so you mean RXLEV_UL = -90dBm and RXLEV_DL = -70dBm ?
here is a simplified link budget, for a cell with 6 TRX:
trx tx = 46dBm
2 * combiners = -9dB
feeder/antenna/radio loss = -100dB (as an example.)
–> RXLEV_DL = -63dBm
ms tx = 33dBm
feeder/antenna/radio loss = -100dB
ul diversity gain = +3dB
–> RLEV_UL = -64dBm
So for such cell, the UL and DL should be similar (assuming your trx-tx-power are around 46dBm).
Since you are seeing a big difference it’s either:
-bad path balance on at least one trx
– power control in UL but no in DL -> either you didn’t activate it , or there is a bad quality in DL therefore the TRX has to transmit stronger.
yes, they can be activated but they will not attenuate the signal symmetrically. If there is a bad RXQUAL in DL? then the DL signal is less reduced than the UL.
I’m quite certain that what you are seeing is due to PC.
Otherwise you should see an unbalanced Path_Balance in the TRX. Since you don’t see it… it has to be PC.
