deep k,

samples count for PC : you can put it to “2”
samples count for HO : should be > or = 4

now let me translate your thresholds settings in a more “readable” way :

in UL :
HO LEV = -110 + 22 = -88dBm
PC LEV = -86dBm to -76dBm
HO QUAL = 3
PC QUAL : 1 to 3

in DL :
HO LEV = -110 + 25 = -85dBm
PC LEV = -82dBm to -72dBm
HO QUAL = 3
PC QUAL : 1 to 3

Ok.
You are triggering your HO way too fast !!
These are my recommendations :
Samples count for PC = 2

HO QUAL (UL or DL) = 4
UL/DL PC QUAL = 1 to 3 (good, don’t change it)

DL HO LEV = -90dBm (20)
UL HO LEV = -96dBm (14)

DL PC LEV = -80 to -70 (20 to 30)
UL PC LEV = -86 to -76 (24 to 34)

Keep at least 10dB between your lower PC thresholds and your HO thresholds. And speed up the PC averagings.
Check also your “step size” (incremental and decremental steps of power control. they should allow about 12dB increments in extreme situations).
