Chapter 2: Hardware setup 3
• When RF cables are used, cabling must follow the instruction provided in the following
sections. TX and RX gains must be adjusted accordingly. See [TX:RX gain setting],
page 13, for more details
Note: When using RF combiners, unused ports of the combiners must be terminated with
RF terminator or absorber especially when using frequency above 2.5Ghz. Otherwise big inser-
tionlosses may happen and downgrade the RF performances.
2.2.1 RF connection for one Cell MIMO 2x2 in FDD mode
Note: For SISO test, connection between TX2/RX2 and UE (RX2) is not required
2.2.2 RF connection for two Cells MIMO 2x2 in FDD mode
When two cells are configured at eNodeB side, two SDR cards are required at UE simulator
side even if both cells are intrafreq cells or use the same RF antenna port. Each SDR card is
dedicated to one specific cell.
In the picture below, both eNodeB cells use a different antenna port (RF#1 and RF#2). This
cabling is releveant for two neighbor cells or for a Carrier Aggregation test.
Note: When both cells are using the same eNodeB antenna port, please refer to the second
picture (one eNodeB antenna port) for the RF connection.
Note: This cabling also corresponds to a NSA cell configuration with one LTE cell 2x2 MIMO
and one NR cell 2x2 MIMO
