Independent intellectual property is a standard or format that we put forward ourselves. As for the hardware, we still can't make many core parts (or the performance is not good enough) or we have to import them.
Just like TD-scdma for 3G mobile phones, the standard is nominally from China, but many core patents are still from abroad, as are the processing chips of base stations or mobile phones. These are the key points. On the whole, we still have a gap.
