TD-SCDMA中的扰码与物理小区标识有什么关系？

Question

比如TD-SCDMA的physicalCellIdentity是73，那么它对应的scrambling code （扰码）应该是多少呢？以下是对应的外部TD-S的临区信息：

根据以上的信息能得出扰码为多少吗？

Answer 1

在TD-SCDMA中，扰码可称作CPI(cell parameter id)，它与主频一起标识了一个小区。有些厂家也将它作为物理小区标识（PCI），在TDD-LTE中，就沿用了这一称呼。所以，从截取的信息来看，其实该小区的扰码即是物理小区标识（physicalCellIdentity）—73.

以上只是我个人的理解，仅供参考。
