RBS 2106 and RBS 2206 Radio Configurations
• The configurations have TRX connected to different antennas in the same
antenna system.
One possible application using SPB together with hybrid combiner is creating
overlaid and underlaid cells during cell planning, as described below:
1 One underlaid cell consists of the second TRX in the first dTRU and the
first TRX in the second dTRU. SPB is used in this cell.
2 One overlaid cell consists of the two other TRXs. SPB is not used in this
cell.

The section does not include any additional site cell configurations. The section
specifies which configurations support Transmitter Coherent Combining (TCC).
A minimum of two TRXs is required in order to support TCC.

TCC is supported in all of the SCCs with CDU-G, specified in 6HFWLRQ  RQ SDJH
 which fulfill the following conditions:
• The configurations use hybrid combiner.
• The configurations have two TRXs within the same dTRU.
