LTE TDD
For Waveform Playback (ARB) capability.
This topic describes the settings of the Downlink > Synchronization Signals node for a Basic TDD carrier.
Enables or disables the Primary Synchronization Signal (PSS) transmission.
In TDD, PSS is transmitted in the DwPTS of subframes 1 and 6.
See 3GPP TS 36.211.
