Abstract :
Fast growth of mobile internet and internet-of-things has propelled the concept formation and research on 5G wireless communications systems which are to be standardized around 2020 (IMT-2020). There will be diverse application scenarios expected for 5G networks. Hence, key performance indicators (KPIs) of 5G systems would be very diverse, not just the peak data rate and average/edge spectral efficiency requirements as in previous generations. For each typical scenario, multiple technologies may be used independently or jointly to improve the transmission efficiency, to lower the cost, and to increase the number of connections, etc. Key enabling technologies are discussed which include massive MIMO, ultra-dense deployment specific techniques, nonorthogonal transmission, high frequency communications, etc.
