New 5G air interface: challenges for efficient multi-service coexistence for 5G below 6 GHz
This chapter has provided a view of the current service and use case landscape for 5G networks. It also performs a selection among these use cases so that a flexible air interface design for spectrum below 6 GHz can be performed. Challenges for this design on link and system levels are then briefly discussed along with their research topics and the evaluation methodology for the corresponding technical components. We finally note that the design of a new air interface is heavily composed of topics requiring standardization, e.g., waveform and frame design, PHY layer procedures, transceiver processing (interference management, multiuser reception, etc.), channel coding, adaptive coding and modulation, etc. These are all topics that imply interfaces, messages, signalling, protocols (all of which are standardized in 3GPP) rather than proprietary algorithmic solutions and an important challenge for researchers is to be able to interact with standardization bodies, especially 3GPP, in a timely manner.
