- Evolved Mobile Broadband (eMBB)
- Ultra-Reliable and Low-Latency Communications (URLLC)
- Massive machine-type communications (mMTC)
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…).
- CP-OFDM ranks best on the performance indicators that matter most.
- Low complexity with multi antenna technologies and high spectral efficiency and low implementation complexity.
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”
The eMBB DFT-S-OFDM, which has a lower PAPR than CP-OFDM (equivalent to SC-FDMA in LTE), is still possible in UL without MIMO deployment scenario, where UL transmission is only done through one stream).
