5G NR PUCCH Integration by Spanidea Systems

Background: Spanidea Systems collaborated with premier academia and utilized Xilinx, MATLAB, and RTL (Register Transfer Level) to develop and integrate the 5G New Radio (NR) Physical Uplink Control Channel (PUCCH). The project involved designing and implementing 3GPP (Release-15, 38.211, and 38.212) compliant algorithms for the transmit PUCCH. The goal was to develop a robust and efficient PUCCH solution capable of carrying control information from the User Equipment (UE) to the gNB (gNodeB).

Solution Provided by Spanidea Systems:

  • Design of 5G NR PHY Layer Algorithms: Spanidea Systems was responsible for the design and development of 3GPP-compliant 5G NR PHY layer algorithms specifically for the transmit PUCCH. These algorithms encompassed various building blocks mentioned in the 3GPP standards, such as channel coding, rate matching, modulation, and more. The algorithms formed the core deliverables of the project.
  • Development of Transmit PUCCH Format 2: Spanidea Systems focused on the development of the transmit PUCCH format 2, which serves as the channel for carrying control information from the UE to the gNB in the 5G NR system. The implementation of this format was executed using MATLAB and FPGA (Field-Programmable Gate Array) technologies. MATLAB provided a simulation environment for algorithm development and validation, while FPGA allowed for real-time hardware implementation.
  • Integration and Evaluation: Individual modules developed in MATLAB and RTL were integrated to create a complete PUCCH solution. The integrated solution underwent thorough testing and evaluation to ensure its compliance with the 3GPP standards and its performance in real-world scenarios. Xilinx hardware was utilized for the testing and validation of the physical channel, providing a reliable and industry-standard platform.
  • Conclusion: Spanidea Systems successfully designed and integrated the 5G NR PUCCH as part of their collaboration with premier academia, leveraging Xilinx, MATLAB, and RTL. The project involved developing 3GPP compliant PHY layer algorithms for the transmit PUCCH, including various building blocks such as channel coding, rate matching, and modulation. The development of the transmit PUCCH format 2 was executed using MATLAB and FPGA technologies, allowing for algorithm validation and real-time hardware implementation. Thorough testing and evaluation on Xilinx hardware ensured the reliability and performance of the PUCCH solution. Spanidea’s contribution to the 5G NR PUCCH integration demonstrated their expertise in 5G technology and their ability to deliver robust and compliant solutions for next-generation wireless systems.
