Does TD-SCDMA need to pay CDMA patent fees to Qualcomm?

TD is a completely independent property right of China, and from its own point of view, it does not pay patent fees, but only introduces some basic technologies from abroad and pays only a small amount of patent fees.

Wscdma and cdma2000 have to pay patent fees, because they are not independently developed by China.

This is why the country strongly supports TD, but the development of TD is not as mature as wscdma and cdma2000, so TD is only in its infancy in China. It is estimated that it will take four or five years to be fully popularized.
