Hello 5G Experts.
In 5G NR SA.
I have serious issue, I’m getting at first transmission pdsch almost more than half attempts of first transmitions "failures " (failure decoding).
But on second/third re-transmissions almost succeeded in all failed previous attempts.
Why it’s happenning? Any idea or suggestion how do I fix that issue?
Note- this issue is happen just when I use 256qam , with 64 qam all fine!!!
My (ss-PBCH-BlockPower) is:
Range : MIN_SSB_POWER - MAX_SSB_POWER --> <!-- ssb_power for Cell 0 --> <SsbPower>-25</SsbPower>
