Overview
Today’s wireless services and systems have come a long way since the rollout of the conventional voice-centric cellular systems. The demand for wireless access in voice and multimedia applications has increased tremendously. In addition to these, new application classes, such as enhanced mobile broadband (eMBB) communication, ultra-reliable and low latency communications (uRLLC), massive machine type communications (mMTC), and Internet of Things (IoT), have gained significant interest recently for 5G wireless networks. The trend on the variety and the number of mobile devices along with the mobile applications will certainly continue beyond 5G, creating a wide range of technical challenges like cost, power efficiency, spectrum efficiency, extreme reliability, low latency, robustness against diverse channel conditions, cooperative networking capability and coexistence, dynamic and flexible utilization of wireless spectrum, etc. In order to address these technical challenges, 5G waveforms and radio access technologies (RATs) should be much more flexible. The current 4G systems rely on the orthogonal frequency division multiplexing (OFDM) waveform, which is not capable of supporting the diverse applications that 5G and beyond will offer. This is because the traffic generated by 5G and beyond is expected to have radically different characteristics and requirements when compared to current wireless technology. For 5G to succeed, numerous waveform alternatives have been explored to best meet its various technical requirements. However, none of the alternatives were able to address all the requirements at the same time. During the standardization of 5G, one thing has become certain: there is no single enabling technology that can achieve all of the applications being promised by 5G networking. This will be even more pronounced beyond 5G. For this purpose, the concept of using multiple OFDM numerologies, i.e., different parameterization of OFDM based subframes, within the same frame has been proposed in 3GPP discussions for 5G. This concept will likely meet the current expectations in multiple service requirements to some extent. However, since it is almost obvious that quantity of wireless devices, applications and heterogeneity of user requirements will keep increasing towards the next decade(s), the sufficiency of the aforementioned flexibility level remains quite disputable considering future expectations. Therefore, novel RATs facilitating much more flexibility are needed to address the aforementioned technical problems.
The aim of this Special Issue is to provide a forum for the latest research and advances in the field of RATs for beyond 5G wireless networks. Potential topics include, but are not limited to:
- Alternative waveforms
- Low latency and low complexity waveforms
- Energy and spectral efficient waveforms
- Novel hybrid and flexible waveforms
- Waveform design for multiple-input multiple-output (MIMO) systems
- Adaptive, flexible, differential and cognitive OFDM
- Non-orthogonal waveform design
- Physical layer security in OFDM
- Index modulation-based waveforms
- Millimeter-wave waveform design
- Effect of hardware impairments on the waveform design
- Waveform design for vehicular, device-to-device (D2D) and machine-to-machine (M2M) communications
