5G NR offers multi-dimensional enhancements – huge bandwidths and enhanced spectral efficiency enabling gigabit data rates, ultra-low latency and massive connectivity, enabling operators to bring in several business verticals in the cellular ecosystem.
5G NR software stack is one of the key software development paradigms which requires considerable design consideration to enable 5G technology. One of the key shift for 5G would be moving from convention MIMO to massive MIMO. Availability of mmWave spectrum will lead to a dramatic increase in the bandwidth availability but this also comes with challenges of increased path/penetration/propagation loss. This would require accurately calibrated massive/multi-panel antenna, controlled and managed via sophisticated scheduling algorithms to reap the real benefits of the 5GNR.
Attend this session and learn the key design considerations for 5G New Radio software architecture.
Topics Will Include:
- Software: dynamic and flexible slot/symbol based scheduling, beamforming and beam management, number of spatial streams
- Hardware: No. of physical cores, hardware threads, vCPUs, size of RAM / VRAM;
- Deployment: MACRO <->Pico<-> small cell, disaggregated/Collapsible architecture;
- Services: URLLC, mMTC and EMBB;
- Portability: Multiple HW/SW platforms;
- Manageability- Orchestration and Automation, service acceleration;
- Cloudification – cloud native, containerized, microservices.
- Features such as Massive/MU-MIMO, CoMP, RIC, NW Slicing, etc., should be implemented
as a modular ‘plug and play’ modules.
- Static/Run time configurations to the protocol stack from various modules of gNB (OAM, CLi)
- Features enabler (DRX, BWP, Dynamic TDD slot configuration).
- OAM manager
- Defining key KPIs for software efficiency should be created.
- Functional KPIs should be carefully formulated to understand the impact on the system.
- Multiple debugging levels are to be provided to enable MACRO and MICRO prints.
