CFI
The Control Format Indicator (CFI) sets the number of OFDM symbols used for the PDCCHs in a subframe.
Transmission Bandwidth Configuration
Number of PDCCH Symbols per Subframe
> 10 RB (1.8 MHz)
CFI value
≤ 10 RB
CFI + 1
The CFI is mapped to the Physical Control Format Indicator Channel (PCFICH) in the physical layer.
Mode
BSE, FDD
Range
1 - 3
Preset
ACELL = 2 / BCELL = 2

CFI (Normal SF)
The Control Format Indicator (CFI) sets the number of OFDM symbols used for the PDCCHs in a subframe,
that is reserved for downlink transmission.
Transmission Bandwidth Configuration
Number of PDCCH Symbols per Subframe
> 10 RB (1.8 MHz)
CFI value
≤ 10 RB

CFI + 1
1. ≤ 10 RB is currently not supported as this is 1.4 MHz BW.
The CFI is mapped to the Physical Control Format Indicator Channel (PCFICH) in the physical layer.
