For carrier aggregation, select different DL channels for PCC and SCC. The two chan-
nels must not overlap and can be located in the same band or in different bands.
The relation between operating band, carrier frequencies and channel numbers is
defined by 3GPP (see
chapter 2.2.16, "Operating Bands"
an additional band if option R&S CMW-KS525 is available, see
You can change the operating band and the channels in all main connection states. In
state "Connection Established" you can either change one parameter directly or you
can perform a handover to reconfigure several parameters, see
Remote command:
Frequency Offset
You can specify positive or negative offsets to be added to the carrier center frequen-
cies. This is useful for example if the UE has a frequency offset relative to the channels
defined by 3GPP.
To configure different PCC and SCC downlink settings for carrier aggregation scenar-
ios, enable "Use Carrier Specific".
Remote command:
Band Definition
Displays the definition of the selected operating band. Operating band "User-Defined"
can be edited.
Option R&S CMW-KS525 is required for user-defined bands.

, for TDD usually the same frequency is used in UL and DL, but different fre-
quencies can be configured for user-defined bands.
Remote command:
Channel Subdivision ← Band Definition
Displays the spacing between center frequencies of two adjacent channels, always
100 kHz - also for user-defined bands.
