Setting up a Connection with Carrier Aggregation
The following procedure describes how to set up a downlink connection with PCC and
SCC.
1. Connect your UE to the R&S
CMW (see
chapter 2.2.1.4, "Test Setup for Carrier
2. Select a scenario with carrier aggregation and configure the RF settings for PCC
and SCC.
The PCC DL channel and the SCC DL channel must not overlap.
3. Configure the SCC activation mode as desired, see
4. Configure any other signaling application settings as desired, for example DL
power, cell setup and connection settings.
If you change the physical cell ID or the E-UTRAN cell identifier, set different val-
ues for PCC and SCC.
The connection setting "Keep RRC Connection" must be enabled if automatic SCC
activation shall be used or if the SCC shall be added in packet switched state
"Attached".
5. To turn on the primary cell signal, press "ON | OFF" and wait until the "LTE Signal-
ing" softkey indicates the "ON" state and the hour glass symbol has disappeared.
6. Switch on the UE.
The UE synchronizes to the DL signal and attaches. Note the packet switched
state in the main view and wait until it equals "Attached".
7. If the RRC state is "Idle", press the "Connect" hotkey to set up an RRC connection
on the PCC.
Note the RRC state displayed in the main view and wait until it equals "Connected".
8. Depending on the configured SCC activation mode, an SCC has already been
added and activated automatically, or you can now activate it manually.
● Mode "Auto":
The SCC has been added and activated upon UE attach if the setting "Keep
RRC Connection" is enabled. Otherwise press the "Activate MAC" hotkey to
add and activate the SCC.
● Mode "Semiautomatic":
Press the "Activate MAC" hotkey to add and activate the SCC.
● Mode "Manual":
To add and activate the SCC, press the hotkey "SCC On", then "SCC add
RRC", then "SCC activate MAC".
