Test Setup for Carrier Aggregation Scenarios
The Carrier Aggregation (CA) scenarios allow you to establish a Release 10 connec-
tion with two component carriers in the downlink. The two carriers are called Primary
Component Carrier (PCC) and Secondary Component Carrier (SCC).
For each downlink carrier you can have one output path (SISO, scenario "2CC CA - 2
RF Out") or two output paths (e.g. MIMO nx2, scenario "2CC CA - 4 RF Out").
So a test setup for carrier aggregation involves one uplink and two or four downlink sig-
nals. Each output path must use a different TX module. The two output paths of a car-
rier must use different RF connectors.
The first PCC output path and the first SCC output path can be routed to the same
connector (advanced frontend required) or to different connectors. The same applies to
the second PCC and SCC output paths. Select the appropriate setup depending on the
number of RX antenna connectors of your UE. There is no need for external combin-
ers.
The following example setup is suitable for CA with MIMO nx2 and a UE with only two
antenna connectors. RF 1 COM is used for the uplink, the first PCC downlink and the
first SCC downlink. RF 3 COM is used for the second PCC downlink and the second
SCC downlink.

The following example setup is suitable for CA with MIMO nx2 and a UE with four
antenna connectors. Each downlink signal is routed to a different connector.
