enhanced device and network-level capabilities, tightly coupled with
intended applications. The following eight parameters are key capabilities
for IMT-2020 5G:
Capability Description 5G target Usage scenario
Peak data rate Maximum achievable data rate 20 Gbit/s eMBB
User experienced data rate Achievable data rate across the coverage area
1 Gbit/s eMBB
Latency Radio network contribution to packet travel time 1 ms URLLC
Mobility Maximum speed for handoff and QoS requirements 500 km/h
eMBB/URLLC
Connection density Total number of devices per unit area 106/km2
MMTC
Energy efficiency Data sent/received per unit energy consumption (by
device or network) Equal to 4G eMBB
Spectrum efficiency Throughput per unit wireless bandwidth and per
network cell 3–4x 4G eMBB
Area traffic capacity Total traffic across coverage area 1000 (Mbit/s)
/m2 eMBB
和“大的战乱”比起来，我觉得要清晰的多。 |
