How does downlink power control function works? does the power is decreased for whole cell or its on particular TRX?
it varies for each particular timeslot, depending on the rxev and rxqual of the particular call being carried.
the power control is done per timeslot.can downlink power control cause ping power cell reselection or handovers as for each time slot power is being varied?
No, because :
1/ algorithms already take this into account (as long as there is PC, most of HO cannot be detected … and for the ones that can be detected, they add the power control’s current attenuation into the HO detection threshold)
2/ the thresholds shall be tune so that PC will not be active anymore when a HO could be detected.
For example : Low level HO will appear at -90dBm (let’s say). In this case, PC will attenuate the signal only if the RXLev is better than -80dBm.
If RxLev is Lower than -80dBm, then PC is disabled (it means the TS is sent with maximum power).If you need more explanations, let me know 🙂

I’ll appreciate
Thanx in advance 🙂
Dear Pix
could u explain about Compensation(quality and level)in simple way like u already explined 🙂
