5G stands for the fifth generation of cellular networking. The standard ITU Y.3101 “Requirements of the IMT-2020 network” describes the features of 5G networks.
ITU has classified 5G mobile network services into these 3 categories:
• Enhanced Mobile Broadband (eMBB).
• Ultra-Reliable and Low Latency Communications (URLLC)
• Massive Machine-Type Communications (mMTC)
eMBB class 5G NR gNB reference design which is based on Release 15,which is under development. The first release of the system targets frequency range 1 or FR1 specification.
The proof of concept for 5G gNB is demonstrated in real time over hardware platform.
Physical Layer is initially realized completely as a DSP software + RTL firmware solution. The solution in its first version delivers multi Antenna up to 4x4 MIMO. The solution will be qualified against industry’s leading T&M equipment and UE chip vendors. Ongoing work on the radio hardware design will enhance the radio card to support 8TX and 8 RX antenna ports.
