i’m sorry but i have no idea what kind of feature is behind this parameter. By default, after a handover, the MS emits at full power until the new BTS sends him a new MS TX power on SACCH.
With this parameter, It looks like the MS can keep the previous power before HO… but i don’t see how that’s possible. It might work for collocated sites ? Or based on DL measurements, the MS can predict the path loss difference in UL between serving cell and target cell ???
I really have no idea how that would work…
