Table 1. Structure XDfePrach_InternalCarrierCfg Member Description
Member Description
Enable [0,1] Enable/Disable CC while still reserving its slot in the TDM - set by helper functions when building the configuration.
SCS [0-4] CC sub-carrier spacing.

Required to determine Slot boundaries:

  • 0: 15KHz spacing
  • 1: 30KHz spacing
  • 2: 60KHz spacing
  • 3: 120KHz spacing
  • 4: 240KHz spacing
CCRate [0-3] The sample rate for the CC.

This is also the decimation rate required to decimate the CC down to Fc/16 Ms/s:

  • 0: Fc/16 Ms/s, implies 1x decimation to get to Fc/16 Ms/s)
  • 1: Fc/8 MS/s, implies 2x decimation to get to Fc/16 Ms/s)
  • 2: Fc/4 MS/s, implies 4x decimation to get to Fc/16 Ms/s)
  • 3: Fc/2 MS/s, implies 8x decimation to get to Fc/16 Ms/s)
