应用场景

ITU-R has defined the following main usage scenarios for IMT for 2020 and beyond in their Recommendation ITU-R M.2083:

  • Enhanced Mobile Broadband (eMBB) to deal with hugely increased data rates, high user density and very high traffic capacity for hotspot scenarios as well as seamless coverage and high mobility scenarios with still improved used data rates
    以人为主的看视频之类的服务，对吞吐量的需求非常高
    比较好的体验，比较快的速率，比较大的带宽
  • Massive Machine-type Communications (mMTC) for the IoT, requiring low power consumption and low data rates for very large numbers of connected devices
    支持大量终端连接，万物互联，但比较简单，低速，省电，支持远距离传输（大范围覆盖）
    例如:智能抄表，智慧农田
  • Ultra-reliable and Low Latency Communications (URLLC) to cater for safety-critical and mission critical applications
    紧急的、极致的机器类通信；要求：时延很小，可靠性很高，做出快速的反应。

So 5G should deliver significantly increased operational performance (e.g. increased spectral efficiency, higher data rates, low latency), as well as superior user experience (near to fixed network but offering full mobility and coverage). 5G needs to cater for massive deployment of Internet of Things, while still offering acceptable levels of energy consumption, equipment cost and network deployment and operation cost. It needs to support a wide variety of applications and services.
