srsUE extention to 30 kHz SCS support #1237

Closed aris002 closed 1 year ago

aris002 commented 1 year ago

Greetings,

I know that this has been asked a lot, and I don't know if this is the correct space to address this but I would like to ask. Which layers must be changed to be able to support a 30 kHz scs e.g., n5 for the second configuration for FDD and scs = 30 kHz. I have read both the frame structure from sharetechnote, nr-explained and the 3GPP TS for 5G but I can't grasp which part of the UE must be altered. Is this a ground-up rebuild or some new functions and alterations in existing functions? I am not asking for a solution, just a point to the right direction.

Greetings,

The UE architecture is still based on the 4G implementation, meaning that a ground-up redefinition must be done. The frame structure and the physical layer as a set must be redefined and modified in order for other numerologies to be used. This is what I managed to understand. Therefore, this issue will be closed, since there is no answer that would satisfy it.
