The timing is configured via a cell-specific setting and a UE-specific setting:
●
At time instances with configured UE-specific SRS, the UE sends an SRS symbol.
All other UE send a "blank SRS symbol".
●
At time instances with cell-specific SRS but without UE-specific SRS, the UE sends
a "blank SRS symbol" (and another UE sends an SRS symbol).
Option R&S CMW-KS510 is required.
Manual Configuration ← SRS
With disabled "Manual Configuration", the parameter "srs-SubframeConfig" is set to 3
for FDD and to 0 for TDD. The parameter "srs-ConfigIndex" is set to 7 for FDD and to 0
for TDD. These values are specified in 3GPP TS 36.521 for example for SRS time
mask tests.
With enabled "Manual Configuration", the signaled values are configured manually via
the parameters "Subframe Configuration" and "Configuration Index".
Remote command:
Subframe Configuration ← SRS
Configures the parameter "srs-SubframeConfig" manually. This is only possible if
"Manual Configuration" is enabled.
The value determines the cell-specific SRS timing. The meaning of the individual val-
ues is specified in 3GPP TS 36.211, section 5.5.3.3.
Remote command:
Configuration Index ← SRS
Configures the parameter "srs-ConfigIndex" manually. This is only possible if "Manual
Configuration" is enabled.
The value determines the UE-specific SRS timing. The meaning of the individual val-
ues is specified in 3GPP TS 36.213, section 8.2.
Remote command:
TDD
The following parameters configure TDD-specific settings, not relevant for FDD.
Uplink Downlink Configuration ← TDD
Selects the uplink-downlink configuration of a TDD signal, see
ration defines a combination of uplink subframes, downlink subframes and special sub-
frames within a radio frame.
