3.1.2.2 Communication Settings
The R&S CMW500 LTE driver provides a configuration dialog for the basic properties of
the LTE downlink signal of the R&S CMW500 ("Cell Setup" and "Connection" settings).
Access: "Communication Settings" button in the "OTA Auto Test Template" dialog; see
​
figure 2-4 .
The "Cell Setup" parameters are identical to the single-antenna test case; see
​
chap-
ter 2.1.2.2, "Communication Settings" , on page 11. In the "Connection" tab of the driver
configuration dialog, you can select the DL "Transmission Scheme" and the allocated DL
and UL resource blocks. Check "Setup Connection" to transfer your settings to the R&S
CMW500.
To measure in line with the test case "peak performance in spatial multiplexing mode",
select "Open Loop Multiplex" as a transmission scheme and to configure a high-order
modulation scheme, typically 64QAM, with a high transport block size index (TBSI).
For detailed information about the communication settings, refer to the R&S CMW500
documentation. Click "OK" to confirm your settings and return to the "OTA Auto Test
Template" dialog.
