请问在TD-SCDMA中目标小区帧号(CFN)是指的什么

12-10

在TD-SCDMA中常说的系统帧号(SFN)，目标小区帧号(CFN)等是指的什么呢，怎样定义的，帧号又是什么呢？请各位明白人给予执教,非常感谢！

I only know the CFN, BFN and SFN in WCDMA, but
I think in TD-SCDMA system, it has a similar concept.
The frame numbers are used for:
node synchronization between the Node B and RNC
MCF entity syn. between RNC and UE
