v3 v4 1 1 = [//https://www.interdigital.com/ InterDigital] 5G NR Platform = 2 2 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. 3 [[Image(id-nr-bd.png, 200px, align=right)]] 4 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. 4 6 The 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. 5 7 The MPU is configurable as either a 5G UE or gNB with the appropriate PHY, thin MAC/RLC functionality. 6 8 The 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. 7 9 8 [[Image(id-nr-bd.png)]]9 10 10 11 The 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. … … 17 18 18 19 || Symbols used for DL and UL shared and control channels || Symbols used for PSS and PBCH during slots carrying SSB information. || Symbols used for PRACH during PRACH slots || 19 || [[Image(slots1.png, 250px)]] || [[Image(slots2.png, 250px)]] || [[Image(slots3.png, 250px)]]||20 || [[Image(slots1.png, 250px)]] || [[Image(slots2.png, 250px)]] || [[Image(slots3.png, 250px)]] || 20 21 21 22
