The URLLC services refer to future applications that require secure data communications from one end to another with ultra-high reliability and deadline-based low latency requirements. This type of quality-of-service is vastly different from that of traditional mobile broadband applications. In this article, we discuss the eMBB based on Cyclic Prefix Orthogonal Frequency Division Multiplexing (Filtered OFDM, Universally filtered OFDM, Pulse shaped OFDM…).
Main drawback of CP-OFDM is high PAPR, which could be reduced in a receiver agnostic way by using for example known technique like clipping and companding. Windowing is also a possibility to frequency localized OFDM. For more details on this choice, please refer to #Ericsson “Waveform and Numerology to Support 5G Services and Requirements”
