This document provides an overview of 5G including use cases, performance targets, network architecture, and a collaboration between industry partners and the University of Salford. It outlines the high speed and low latency capabilities of 5G as well as the spectrum bands being used. It also summarizes the functional components of the 5G network architecture and the research progress being made through the 5G testbed at the University of Salford.

5. Selected parameters
ITU-R IMT-2020 Requirements
> The minimum requirements for eMBB peak data rate are
as follows:
– Downlink peak data rate is 20Gbps
– Uplink peak data rate is 10Gbps
> The minimum requirements for eMBB peak spectral
efficiencies are as follows:
– Downlink peak spectral efficiency is 30 bit/s/Hz
– Uplink peak spectral efficiency is 15 bit/s/Hz
> The target values for the user experienced data rate are
as follows in the Dense Urban – eMBB test environment:
– Downlink user experienced data rate is 100Mbps
– Uplink user experienced data rate is 50Mbps
> The minimum requirements for 1-way user plane latency
over the radio interface are:
– 4 ms for eMBB
– 1 ms for URLLC (3GPP target = 0.5ms)
> The minimum requirement for control plane latency is
20ms (Proponents are encouraged to consider lower
control plane latency, e.g. 10ms) 3GPP target = 10ms)
> The minimum requirement for mMTC connection density
is 1,000,000 devices per km2
> The minimum requirement for eMBB and URLLC mobility
interruption time is 0ms

6. Pioneer bands:
> 700 MHz band - to provide a coverage layer
> 2 x 30 MHz + 20 MHz centre gap - SDL - 2019
> 3.4 - 3.8 GHz band – to provide a large amount of contiguous
spectrum for high-data rate and low-latency services and a capacity
solution in congested areas
> 150 MHz in the 3.4 - 3.6 GHz band in 2018
> 116 MHz in 3.6 - 3.8 GHz band in 2019
> 26 GHz band - to provide “fibre-like” data rates and very low
latencies at short distance, as a capacity solution in very congested
hotspots
> 24.25 - 27.5 GHz - date tbd, likely auction post WRC2019
Note: Existing bands could be refarmed to 5G and more bands are likely in the future…

collaborative research activity
> On-going research programme involving a PhD student and
academic staff along with industrial partners
> Presentation delivered at 5G World Congress in London during
2017, paper and poster at upcoming antennas and propagation
conference (EurAPP 2018)
> Other conferences and publications in planning
> Results to be shared with ETSI ISG on millimeter wave
transmission (mWT)
> Build on industry collaboration to further develop test-bed and
understand how to best utilise campus environment as live test
facility
> Engage wider student and staff community in live 5G
experimentation as a basis for new and innovative campus
