Most of the cell have 2 TRXs (1 twin TRE). Coverage mode MUST use Tx diversity? (correct me if i’m wrong)
From my understand
– At OMC: configure twin TRE as a single TRX for coverage mode.
– At site, connect 2 Tx ports of the twin TRE to 2 Tx ports of the ANC (w/o combining).
-> The X-pol antenna will be Tx diversity. No need to install another antenna for the sector?
How about uplink? Is it mandatory to have TMA, else CSSR will be degraded?
