mixing
20 μ s are set to according to radius of society demand, up-downgoing ratio are being used for 2:It is upper in the micro- frame of the mixing in the case of 1
A length of 120 μ s during row data division, a length of 60 μ s during downlink data part.
It should be noted that in step 72, described proportioning is mainly according to traffic performance and rate requirement, except frequency domain
In addition, enough Resource Guarantee business are ensured in time；Such as 3D is without compression high definition video stream traffic, and possible configuration is multiple descending
Subframe+micro- frame.
