CSI-RS is sent, and continues whether the n-th+2 system-frame of detection has CSI-RS to need hair in the n+1 system-frames
Send.
9. device according to claim 8, it is characterised in that the determination specifically for：It is described instantly
When one n+1 system-frame has CSI-RS to need transmission,
If current include the terminal of Second Type in net UE, in the n+1 system-frames according to CSI-RS
The transmission cycle send CSI-RS；
If the current terminal in the net all first kind of UE, next n+1 system-frames are not sent
CSI-RS, and continue whether detection n+2 system-frames have CSI-RS to send in the n+1 system-frames.
10. device according to claim 9, it is characterised in that the determination specifically for：Described
One type terminals are the terminal of transmission mode non-transmitting pattern 9 (TM9)；The Second Type terminal is biography
Defeated pattern is TM9 terminal.
