According to the 3GPP specifications, carrier aggregation is user-specific and thus dif-
ferent users served by the same base station can use different carriers. Moreover, the
different users can also have different primary cell (PCell). In this implementation, how-
ever, all users use the same carrier aggregation configuration, or with other words, the
primary and secondary cells (SCells) are the same for all configured users. Hence,
there are 16 carriers per node, not per user.
The number of simulated carriers is set automatically, depending on the selected sys-
tem configuration:
●
For "System Configuration > BB Sources = Separate", "Number of Carriers = 1"
●
For "System Configuration > BB Sources = Coupled", "Number of Carriers = Sys-
tem Configuration > Entities".
Remote command:
[:SOURce<hw>]:BB:NR5G:NODE:NCARrier on page 167
RF Phase Compensation
If enabled, applies a frequency-related phase compensation after each symbol, as
specified in TS 38.211.
Use the parameter Frequency in GHz to set the carrier frequency to be compensated.
Remote command:
[:SOURce<hw>]:BB:NR5G:NODE:RFPHase:STATe on page 168
Carrier table
Comprises the carrier settings. There is one table row per carrier.
Carrier ← Carrier table
Displays the automatically assigned carrier names.
Remote command:
via suffix at CELL<ch>
Cell Indicator ← Carrier table
Sets the cell indicator, to identify each of up to 16 carriers.
The cell indicator is unique and unambiguous index used to address the cell, for exam-
ple for cross-carrier scheduling.
Remote command:
[:SOURce<hw>]:BB:NR5G:NODE:CELL<ch0>:CINDicator on page 167
Cell ID ← Carrier table
Sets the cell identity of the selected cell.
The physical layer cell ID N
ID
cell
is used for synchronization between network and user
equipment. It identifies a specific radio cell in the 5G NR network. The cell ID is a value
between 0 and 1007, calculated as follows:
N
ID
cell
= 3N
ID
(1)
+ N
ID
(2)
Unlike the Cell Indicator, cells can use the same "Cell ID".
