5.7.3 Carrier frequency and EARFCN

The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range 0 – 262143. The relation between EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where $F_{DL\_low}$ and $N_{Offs-DL}$ are given in Table 5.7.3-1 and $N_{DL}$ is the downlink EARFCN.
$F_{DL}$ = $F_{DL\_low}$ + 0.1( $N_{DL}$ – $N_{Offs-DL}$ )

The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where $F_{UL\_low}$ and $N_{Offs-UL}$ are given in Table 5.7.3-1 and $N_{UL}$ is the uplink EARFCN.
$F_{UL}$ = $F_{UL\_low}$ + 0.1( $N_{UL}$ – $N_{Offs-UL}$ )
