5G: Key performance requirements of IMT-2020.

Hi guys, welcome to Part 2 of 5G learning. Today we will focus on the KPIs of IMT-2020. ITU-R has defined a series of requirements for 5G in the IMT 2020 vision and the 3GPP standards body has been defining the detailed standards to meet ITU requirements.

1)  Data Rate:

(IMT2020=5G) Peak Data rate: DL= 20 Gb/s

                                                      UL= 10 Gb/s

(IMT advanced=4G) Peak Data rate: DL= 1 Gb/s

2)  User experienced (Edge throughput) Data Rate:

(IMT2020=5G) User experienced Data rate: DL= 100 Mb/s

                                                                             UL= 50 Mb/s

(IMT advanced=4G) User experienced Data rate: DL= 10 Mb/s

Note: User experienced Data Rate depends on different use cases like Broadband access in dense areas or Broadband access in crowded areas or Massive low cost/long range/ low power MTC or Broadband MTC or Ultra-low latency or resilience and traffic surge etc.

In the above example for Broadband access in dense area, data rate required is 1Gbps but for resilience and traffic surge data rate requirement is 0.1 Mbps.

3) Area traffic capacity:

(IMT2020=5G) Area traffic capacity:  10 Mbit/s/m²

(IMT advanced=4G) Area traffic capacity:  0.1 Mbit/s/m²

Note: Area Traffic Capacity is considered for a particular area (dense area, crowded area, rural area, urban area etc.) and the spectrum used in that area.

4) Spectrum efficiency:

(IMT2020=5G) Spectrum efficiency:  Peak DL = 30 bit/s/HZ

                                                                 Peak UL = 15 bit/s/HZ

                                                                 Average DL = 3.3~9 bit/s/HZ

                 Average UL = 1.6~6.75 bit/s/HZ

5) Latency:

(IMT2020=5G) Latency:  1 ms

(IMT advanced=4G) Latency:  10ms

Note: For IMT2020 we have considered user plane latency to be ~1ms - 4ms and for control plane 20ms.

E2E latency varies for different use cases. For example, for some IoT devices regular communication is not critical and for some low power MTC devices latency varies from seconds to hours.

6) Mobility:

(IMT2020=5G) Mobility:  0km/hr ~ 500km/hr

(IMT advanced=4G) Mobility:  0km/hr  ~ 300Km/hr

Note: Mobility may also depend on pedestrians as well as on demand.

7) Connection density:

(IMT2020=5G) Connection density: 1000000 devices per km²
