  • Scenario:

    Super real-time and reliable connections

    Low E2E latency delay and reliable communication enabling

    critical machine-type applications

    Empowering industries to embrace new technologies in their

    processes

    Traffic efficiency and safetyTraffic efficiency and safety More efficient use of road infrastructure

    Reduce risk for traffic incidents

  • Scenario: Ubiquitous things communicating

    Very large number of small, simple, and inexpensive devices

    Requirement for long battery lifetime, scalability, and

    adaptability

    Inexpensive = small battery, simple device

    Massive deployment ofsensors and actuators

    Handle a massive number of devices Very low cost devices with long battery lifetime

    Provide protocol scalability and coverage

  • ROAD TO 5G Technology Components

    Examples

  • Massive MIMO: CSI Error

    Transmission scheme 24x24 MIMO-OFDM eigenmode

    Signal bandwidth 400 MHz

    Subcarrier spacing 195 kHz

    Maximum bit rate 35.3 Gbps (64QAM, 3/4)

    Example of contribution:30 Gbps simulation using 11 GHz band

  • Beyond Uplink & Downlink: two-way comm.

    Traditionally, the designs of

    the uplink and the downlink

    are decoupled

    The ideas related to

    wireless network coding
