Criteria for OL to UL HO:
SS_non-BCCH+FBOFFS< BSTXPWR-LOL-LOLHYST Criteria for UL to OL HO: SS > BSTXPWR-LOL+LOLHYST
When optimising the FBOFFS for the subcell changes, the SCLD, LOL, LOLHYST, DTCB, DTCBHYST, NDIST, NNCELLS and TAOL parameters should also be considered.
By increasing the LOL in a multi band cell with the non-BCCH frequency band in the OL subcell, the coverage of this non-BCCH band is increased.
