What are the requirements for 5G in IMT-2020?

The requirements for 5G in IMT-2020, the global standard for mobile communications, encompass a peak data rate of 20 Gbps downlink and 10 Gbps uplink, ultra-low latency, support for up to 1 million devices per square kilometer, high-speed mobility of 500 km/h, energy efficiency, versatile spectrum usage, 99.999% availability, extensive coverage, diverse Quality of Service capabilities, robust security, network slicing, and adequate backhaul and fronthaul support.

These requirements aim to enable a wide range of applications, from high-speed broadband to mission-critical services and IoT, within a globally interoperable 5G network.

Here are the details of the requirements for 5G in IMT-2020:

  1. Peak Data Rate:
    • For enhanced mobile broadband (eMBB) communication, the peak data rate should be at least 20 Gbps for downlink (DL) and 10 Gbps for uplink (UL).
  2. User Experience Data Rate:
    • The user experienced data rate should be a minimum of 100 Mbps for DL and 50 Mbps for UL.
  3. Latency:
    • The latency should be extremely low, with a round-trip time (RTT) of less than 1 millisecond for specific use cases that require ultra-low latency.
  4. Connection Density:
    • 5G in IMT-2020 should support a high density of connected devices. It should be able to handle up to 1 million devices per square kilometer.
  5. Mobility:
    • Seamless mobility is crucial. The network should support high-speed mobility of up to 500 km/h, which is important for applications in high-speed trains and vehicles.
  6. Energy Efficiency:
    • 5G networks should be energy-efficient, ensuring that the technology minimizes power consumption while delivering high-performance services.
  7. Spectrum Usage:
    • IMT-2020 specifies that 5G should use the spectrum efficiently and be able to operate in various frequency bands, including millimeter-wave (mmWave) frequencies.
  8. Reliability and Availability:
    • The network should provide high reliability and availability, with a target availability of 99.999%.
  9. Coverage:
    • The coverage area should be extensive, reaching remote and rural areas, and the technology should support both indoor and outdoor environments effectively.
  10. Quality of Service (QoS):
    • The 5G network should provide diverse QoS capabilities to cater to various applications, including mission-critical services, eMBB, and massive machine-type communications (mMTC).
  11. Security:
    • Security is a paramount concern. 5G in IMT-2020 should include robust security mechanisms to protect data and user privacy.
  12. Network Slicing:
    • The technology should support network slicing, allowing network operators to partition a single physical network into multiple virtual networks to meet the specific requirements of different services and applications.
  13. Backhaul and Fronthaul:
    • Adequate backhaul and fronthaul capabilities should be available to support the high-speed, low-latency requirements of 5G.

These requirements are designed to ensure that 5G in IMT-2020 can support a wide range of applications and services, from ultra-high-speed broadband to mission-critical communications and the Internet of Things (IoT). Meeting these standards is essential for the development of a globally interoperable 5G network.
