Does Xiaomi need to pay patent fees to Huawei?

Need to talk about Huawei's base station patent first. Many people think that Xiaomi uses Huawei's base station and does not give Huawei patent fees. But the base station was bought by China Mobile, China Telecom and China Unicom, and the operators gave it to Xiaomi. Why can Huawei still collect patent fees? You bought a Huawei TV to show PPT to customers. Does Huawei want to ask you for patent fees? And when the mobile phone is connected to the network, the manufacturer has paid the network access fee, including the patent fee related to communication, and the Ministry of Industry and Information Technology will partially return it to the operators and Huawei and other equipment vendors. Secondly, the mobile phone baseband chip involves patents. A few years ago, we often heard that Samsung sued Apple, Huawei sued Apple, and domestic mobile phone manufacturers were pointed out. Now there is no such news. Why? Because chip manufacturers such as Qualcomm, MediaTek and Samsung integrate all patents and solve them through cross-licensing, that is to say, Xiaomi buys chips from Qualcomm, which involves the cost of Huawei patents. Xiaomi will be given to Qualcomm first, and then to Huawei from Qualcomm.
