Key Technology Challenges for 5G and Beyond Wen Tong Huawei Fellow, IEEE Fellow Chief Technology Officer, Wireless Network Huawei Technologies Co., Ltd., China Abstract  As 5G became a global-scale dominant mobile technology to drive the digital transformation for all business and industries, the implementation and development of 5G network infrastructure to meet all the requirements for 5G defined by ITU remains a technology challenge. In this talk, we present the open issues and state-of-art solutions in the three key use-cases for 5G: (1) emBB (2) URLLC (3) mMTC; unlike the previous generation of wireless networks, 5G will address the diverse technologies spanning from cellular frequency to mmWave frequency, from global coverage macro-cell networks to hot-spot UDN, from consumer based internet access to industrial grade cyber-physical tactile internet, from purpose designed networks to software defined virtualized networks. These challenges will continue to drive the landscape for 5G and beyond, as such, we will present a deep-dive into two enablers, i.e.,  spectral efficiency and end-to-end network slicing.
