[srsran-users] New srsRAN Project

[Paul Sutton]

Hey SDR Hackers,

For the past 18 months, we've been working on a new 5G project behind 
the scenes here at SRS and this week we're very excited to share the 
first release with you.

Our new codebase is a complete 5G RAN solution, featuring an ORAN-native 
CU/DU with the complete stack from I/Q to IP developed by the SRS team. 
As you'd expect, the project is open source under AGPLv3, portable 
across processor architectures including x86/ARM and with minimal 
third-party dependencies.

While already coming in at over half a million lines of code, the 
project is still young and you can expect regular feature updates over 
the coming months. Key current features include:
- 100MHz SISO single-cell
- FDD/TDD duplex modes
- 15/30 kHz subcarrier spacings (FR1)
- x86/ARM support with AVX2/AVX512/NEON SIMD support
- Tested with up to 64 UEs in simultaneous active state
- USRP B/X/N family support

Key features we're currently working on include:
- Mobility
- MIMO
- ORAN 7.2 fronthaul
- Independent DU/CU-CP/CU-UP apps
- E2 interface with KPM and RC E2SMs
- O1 interface to SMO
- Release 17 NTN features

With the release of this new codebase, we plan to make some changes to 
project and repo naming. The current srsRAN codebase will become "srsRAN 
4G" and the new codebase will be the "srsRAN Project". Accordingly, the 
srsRAN repo will become srsRAN_4G and the new repo will be srsRAN_Project.

Along with the new codebase, we're providing extensive documentation 
including user manual, developers guide and knowledge base. We will 
continue to host documentation for both codebases at docs.srsran.com. 
You'll still find the project website at www.srsran.com providing a 
one-stop-shop for everything srsRAN-related.

We'll provide more details during the week as soon as we push the 
release but for now, we just wanted to give you a heads-up on the coming 
changes. We look forward to getting the code into your hands and seeing 
what you can achieve with it.

Talk soon,
The SRS Team
