hi maya,
the idea is not to improve the better cell HO per se, but rather, reduce the HO due to other causes. Especially:
– HO due to Quality
– HO due to Interference
At one point the cell will have a natural balance of HO Level vs. HO Better cell, which depends on its radio coverage. You will not be able to change this ratio easily. Drive tests are required. And after, you will tune those ho parameters accordingly:
L RXLEV DL H
L RXLEV UL H
A LEV HO
HO MARGIN
A PBGT HO
Cheers
