For carrier aggregation scenarios you can configure different PCC and SCC DL cell
bandwidths.
Remote command:
Physical Cell ID
The cell ID is used for generation of the physical synchronization signals. During cell
search the UE determines the cell ID from the primary and secondary synchronization
signal.
The physical cell ID can be set independent of the E-UTRAN cell identifier sent to the
UE via broadcast (see
If you use carrier aggregation, configure different values for PCC and SCC.
Remote command:
Cyclic Prefix
Defines whether a normal or extended Cyclic Prefix (CP) is used.
An extended cyclic prefix cannot be combined with the transmission mode 8 (combina-
tion not foreseen by 3GPP).
Option R&S CMW-KS510 is required for extended CP.
Remote command:
Sounding RS (SRS)
Enables support of SRS. The information that the cell supports SRS is then broadcas-
ted to the UE. During connection setup, the UE is requested to send a sounding refer-
ence signal.
Uplink SRS signals can be measured using the "LTE SRS" measurement included in
option R&S CMW-KM500/-KM550.
Remote command:
SRS
The parameters "srs-SubframeConfig" and "srs-ConfigIndex" are signaled to the UE.
Their values can be set automatically or manually via the following parameters.
These parameters determine the SRS timing. In subframes with SRS transmission,
only a single UE in the cell sends an SRS symbol. All other UE in the cell send a "blank
SRS symbol".
