    The draft of IMT-2020 describing the minimum requirements related to technical performance for IMT-2020 radio interface(s), which sets the goals for 5G.

    The draft document which will be finalized before the end of 2017 can be downloaded here: Minimum requirements related to technical performance for IMT-2020 radio interface(s).

    IMT-2020 lists in particular the following requirements

    PEAK DATA RATE
    • Downlink peak data rate is 20 Gbit/s.
    • Uplink peak data rate is 10 Gbit/s.
    PEAK SPECTRAL EFFICIENCY
    • Downlink peak spectral efficiency is 30 bit/s/Hz.
    • Uplink peak spectral efficiency is 15 bit/s/Hz.
    USER EXPERIENCED DATA RATE
    • Downlink user experienced data rate is 100 Mbit/s.
    • Uplink user experienced data rate is 50 Mbit/s.
    AREA TRAFFIC CAPACITY

    The target value for Area traffic capacity in downlink is 10 Mbit/s/m2 in the Indoor Hotspot – eMBB test environment.

    USER PLANE LATENCY
    • 4 ms for eMBB
    • 1 ms for URLLC
    CONTROL PLANE LATENCY
    • The minimum requirement for control plane latency is 20 ms.
    • Proponents are encouraged to consider lower control plane latency, e.g. 10 ms.
    CONNECTION DENSITY
    The minimum requirement for connection density is 1,000,000 devices per km2.

    ENERGY EFFICIENCY
    • Efficient data transmission in a loaded case;
    • Low energy consumption when there is no data.
    RELIABILITY
    The minimum requirement for the reliability is 1-10-5 success probability of transmitting a layer 2 PDU (protocol data unit) of 32 bytes within 1 ms in channel quality of coverage edge for the Urban Macro-URLLC test environment, assuming small application data (e.g. 20 bytes application data + protocol overhead).
    Proponents are encouraged to consider larger packet sizes, e.g. layer 2 PDU size of up to 100 bytes.

    MOBILITY
    The following classes of mobility are defined:
    – Stationary: 0 km/h
    – Pedestrian: 0 km/h to 10 km/h
    – Vehicular: 10 km/h to 120 km/h
    – High speed vehicular: 120 km/h to 500 km/h

    BANDWIDTH
    The requirement for bandwidth is at least 100 MHz.
    The RIT/SRIT shall support bandwidths up to 1 GHz for operation in higher frequency bands (e.g. above 6 GHz).
