What are the supported 5G features in srsRAN gNodeB ?

Dear developers,

I want to know the details of supported 5G features of the latest 21.10 srsRAN gNodeB. In the document, it says that srsRAN now supports 5G NSA gNodeB, but I noticed that it only supports limited features like below.

• 15kHz subcarrier spacing
• n3 or n78 band
• numerology 3 (as hardcoded in lib/include/srsran/common/slot_point.h)
• 50 resource blocks for gNB, 50 resource blocks for eNB.
• Round Robin MAC scheduler

Relating to this I have several questions.

• What numerology, TTI, SC is gNodeB exactly using? If gNB supports 15kHz, is it using numerology 0 and 1ms TTI (slot) duration for scheduling?

• Is it possible to increase/decrease the number of resource blocks other than 50 in NR?

• What bandwidth does srsRAN NSA mode support?

• Will other MAC schedulers such as Proportional Fair be implemented in the near future?

It's opensource software,you can help adding features to it
