Having said that, 5G has a broad vision and envisages design targets that include, 10-100x peak date rate, 1000x network capacity, 10x energy efficiency, and 10-30x lower latency paving the way towards Gigabit wireless. Whilst, earlier network generations have been designed as general purpose connectivity platforms with limited differentiation capabilities across use cases, the situation is changing the definition of 5G/B5G networks. It will serve a larger portfolio of applications with a corresponding multiplicity of requirements ranging from high data rate to higher reliability to ultra-low latency going through high bandwidth and mobility.  The IMT 2020 requirements of 20 Gb/s peak data rate and 1 ms latency present significant engineering challenges for the design of 5G cellular systems. Meanwhile, International Telecommunication Union (ITU) has classified 5G services into enhanced mobile broadband (MB), ultra-reliable and low-latency communications (URLLC) and massive machine type communications (MTC) with a high variability of their performance attributes. 


LLC which refers to transmission technologies allowing for stringently bounded end-to-end latencies within the order of milliseconds and packet error rates on the order of 10−5 to 10−9 is arguably the most innovative feature brought in 5G, as it will be used for mission-critical communications, like reliable remote action with robots or coordination among vehicles. The current 3GPP requirement for URLLC includes the hard latency of one millisecond over the air interface and the system reliability of 99.999%. To cope with this new paradigm shift, 3rd Generation Partnership Project (3GPP) introduced a new air interface referred to as New Radio (NR). The primary goal of NR is to bring entirely new features and technologies such as ultra-lean communication, multi-connectivity, multi-service, beam centric, low latency and forward compatibility that are not necessarily backward compatible with current 4G LTE systems. 


The Release 16 of 3GPP, is particularly interested in a new class of services called ultra-High Speed Low Latency Communications (uHSLLC) e.g. mmWave V2X. However, although the mmWave bands can support massive peak data rates, delivering these data rates for end-to-end services while maintaining reliability and ultra-low-latency performance to support emerging applications and use cases will require rethinking all layers of the protocol stack. To realize such requirements, it is essential to combine mmWave with Mobile Edge Computing (MEC), a technology allocating storage and computation resources at the edge of the network to reduce latency. However, how to combine them effectively has not been fully discussed, especially for critical applications of strict latency constraints foreseen in 5G networks. Another critical issue in terms of cost is how to backhauling the mmWave small cell networks, knowing that it is impossible to provide Gigabit Ethernet backhaul everywhere. One of the solutions is to introduce self-backhauling technique using mmWave in combination with Software Defined Network (SDN) technology to reduce OPEX/CAPEX. In this workshop, we aim to collect papers that cover the aforementioned topics.
