SCH.This topic discusses some of the features of the Advanced LTE FDD carrier's long waveform.
The relationship between the Waveform Generation Length (UL or DL) and Transmission Configuration Length is shown in following figure. (For more information on the Transmission Configuration Length parameter refer to the Channel Setups Advanced LTE UL or and DL topics.)
If Transmission Configuration parameter is in the channel, the configured setting pattern in Transmission Configuration is repeated for the channel generation until the end of the waveform (DL-SCH, DCI, UL-SCH, UCI). (For more information on the Transmission Configuration parameter refer to the Channel Setups Advanced LTE UL or and DL topics.)
The Transmission Configuration Length parameter's value specifies the repeating period (in frame) of the Transmission Configuration which is configured the channel's Tx Sequence definition.
Example: Where the Transmission Configuration Length is set to 20 ms (2 frames), Frames #0 and #1 configurations (Sequences #1 through #20) will be repeated while generating SCH.
