I tried power so far and got results.
So PBCH power improved RACH failures you mean?
Yes, because my cases are usually in dense and deep indoors issues.
Power Increase.
Improve coverage!
Apart from that some are improved by ZCZ adjusting.
Yes, can be coverage gap or collision too.
Yes, you can review your RACH planning.
So that’s why try power along with collision and don’t know if you’d are using ZCZ.
I think RSRP SSB threshold can help too.
Is it possible?
You can try, I haven’t tried that yet.
So not much idea.
Yes, so what about SSB periodicity decrease impact from 20 to 5 msec?
It will increase the SSB overhead, but reduce the access latency, also it has slight improvement on peak throughput.
Why impact on throughput?
MCS should depends on PDSCH SINR.
You’re right, sorry.
It will be slight reduction in TP, not increase.
But with more periodicity, you have less bandwidth.
I have a question along similar line:
What happens when we move SSB from 1st half frame to 2nd?
Keeping the periodicity same?
How does that help?
Actually I didn’t experience such case, but I think nothing will be changed except some little more latency will be observed I believe.
Because we will wait for 2nd half of the frame to read the SSBs.
Yeah…hard to think why this half frame bit is so imp!
I would not think they introduced it to increase latency.
Must be serving some purpose.
Just not sure why…
Let’s wait the other engineers, maybe somebody knows…
What is the value of event B1. I think B1 event above -119dbm, is decrease RACH SR
