What do you mean by SRB here?
Scheduling Resource Blocks.
Yes, correct.
Never heard such definition…
This is a new one.
Not sure if this is something proprietary, never read it in the specs.
SRB is terminology used in Ericsson.
It’s not standard term.
I checked in Ericsson LTE air interface guide not able to find such terminology.
Is it related to some feature or parameter?
Try searching Scheduling Block.
SRB is the signaling that carry messages signaling that you can calculate in major KPIs (RRC, NAS…).
Note: there is SRB0, SRB1 & SRB2 in LTE.
In 5G, there is the same + SRB3 (new one).
SRB concept there is Ericsson system for RRC & NAS signaling.
Yes SRB is signalling Radio Bearer agreed.
The thing that I was speaking about was Scheduling Resource Blocks.
Lets keep same understanding SRB is Signalling Radio Bearer only.
A scheduling block consists of two RBs adjacent in time and with the same subcarriers.
A scheduling block is the smallest downlink unit that can be scheduled to UE.
Yes its agree scheduling block is smallest allocated unit ie PRB.
It’s not SRB.
At least 1 PRB to UE.
So we were actually confusing between SRB and SB here?
Yes, I was talking about this.
It’s all clear now, thanks.
