Request for 3 MHz Bandwidth & 1024QAM Support in srsRAN

[Kaimeliax]

Hello srsRAN developers,

I’m using srsRAN for experimental LTE/5G deployments and noticed a couple of missing capabilities that would greatly help with testing advanced devices:

3 MHz channel bandwidth support (especially for n28 788-791MHz DL)

-Useful for legacy spectrum allocations or narrowband NR deployments.

-Likely requires adjustments to FFT size, resource block mapping, and scheduler logic.

1024QAM modulation support

-Some Rel-17 devices I have can handle 1024QAM, which could be useful for lab testing and throughput benchmarking.

-Would require updating the modulation/demodulation blocks, link adaptation, and scheduler.

I’d be happy to help with testing or providing feedback if these features are added.

Thank you for your amazing work on srsRAN!
