We need to do more technology innovation based on 4G networks, even bringing 5G technology into 4G networks. For example, 4T4R and massive MIMO. On the one hand, we need to start to build the ecosystem from now for 5G today. Huawei X Labs is a platform where we work with third parties to start building an ecosystem for 5G now. Therefore, we need to have more technology innovation for a good 5G network. On the other hand, we need to start to do technology innovation and ecosystem building from today based on 4G networks.
