Summary form only given. As cellular-IoT has been one of the key driving forces to 5G, spectrally efficient support for heterogeneous services that have quite different requirements is becoming ever so important, and OFDM and its variant SC-FDMA to support all 5G service scenarios is being questioned. The new waveforms (alternatives to OFDM) are mainly driven by low latency access, fragmented spectrum utilization, relaxed synchronism and robustness in super high speed, which are unprecedented challenges in 5G. The speech will talk about FBMC as a potential candidate waveform, satisfying non-strict synchronism, good spectrum-confinement and high spectrum efficiency.
