ITU-R IMT-2020 requirements - selected parameters
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

Highlights
• 1.3Gbps to test equipment (30 MHz LTE + 40 MHz NR)
• 600Mbps to Huawei 5G CPE (5 MHz LTE + 40 MHz NR)
• 4T4R LTE (15 MHz 2100 + 15 MHz 2600) with 64T64R NR

Spectrum

British Telecommunications plc 2018
Ofcom and RSPG has identified three pioneer bands for 5G in Europe
700 MHz band – to provide a coverage layer
2 x 30 MHz + 20 MHz centre gap – SDL – 2019 auction
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 (auction complete) - 116 MHz in 3.6 - 3.8 GHz band – 2019 auction
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 and more bands are likely in the future…]

• Current FDD LTE is typically 2T2R (2x2) or 4T4R (4x4), 5G TDD will typically utilise 8T8R (8x8) and 64T64R (64X64)
• 16T16R and 32T32R systems are expected in the near future, along with hybrid (active/passive) antennas
• 3.5 GHz NR downlink will exceed uplink reach (particularly with M-MIMO) however systems supports a flexible
separation of control and user plane which allows downlink and uplink to be on different bands and technologies

Summary
• 5G will support:
• enhanced Mobile Broadband (eMBB)
• Ultra-Reliable & Low Latency Communications (URLLC)
• massive Machine Type Communications (mMTC), use cases
• 5G will rely on LTE (R15 eLTE) to support device connectivity (radio and EPC+)
• EN-DC enables maximum performance for initial eMBB services
• RAN and Core networks offer flexible functional decomposition and placement of
network elements (increased use of software and network cloud)
• Network slicing enables secure virtual private networks with guaranteed SLAs
• URLLC is an overlay and requirements will vary based on use cases
• Initial MTC use cases will be addressed by NB-IoT (4G) and evolve to 5G
