The specific embodiment of the present invention is explained.
As it is shown in figure 1, embodiments provide a kind of data transmission method, described method can be wrapped
Include following steps:
Step 11, it is judged that whether the speed of data to be transmitted is higher than the first scheduled rate.
In being embodied as, described femto cell, before sending data to the terminal of correspondence, must be treated
Transmission data carry out respective handling.Specifically, described femto cell adds school after described data to be transmitted
Test data, constitute transmission block.Described femto cell can be treated according to the transmission of present channel bandwidth estimation
The speed of transmission data, and then described data modulation is set according to the speed of described data to be transmitted,
It is other scheduling resource of described terminal distribution finally according to the modulation system of described data.Described terminal exists
Receive described femto cell distribution above-mentioned scheduling resource after, can in corresponding resource block location,
The demodulation mode corresponding with described modulation system is used to receive described data.
In being embodied as, the value of described first scheduled rate and the modulation system of described data.Such as,
Described first scheduled rate can proceed as follows setting: when modulation system is QPSK modulation
Time, described first scheduled rate is 15Mbps；When modulation system is to comprise the quadrature amplitude of 16 kinds of symbols
