    3 InterDigital has developed for research and development purposes their FPGA based, NR Rel-15 mmWave prototype platform.  Each Mast Head unit (MHU) contains a 64-element antenna with +40dBm RMS, Anokiwave quad analog phased array chips, 28GHz up/down conversion from/to 5-6GHz IF that is housed in an IP67 weather proof enclosure.

     5[//https://www.interdigital.com/ InterDigital] has developed for research and development purposes their FPGA based, NR Rel-15 mmWave prototype platform.  Each Mast Head unit (MHU) contains a 64-element antenna with +40dBm RMS, Anokiwave quad analog phased array chips, 28GHz up/down conversion from/to 5-6GHz IF that is housed in an IP67 weather proof enclosure.
    46The baseband unit, Modem Processor Unit (MPU) is designed according to 3GPP Rel-15 PHY specifications and is implemented in a Xilinx MPSOC FPGA.  The MPU contains two Xilinx Zu15EG SOM modules (2nd for future use), IF frontend, USB 2.0/3.0, SFP ports, Gigabit Ethernet interfaces and a SMA connection to the MHU.     
    57The MPU is configurable as either a 5G UE or gNB with the appropriate PHY, thin MAC/RLC functionality.
    68The current implementation supports a single UE and gNB, however the system was designed to support 2 UEs using different gNB beams and appropriate changes to the UE scheduler.

    1011The NR platform is a TDD system with a baseband that supports FR2, 120KHz sub-carrier spacing, fixed frame format (modified format 32), 200MHz bandwidth, SISO, NR LDPC coding for data channels, convolutional coder* for PUCCH and PDCCH and 8 SSB beams with CSI reporting for link adaptation. The MHU/MPU system supports horizontal beam angles of: ± 45deg, ± 30deg, ± 15 deg, 0deg and a single fixed vertical beam.
