Please refer spec 36.101 section 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 - 65535.

The relation between EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL_low and NOffs-DL are given in Table 5.7.3-1 (Spec 36.101) and NDL is the downlink EARFCN.

FDL = FDL_low + 0.1(NDL – NOffs-DL)

FDL_low: The lowest frequency of the downlink operating band

NDL: Downlink EARFCN

NOffs-DL: Offset used for calculating downlink EARFCN

The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where FUL_low and NOffs-UL are given in Table 5.7.3-1 (Spec 36.101) and NUL is the uplink EARFCN.

FUL = FUL_low + 0.1(NUL – NOffs-UL)

FUL_low: The lowest frequency of the uplink operating band

NOffs-UL: Offset used for calculating uplink EARFCN
